description: Food system STEM projects have the capacity to motivate high school students in urban schools. This study explored food as a context to engage students because everyone interacts with food on a daily basis and has had cultural experiences related to food. An integrated STEM approach in combination with a systems thinking approach challenged students to make transdisciplinary connections, view problems from different perspectives, analyze complex relationships, and develop 21st-century and career skills (Hilimire et al., 2014; Nanayakkara et al., 2017). The purpose of this study was to describe and explain the relevance students perceive in Ag+STEM content by measuring high school students' self-efficacy, intrinsic value, attainment value, cost value, and utility value after participating in a food system STEM project. The study was informed by Eccles and Wigfield’s (2020) Situated Expectancy Value Theory. The convenience sample of this study was comprised of high school students from metropolitan area schools. High school students completed a food system STEM project with a food system context. Quantitative data was collected using the developed Food System Motivation questionnaire. Data were collected through a retrospective pre-test and a post-test. Descriptive statistics were used to analyze the data including means and standard deviations. Relationships were explored by calculating correlations. There were four conclusions from this study. First, high school students were somewhat interested, felt it was important to do well, and agreed there were costs regarding participation in the food system STEM project. Second, high school students reported higher personal and local utility value motivation after completing the food system STEM project. Third, high school students were somewhat self-efficacious in completing the project tasks and completing the project tasks informed by their cultural identity and experiences. Fourth, intrinsic value and attainment value motivation (independent variables) were related to personal and local utility value motivation and project and cultural self-efficacy motivation (dependent variables). Implications for practice and recommendations for future research were discussed.

description:
Continuously growing demands for exploitation and storage in the near subsurface require up to date information on the setting of the unconsolidated Cenozoic rocks. Of special relevance are depth information on the base Quaternary for mapping Pleistocene tunnel valleys to answer hydrogeological questions and for preparing 3D subsurface models. Current studies in Saxony-Anhalt still incorporate the results of the map series “Lithofazieskarte Quartär” (LKQ), which was prepared between 1968 to 1984. However, newly available evidence from digitized seismic depth maps and drilling results suggest an update of the depth information of the base Quaternary in Saxony-Anhalt.

In a first step, wells penetrating the Quaternary were exported from the well database of Saxony-Anhalt and their stratigraphies were simplified. Relevant wells were subsequently selected by unambiguous stratigraphy, similarity of well elevation with DGM height, cross validation and comparison to the well database of the LKQ. The remaining 85.000 relevant wells were combined with newly stratified wells and digitized isobaths of the base Quaternary from seismic data and former studies to a new base map. Subsequent quality control comprised tests of different gridding algorithms and profile drawing.

The new depth map of the base Quaternary reveals updated pathways of Pleistocene tunnel valleys of up to 500 m thickness in the Altmark region and in Eastern Saxony-Anhalt. Here, changes to the LKQ are largest. Minor differences are observed in the western and southern parts of Saxony-Anhalt with thicknesses usually less than 50 m.
Endovascular treatment in acute ischemic stroke patient on factor Xa inhibitor

