description:
The scarcity of well-preserved exposed Precambrian rocks as well as post-emplacement metamorphism and alteration hamper a detailed understanding of mantle differentiation processes on the early Earth. This issue can be overcome by powerful tools such as the short-lived isotope decay series such as 182Hf-182W and 146Sm-142Nd isotope systems that only record radiogenic ingrowth during the Hadean Eon.

This study focuses on high-precision measurements of 182W/184W and142Nd/144Nd isotope compositions using MC-ICP-MS ([1], [2]) of ultramafic, mafic and felsic rocks from the Singhbhum Craton (India) that range in their crystallization age from 3.5 to 1.6 Ga. Due to the susceptibility of W to secondary fluid-rock interactions, the rock samples that were chosen were initially tested for mobility of W by a comparison of W with other equally incompatible elements such as Th, Ta, U [3] that were obtained by  ICP-MS with a focus on precise measurements of High Field Strength Element concentrations (<6% uncertainty). Preliminary 182W isotope data that ranges from µ182W= -1.6 to -0.7 (±2-3 ppm; 95% CI) shows a slight tendency to negative values that are unresolvable from the modern mantle value.  This data, in combination with robust 142Nd isotope constraints can give fresh insights into early mantle differentiation of the Singhbhum Craton and access the timescales of homogenization of the ambient mantle with late accreted material.

Theory and algorithms for spatial transcriptomics denoising
Creators: name: Kubal, Sharvaj
Publisher: name: University of British Columbia
Year: 2023

description: Spatial transcriptomics goes one step beyond single-cell RNA sequencing, yielding high-dimensional images of gene expression in a tissue, which offer the prospect of understanding cell signaling. Recent breakthroughs in spatial transcriptomics have drastically increased the area of tissue which can be profiled. However, sequencing all RNA molecules over large spatial areas is prohibitively expensive. One would like to reduce the number of RNAs sequenced, but this results in excessive technical noise in the measured gene expression data. To counter this problem, we develop theory and algorithms for spatial transcriptomics denoising, based on low rank matrix recovery and spatial smoothing. We propose two novel procedures for estimating the true underlying gene expression image: (1) a low rank maximum-likelihood-type estimator with graph-based total variation regularization, and (2) a switching procedure that switches between 'risky' estimators that work well in practice, and 'safe' estimators which have well-known properties. Our methods are backed by theoretical recovery guarantees, as well as tests on real data which suggest that it is possible to reduce the number of RNAs sequenced by more than 10-fold, without significantly increasing recovery error. Finally, as a generalization of the analysis employed above, we establish some convergence rates for the estimation of structured discrete probability distributions.

description:
Carbonatites are mantle-derived igneous rocks which may comprise economically important mineralizations of REE and HFSE. Their emplacement into the crust is usually accompanied by fenitization, alkali metasomatism of country rocks caused by fluids expelled during cooling and crystallization. Often, carbonatites are associated with diverse silicate rocks like syenites, nepheline syenites or phonolites. Understanding magmatic differentiation and late-stage processes after emplacement, such as hydrothermal alteration and element remobilization and re-precipitation, is of great importance to understand the formation of HFSE and especially REE deposits.

Carbonatites and associated silicate rocks (syenites, phonolites, fenites) of the Kalkfeld group in Northern Namibia show a large range in whole-rock REE contents, heterogeneity and textural variety and are therefore perfectly suited to study the phenomena named above. Detailed petrographic and microtextural analysis of the samples was done and focused on understanding the paragenetic sequence and evolution of the samples. Within the carbonatites, the typical sequence sövite -> beforsite -> ferrocarbonatite is observed, as well as late-stage, hydrothermal mineralization of REE- bearing phases like ancylite and bastnäsite. Currently, the study focuses on mineral chemistry by means of EMPA to further differentiate processes involved in the formation and evolution of the observed assemblages. Furthermore, silicate minerals like pyroxene, biotite and feldspar observed in carbonatites of the Kalkfeld group may indicate wall-rock interaction and crustal contamination of the carbonatitic magma during ascent and emplacement. The importance of silica contamination on REE enrichment in the carbonatites of Kalkfeld group will be discussed.

description:
The Kuboos-Bremen Line (KBL) is an alignment of intrusions that extent for 250 km in South Africa and Namibia. Its deepest exposed parts occur near Alexander Bay (RSA) and it continues into the continent trending SW-NE, with the higher intrusion level at the Great Karas Mountains (NAM).