description: Warfarin has primarily been used for prevention of ischemic stroke in patients with atrial fibrillation for nearly 30 years [1]. More recent studies and trials have demonstrated the efficacy of new oral anticoagulants (NOACs) such as direct thrombin inhibitors and factor Xa inhibitors as a source of alternative therapy in preventing ischemic strokes in patients with atrial fibrillation. These NOACs also have the added benefit of minimizing labor intense methods such as the routine coagulation parameter monitoring that is often done in the case of warfarin. Therapeutic efficacy was elucidated by the ROCKET-AF trial which demonstrated noninferiority of rivaroxaban, a factor Xa inhibitor, to warfarin in prevention of stroke and systemic embolism [2]. However, treatment of patients who experience an acute ischemic stroke despite being on the aforementioned NOACs such as rivaroxaban has not been documented. The only FDA approved treatment for acute stroke with class I recommendation and holding level A evidence is intravenous recombinant tissue plasminogen activator (IV tPA) [3]. Even patients on warfarin who suffer from an ischemic stroke may be treated with IV tPA provided that the international normalized ratio (INR) and platelet thromboplastin time (PTT) are not elevated [4]. However, owing to the relatively newer profiles of the various NOACs, there are currently no readily available assays in existence to determine their level of anticoagulation in a NOAC user. Inability to determine the state of anticoagulation in turn makes decision to provide treatment with IV tPA difficult in such patients who suffer from ischemic strokes. Several other articles have been published describing the incidence of complications and recommended discontinuing direct thrombin inhibitors preprocedural [5,6]. To counter such dilemma, intra-arterial tPA (IA tPA) proves to be a viable therapeutic option when the administration of IV tPA is contraindicated [5]. The safety profile of IA tPA for clot dissolution is further strengthened owing to the smaller amount of the total dosage that is ultimately required for clot delivery. In fact, the efficacy of IA tPA application in patients with elevated INR secondary to warfarin use has been reported [7,8]. However, to our knowledge, there are no prior reports of administering IA tPA and mechanical thrombectomy in a patient who is on a factor Xa inhibitor. We report a case of a 79-year-old man on rivaroxaban who presented with acute onset of right gaze deviation and left-sided weakness, and showed clinical improvement with IA tPA

description:
The eastern margin of Asia formed an active Andean-type margin from the Triassic until the Cretaceous. SE Vietnam and West Borneo were located at the southern end of this subduction zone. Triassic igneous rocks in Indochina are usually interpreted to be related to the closure of the Paleo-Tethys. However, in West Borneo Triassic I-type granitoids and associated fore-arc volcaniclastic turbidites can be attributed to west-directed subduction of the Paleo-Pacific. The arc can be traced through the South China Sea to SE Vietnam and Hainan with magmatism continuing into the Jurassic, although with a diminished intensity. Thus, West Borneo can be correlated with the Indochina basement. With the beginning of the Cretaceous and docking of the Banda block (which consists of SW Borneo) with West Borneo, large Paleo-Pacific subduction-related magmatic provinces formed in southern Borneo and SE Vietnam. Lower Cretaceous I-type granitoids are thereby dominant in Borneo, while in SE Vietnam Upper Cretaceous I-type rocks are more abundant. At around 80 to 85 Ma magmatism changed from I-type to A-/S-type affinities, suggesting cessation of the Paleo-Pacific subduction and a switch to post-orogenic magmatism that lasted until the end of the Cretaceous. The Mesozoic igneous record of the West Borneo and SE Vietnam provinces is remarkably similar and indicates a common tectonic history associated with the various stages of Paleo-Pacific subduction beneath eastern Asia.

description:
Aquifer thermal energy storage (ATES) is a promising technique for the short- to long-term storage of reusable thermal energy in the subsurface. Many ATES projects suffer from operational issues or failures. Main causes are clogging, mineral precipitation and corrosion affecting both the aquifer matrix and technical infrastructure (e.g., pipes, heat exchangers), as well as unfavourable recovery rates due to convective and conductive heat energy losses across natural system boundaries.

While most systems address natural porous aquifers, a range of formerly active underground mines has been considered for ATES as well. The ongoing research project “MineATES” focuses on chances and limitations of such man-made systems.

Specifically, an in-situ real laboratory has been set up at the former silver mine “Reiche Zeche” in Freiberg, Germany, to simulate periodical heat exchange between mine water and surrounding rock. Hydro-/geochemistry changes will be logged simultaneously to the monitoring of heat propagation in both water and rock. In parallel, laboratory-scale flow-through column and batch experiments with multiple combinations of rock types and mine water compositions will be carried out at defined temperatures (~ 5°C to 50°C) to identify scales, types and locations of possible mineralization and further chemical alteration. Reference materials (rocks and mining waters) from the “Reiche Zeche” will be compared to materials from the Saxonian mines “Ehrenfriedersdorf” (former tin ore mine) and “Lugau/Oelsnitz” (former hard coal mine).

The project results are to be compiled into a criteria catalogue, providing guidelines for assessing if and how a mine could be used as an ATES system.

description:
The triple oxygen isotope composition (δ18O and ∆’17O) of atmospheric CO2 provides valuable information about CO2 sources and carbon exchange fluxes between atmospheric reservoirs [1-2]. For example, stratospheric CO2 has a large positive 17O-anomaly due to photochemical processes. The ∆’17O of tropospheric CO2 is primarily influenced by carbonic anhydrase-catalyzed oxygen isotope exchange between air CO2 and water in vegetation, resulting in an air CO2 ∆’17O mainly governed by the isotope composition of local meteoric water. Additionally, CO2 from fossil fuel combustion processes shows a negative 17O-anomaly inherited from the isotope composition of atmospheric O2 [3].

Starting in April 2023, we conducted automated triple oxygen isotope measurements of air CO2 in Göttingen using tunable infrared laser direct absorption spectroscopy (TILDAS; Aerodyne, USA) coupled with a custom-built inlet system. The internal error of the ∆’17O measurements was < 10 ppm and of the δ18Omeasurements < 0.01‰.

In this report, we present our initial results and discuss the contribution of various reservoirs to the ∆’17O of atmospheric CO2 in Göttingen. We also examine daily and seasonal variations observed in our data.

An integrated mindfulness and physical exercise intervention: Evaluating the effects on school staff

Publisher: name: Loughborough University

Subjects: Business systems in context not elsewhere classified

description: This programme of work was designed to develop, implement and execute a granular evaluation of a workplace intervention delivered in the school context. The intervention taught mindfulness skills applied to cardiovascular physical exercise. A multiphase, mixed-methods, process and effect evaluation of an integrated Mindfulness Based Physical Exercise (MBPE) intervention was carried out in three schools. To trial intervention-fit, the two-stage programme started with a feasibility study in a pilot school. Stage one results informed the second study’s intervention design (timing and content of didactic input), and the research and implementation strategy (including revised exclusion criteria, approach to recruitment, and data collection methods). In the second stage the MBPE intervention, consisting of four classes, reflective activities, and home practice, was first delivered to an intervention group (n=14). Participants recorded observations about their experience of combining mindfulness with physical exercise through in-class reflection sheets and weekly journals. Wellbeing and resilience measures were completed pre-intervention (T1), post-intervention (T2) and at follow-up (T3). Process evaluation data were collected throughout. A second, wait-list comparison group (n=10) received a three-week intervention, with similar data collection streams. Group-level quantitative analysis showed significant results for wellbeing, but not for resilience. A person-specific quantitative analysis, used to assess impact across six measures, provided a more granular understanding of effect (three sub-groups emerged, of which two had at least one significant outcome effect). The process evaluation, including the use of template analysis for qualitative data, afforded rich and granular data, which helped to elucidate a positive perception of the intervention, a good fit to the school context, and support for the proposed synergistic benefits and mechanisms for change. This study makes three contributions. First, the research contributes to the small but growing corpus of literature focused on the combination of mindfulness with physical exercise. This study advocates the need for careful integration, proposing a framework of synergistic benefits. Next, the research provides a case study for the design, implementation and evaluation of complex workplace interventions, through a two-stage process evaluation design. This innovative design provides rich data, analysed at group-level, person-centred and person-specific levels, to examine heterogenous differences in how an integrated intervention works, and for whom. Finally, the study contributes to the theory and practice of workplace wellbeing through practical insights offered to improve the MBPE intervention, and to support implementation in both school and the wider workplace context.

description:
The role of clay colloids in facilitating or hampering the transport of cationic contaminants, such as heavy metal cations or radiogenic nuclides, in groundwater is well established. However, it is unclear whether this phenomenon occurs with positively charged organic contaminants to the same extent.