The KBL complexes are divided in three sections: Western KBL is predominantly granitic; Central KBL is composed of granites, syenites, foid-syenites and carbonatites; and Eastern KBL is composed of a field of more than a hundred small carbonate-bearing intrusions (carbonatite dykes, sills and breccia pipes, and lamprophyre and alnöite dyke swarms).

The project aims to understand the genetic relationship between the variety of lithologies at the KBL by: investigating whether the behavior of HFSE and REE in carbonatitic magmas is influenced by source contamination and silicate wall-rock interaction; investigating the cross-cutting relationships of individual complexes and their age data, to understand the progressive evolution from granitic to foid-syenitic/carbonatitic compositions with time and location; and study the rock associations to establish if different magma suites derived from one or variable sources and also if they used the same zone of weakness for ascent and emplacement.

After field work and sample collection from all main complexes the first results from geological mapping and petrography show an even broader variety of lithologies than expected. Individual units from individual complexes share textural and mineralogical similarities and also provide us hints of the role of crustal assimilation in the genesis and magmatic to hydrothermal evolution of these rocks.

description: The evaluation and verification of landscape evolution models (LEMs) has long been limited by a lack of suitable observational data and statistical measures which can fully capture the complexity of landscape changes. This lack of data limits the use of objective function based evaluation prolific in other modelling fields, and restricts the application of sensitivity analyses in the models and the consequent assessment of model uncertainties. To overcome this deficiency, a novel model function approach has been developed, with each model function representing an aspect of model behaviour, which allows for the application of sensitivity analyses. The model function approach is used to assess the relative sensitivity of the CAESAR-Lisflood LEM to a set of model parameters by applying the Morris method sensitivity analysis for two contrasting catchments. The test revealed that the model was most sensitive to the choice of the sediment transport formula for both catchments, and that each parameter influenced model behaviours differently, with model functions relating to internal geomorphic changes responding in a different way to those relating to the sediment yields from the catchment outlet. The model functions proved useful for providing a way of evaluating the sensitivity of LEMs in the absence of data and methods for an objective function approach.

description:
Geological storage of CO2 contributes to mitigating climate change, but successful storage depends on many subsurface hydrodynamic and geomechanical factors. This study outlines the development of a CO2 injection strategy for a potential multi-trap storage site in the German North Sea by jointly honouring the geomechanics as well as hydrodynamic and geological constraints. The site comprises three structural closures, each covering an area of tens of km2. Based on site-specific geology and petrophysical data, static storage capacities of the individual closures as well as the closure combinations are estimated. Each closure has a distinct configuration and drainage area, resulting in different CO2 phase dynamics in the subsurface, due to a different interplay of gravity, capillary and viscous forces. A 3D reservoir model is developed and used to simulate CO2 injection with a rate of 10 Mt/a over 30 years, followed by a 100-year post-injection phase, while accounting for the regional hydraulic boundaries. The allowable pressure limit is derived using dedicated geomechanical simulations. The individual settings of each closure result in varying depths and injectivities, which lead to different numbers of injection wells and their placement due to well interaction. Furthermore, pressure accumulation occurs depending on the relative position of the closure to the hydraulic boundaries, reducing achievable capacity. Consequently, injection well planning and optimisation efforts should prioritise settings that demonstrate high injectivity, high achievable storage capacity and a high allowable pressure window.