Laboratory column studies were conducted on water-saturated quartz sand for investigating the influence of colloids on the transport of metoprolol (MTP), a β-blocker with an acid dissociation constant (pKa) of 9.6, under varying pH and ionic strength conditions. The experiments were carried out at pH 3, 6, and 11, with sodium concentrations of 1 and 100 mmol L–1. Experiments were conducted with and without 0.5 g L–1 Na-montmorillonite colloids (diameter: 100–1000 nm). The results show that the presence of colloids increases the transport velocity of MTP, particularly at pH 6 and low sodium concentrations, indicating colloid-facilitated transport as the primary mechanism. Upon reducing the pH, the magnitude of colloid-facilitated transport decreases, but the bimodal breakthrough curve still suggests some co-transport of MTP. At pH 6 and high sodium concentration (100 mmol L–1) and pH 11, where MTP is predominantly uncharged, the presence of montmorillonite did not significantly impact the transport of MTP.

These findings highlight the dependence of MTP transport on the existence of clay colloids, salt concentrations, and the speciation of the contaminant determined by water pH. Thus, considering these variables is crucial for accurately predicting the mobility of positively charged organic contaminants in groundwater.

description:
Seasonal ATES systems enable the efficient integration of climate-neutral heat sources into urban heat-supply systems. However, secure and efficient operation presupposes the detection as well as realistic evaluation and prediction of induced hydraulic, thermal, geochemical and microbial effects and their impacts on operation and environment.

To provide the database for extending field-scale process understanding and deriving suitable monitoring strategies, a cyclic HT-ATES field test was conducted. In six fortnight-long charging periods ~300 m³ of water were infiltrated (~15 L/min; ~80 °C) into the storage aquifer (6-15 bgs) and recovered directly or after 21 storage days. Induced hydrogeochemical effects and their reversibility were tracked with a temporal and spatially high-resolute monitoring of ~90 measurement points.

Within ~7 m around the „hot well“, superimposition of formerly stratified calcium and sulphate concentrations in combination with the spatial spreading-patterns of elevated silica concentrations point towards the build-up of a density-driven convection cell, which was also predicted by accompanying numerical thermo-hydraulic simulations. In storage periods, but more so in post operation, decreases in temperature go along with a decline of previously elevated concentrations of e.g. silica, potassium, selenium and vanadium. Moreover, potassium and selenium concentration-peaks drop after the first cycles, indicating depletion of their releasable pools. Although simulated tracers indicate passage of infiltrated water, no induced temperature or concentration changes were monitored 30 m downstream so far.

Overall, highly dynamic flow conditions dominate the hot well’s vicinity and despite scale dependent low heat recovery rates, reversibility of induced effects keeps the wider surrounding geochemically unaffected.

description:
Inverting forward models to constrain output against data is critical for predicting and understanding sedimentary systems. We present an open-source workflow using SciPy functions to invert a Python Badlands model with spatially variable tectonic and rainfall parameters.

Tectonic uplift and rainfall maps are input to model surface uplift, erosion, transport and sediment deposition across the model grid. A SciPy function optimises against an objective function to calculate error and invert the model to find the optimal tectonic and rainfall parameters required to reproduce key aspects of the observed strata.

The workflow has four steps:

Collate paleoDEM’s, paleogeographic, thermochronological and climatic data to create initial topography, tectonic uplift and rainfall input maps

Run the Badlands forward stratigraphic model to calculate evolving topography and basin-fill strata

Use an objective function to calculate error from the comparison of model output and observed stratal properties

Use SciPy to iteratively optimise parameters through steps 2 and 3 to minimize model error

This approach generates a useful series of best-fit models for the Bengal Fan source-to-sink system. The nature of the objective function reveals important aspects of the model behaviour and indicates that climatic factors increasing erosion and sediment yields were the main forcing of Miocene deep-water sedimentation in the Bengal Fan.

description:
The results of the application of the mobile direct-prospecting technology of frequency-resonance processing and interpretation of satellite images and photographs in large areas and local areas of hydrogen degassing in German various regions are presented. Experimental reconnaissance studies were carried out to study the features of the deep structure of hydrogen-degassing areas.

Instrumental measurements confirmed the presence of large zones of hydrogen degassing in the areas of basalt volcanoes in Bavaria. Signals at the frequencies of hydrogen, basalts and healing water were recorded at the sites performed for the hydrogen migration. Measurements recorded the facts of hydrogen migration into the atmosphere. When scanning the cross-section, responses from hydrogen are recorded from the upper edges of basaltic volcanoes to their roots. Signals at hydrogen frequencies were also recorded from limestones, dolomites, and marls overlying the basalts from above (including at shallow depths). Experimental studies have also shown that siliceous rocks can be a good seal for hydrogen. There is no hydrogen migration into the atmosphere within basalts, overlapped by siliceous rocks. The obtained results of experimental work are also additional evidence in favour of the "volcanic" model of the formation of various structural elements and the external appearance of the Earth, as well as deposits of combustible and ore minerals (including hydrogen and water).

The use of mobile and low-cost technology will significantly speed up the exploration process for hydrogen, as well as reduce the financial costs for its implementation.

description:
The assessment of seismic hazard and potential earthquake secondary effects such as tsunamis in offshore environments requires, similar to onshore environments, a good knowledge of the subsurface shear-wave velocity (Vs) distribution with depth. Between 2018 and 2020, a seismological campaign with Ocean Bottom Seismometers (OBS) was performed on selected subaqueous slopes with unconsolidated sediment cover in Lake Lucerne (Switzerland) to measure ambient vibrations and to monitore earthquakes. OBS were deployed in the single station and array configurations. First, we use the single station ambient vibration data to estimate the microtremor horizontal-to-vertical (H/V) spectral ratio. Second, we follow a robust preprocessing workflow to extract the phase velocity dispersion curves (DC) from OBS ambient vibration array measurements. The estimated H/V spectral ratios and the DC are used as targets in an inversion process for the Vs profile determination. The microtremor H/V spectral ratio forward modelling routine uses a new model that is based on the seismic interferometry principles under the diffuse field assumption and considers the presence of the water layer.

description:
The current challenges in our society regarding digital, energy, and circular economy transition have made the recycling and recovery of materials from waste streams a hot topic since they have the potential to provide part of the materials required to meet the challenges. Evaluating the sustainability of a project is also crucial, which usually involves a number of requirements for the project. In this regard, the classification of projects is key to the development of secondary raw materials (SRMs) recovery and recycling projects, including their proper management. The United Nations Framework Classification for Resources (UNFC) is a unique tool to assess all types of resources on the same principle notably projects related to the supply of Critical Raw Materials and SRMs from primary and anthropogenic resources. It considers the level of confidence in the quantity of products obtained, their technical feasibility, and their environmental-social-economic viability. Hence, it can be used as a decision-support tool on company, regional, and national levels.

This paper presents a web-based tool developed for the assessment of SRMs to determine, among other things, the maturity level of SRM recovery projects in accordance with the UNFC. The development process of the web-based tool will be discussed, including its design, features, and functionalities. An example is provided to show how the tool can be used to assess different types of secondary raw materials, highlighting its potential benefits for the circular economy.