description: Botulinum neurotoxins (BoNTs) are potent neurotoxins produced by bacteria, which inhibit neurotransmitter release, specifically in their physiological target known as motor neurons (MNs). For the potency assessment of BoNTs produced for treatment in traditional and aesthetic medicine, the mouse lethality assay is still used by the majority of manufacturers, which is ethically questionable in terms of the 3Rs principle. In this study, MNs were differentiated from human induced pluripotent stem cells based on three published protocols. The resulting cell populations were analyzed for their MN yield and their suitability for the potency assessment of BoNTs. MNs produce specific gangliosides and synaptic proteins, which are bound by BoNTs in order to be taken up by receptor-mediated endocytosis, which is followed by cleavage of specific soluble N-ethylmaleimide-sensitive-factor attachment receptor (SNARE) proteins required for neurotransmitter release. The presence of receptors and substrates for all BoNT serotypes was demonstrated in MNs generated in vitro. In particular, the MN differentiation protocol based on Du et al. yielded high numbers of MNs in a short amount of time with high expression of BoNT receptors and targets. The resulting cells are more sensitive to BoNT/A1 than the commonly used neuroblastoma cell line SiMa. MNs are, therefore, an ideal tool for being combined with already established detection methods.

description:
Higher temperatures and increasing droughts are likely to lead to a reduction in available water resources in the Berlin-Brandenburg region. Concurrently, there is an increasing demand for water due to the population and economic development in the region. This results in serious water management challenges. To mitigate this water scarcity, in 2021, work began on setting up a coordinated joint groundwater management system based on a transboundary groundwater flow model for the capital region (approx. 2800 km², from which Berlin covers 892 km²). The central component is the modelling of the reciprocal effects of the groundwater abstraction by the water suppliers in the region with regard to sustainable management of the common groundwater body. In the first step, the hydrogeological structural model (HSM) for the region is created. In doing so, up-to-date geological sections from the Berlin and Brandenburg Geological Surveys as well as stratigraphical settings from existing calibrated groundwater models are brought together. The groundwater models of the Berliner Wasserbetriebe are also incorporated in this process. These models have been developed since approximately 20 years and are regularly updated. They are used both in approval processes and in daily operation. In the second step, the HSM is converted into a flow model. This flow model is calibrated and compared with the existing models. In the end, a model for the entire capital region will be available for the first time. At the conference, the current status of the project will be presented and the challenges will be highlighted.

Evaluating the effectiveness of a web-enabled psychoeducational intervention for postpartum mental health for women in British Columbia
Creators: name: Lawrence, Claire
Publisher: name: University of British Columbia
Year: 2023

description: Postpartum depression (PPD) and anxiety (PPA) affect about one-quarter (23%) of women in Canada. Despite this high prevalence, barriers exist making treatment inaccessible for many. Web-enabled resources are a promising solution, increasing access to mental health resources for women in the postpartum period. However, a patient-centered approach is not routinely taken in the development of web resources, leaving postpartum women out of critical decision-making processes. This study aimed to evaluate the effectiveness, usability, and user satisfaction of PostpartumCare.ca, a web-enabled psychoeducational resource for postpartum mental health, created in partnership with women in British Columbia (BC) affected by postpartum mental illness. Women experiencing PPD and/or PPA from BC who gave birth in the past 12 months were enrolled. Fifty-two were randomized to the intervention group (mean age 31.60 ± 5.12 years), receiving access to PostpartumCare.ca for four weeks, and 51 to a waitlist control group (mean age 34.25 ± 4.84 years). Participants completed measures evaluating PPD (Edinburgh Postnatal Depression Scale [EPDS]) and PPA (Perinatal Anxiety Screening Scale [PASS]) symptoms at baseline, after four weeks, and after a two-week follow-up. Intervention participants also completed measures of website usability and satisfaction after four weeks, and their website metrics were collected. PPD and PPA symptoms were significantly reduced for the intervention group following the use of PostpartumCare.ca, with improvements maintained after a two-week follow-up, corresponding with small-to-medium effect sizes (PPD: partial η² = .03; PPA: partial η² = .04). Intervention participants were also more likely than waitlist controls to recover from clinical levels of PPD symptoms. Overall satisfaction with PostpartumCare.ca was above average, with most reporting perceived changes in depressive and/or anxiety symptoms and endorsing the website’s technical adequacy, content quality, and appearance. Findings suggest that a web-enabled psychoeducational resource, created in collaboration with patient partners, can be effective in reducing symptoms of PPD and PPA, supporting its use as a low-barrier first-line option for women in BC experiencing postpartum mental health concerns.

description:
Highly saline lithium-rich hydrothermal fluids occur in the deep calcareous