description:
During expedition MSM109 in July 2022, a new hydrothermal vent field was discovered, which is the first active field found along the 500-km-long ultra-slow spreading Knipovich Ridge. The so-called Jøtul hydrothermal field is not located on an axial volcanic ridge (AVR) but is associated with the eastern bounding fault of the rift valley. A hydrothermal plume with methane concentrations between 100-1000 nmol/L emits hot fluids into the water column above the hydrothermal field, and is being drifted north with the bottom current. These high methane emissions are likely related to interactions between magmatic intrusions and sediments of the Svalbard continental slope produce unusually high release of thermogenic methane. Further investigations during MSM109 using ROV Quest show a wide variety of fluid escape sites such as diffusive venting from sediments, as well as seepage from joints and cracks within igneous rocks. Additionally, new inactive and active mounds with abundant hydrothermal precipitates and chemosynthetic organisms were discovered. Fluids were sampled from an active black smoker emitting fluids with temperatures > 316°C, and from three other sites with venting temperatures between 8°C and 272°C. The fluids are characterized by high methane, carbon dioxide, and ammonium concentrations, as well as high 87Sr/86Sr isotope ratios, indicating a strong interaction of the fluids with sediments from the continental margin of Svalbard. Locations with such intense magma/sediment interactions are of particular importance for the carbon cycle, and a focus of the Bremen Cluster of Excellence "The Ocean Floor – Earth’s Uncharted Interface".

description:
The sediment-hosted Spremberg-Graustein-Schleife deposit is located in Lusatia, eastern Germany. Mineralization occurs in the lower Zechstein units, extending from the Grauliegend conglomerates and sandstones into the overlying organic-rich Kupferschiefer black shales and Zechstein carbonates. Around 100 Mt of Cu-Ag ore is present within the deposit. The ore is also enriched in Pb, Zn, Co, Ni, Au, Bi, Se, Re, and Ge (in addition to Cu and Ag). Despite the metal endowment, detailed quantitative metal deportment studies have not been carried out for this deposit, or indeed any other Kupferschiefer deposit. This study aims to bridge the gap. Core samples representing the complete mineralization interval (31 m in total) at three different sites within the deposit were mineralogically and geochemically analyzed. To ensure a comprehensive, high-quality and internally consistent dataset, various analytical methods including X-ray fluorescence (XRF), ICP-OES, ICP-MS, X-ray diffraction (XRD), Mineral Liberation Analysis (MLA), electron probe micro-analysis (EPMA) and laser ablation ICP-MS (LA-ICP-MS) were performed. The results reveal that the concentration and main hosts of copper and potential by-products vary vertically between the stratigraphical units, and spatially at different locations of the deposit. Such information will eventually help to predict deportments across the deposit, track each element within the minerals processing plants and also to get an idea of expected recoveries and thus optimizing the procedure.

Slab fluids, which are released by the subducting oceanic lithosphere through compaction and dehydration processes, are an essential mechanism for the transfer of volatiles from the slab to the mantle wedge. However, migration processes of slab dehydration fluids are not well understood yet, particularly with regards to transport mechanisms of redox sensitive elements such as sulfur.

In this study we investigated an eclogite-facies metabasalt from the South Tianshan Orogen, NW China, which contains several omphacite-dominated HP veins. Using mineral chemical analyses combined with in situ δ34S measurements of pyrite, as well as isotope analyses of C, O, Sr and Pb in mineral and vein separates, we determined the metamorphic evolution of the studied sample and the speciation of sulfur during fluid infiltration and transfer.

Mineral chemical and isotopic compositions reveal seafloor alteration, affecting the protolith pillow basalt prior to subduction. This was followed by a two stage intra-slab fluid-flow under peak to prograde metamorphic conditions, forming the omphacite-dominated HP-veins. The first HP fluid originated from dehydrating ocean floor basalts, as documented by MORB-like pyrite δ34S signatures. The second HP fluid composition suggests, instead, an origin from the basalt-sediment transition with negative pyrite δ34S values of about -10‰. Pathways formed by the first fluid were reused and enlarged by the second fluid, which however also formed new pathways. This sample provides detailed insights into intra-slab fluid flow and fluid-rock-interaction processes at HP/LT metamorphic conditions and allows a better understanding of fluid transfer and sulfur speciation in subduction zones.

Groundwater temperatures (GWTs) vary based on the local geothermal heat flux, the energy budget at the surface, and land cover. With subsurface temperature data being scarce, standard techniques for the spatial interpolation often produce unrealistic representation of shallow GWT. It has been shown that utilizing remote sensing data can reproduce shallow GWT at an error of roughly 1 K. In our contribution, we apply such a technique to the state of Saxony-Anhalt, Germany. The estimation is trained and validated with a set of over 600 observation wells. The data used comprises data from the Landesbetrieb für Hochwasserschutz und Wasserwirtschaft Sachsen-Anhalt (LHW) as well as own monitoring campaigns for the cities of Magdeburg, Halle (Saale), and Dessau. Together with different satellite datasets, such as land surface temperature and building density, we use this measured GWT data to derive spatially resolved estimated GWTs (eGWT) for Saxony-Anhalt. The measured and estimated GWTs are then correlated to the land cover at the location. Thus, this study aims to (1) present measured GWT and eGWT distribution for Saxony-Anhalt, (2) assess the application of satellite data for estimating shallow GWT, and (3) research the correlation between GWT/eGWT and land cover.

The Global Time Scale of the International Commission on Stratigraphy includes subdivisions of systems down to stages but substages can be recognized once all stages are ratified. Devonian substage progress slowed down since the inevitable Pragian/Emsian boundary revision has not yet been achieved. Formal substage definitions are urgent since variable versions are used widely, in different regions, and by different authors. This hampers the precise correlation of climatic changes, sea-level fluctuations, geochemical cycles, rates of evolution, and extinction/radiation events. Precise and unequivocal time-scales are the pre-condition for advances in multidisciplinary Earth System research and geological mapping. Our recent studies led to progress in the case of Givetian to Tournaisian substages, which all shall be placed close to 2nd/3rd order global events, which importance is often hidden by their timing within stages.

The future Upper Givetian base shall be placed at the top of the global Taghanic Crises (base of hermanni Zone) while the Lower/Middle Frasnian boundary should coincide with the anoxic Middlesex Event. The best boundary marker, Ancyrodella nodosa, provides correlation with the Alamo Impact of Nevada. Revision of the controversial conodont scale at Martenberg, a potential GSSP, confirmed the semichatovae Transgression (nasuta Subzone) as the best Upper Frasnian base. Other Rhenish sections are suitable for the definitions of the Middle (base marginifera Zone, Beringhauser Tunnel), Upper (Lower Annulata Event, Effenberg), and Uppermost Famennian (e.g. Oese, base ultimus ultimus Zone). The anoxic Lower Alum Shale (base crenulata Zone) should re-define a Middle Tournaisian substage following the classical Belgium chronostratigraphic scale.

The short-lived isotope systems 146Sm-142Nd and 182Hf-182W were active during the first ca. 500 Ma and 50 Ma after solar system formation. As a result of recent analytical advances, it is now possible to detect small 142Nd-182W variations (≤ 3ppm) within terrestrial samples providing unprecedented information on Earth’s accretion, early differentiation, as well as mantle mixing and homogenization rates.

Here, we present high precision 142Nd/144Nd and 182W/184W data for Neoarchean samples from the Yilgarn Craton, W-Australia, using previously published MC ICP-MS protocols [1,2]. We report µ142Nd deficits as low as -4.2 ± 1.4 for 2.7 Ga mafic-ultramafic samples from the Kalgoorlie Terrane. A contemporaneous mafic-ultramafic suite from the Kambalda area displays small µ142Nd values between +0.4 ± 1.2 to -1.5 ± 0.9 that seem to correlate positively with ε143Nd. If interpreted to represent a differentiation model age, this event could not have happened earlier than 4.13 Ga. This suite reveals a correlation of long-lived ε143Nd-ε176Hf isotope systematics, suggestive of a pristine mantle source. We further suggest that µ182W excesses from the Kalgoorlie and Kambalda suites (+5.3 ± 3.6 and +4.5 ± 1.6) demonstrate a missing late veneer component in the mantle source, in line with previously reported ε100Ru excesses found in the same samples [3]. In conclusion, our results demonstrate that mantle-derived rocks from the Yilgarn Craton carry isotope signatures directly referring to Hadean processes.
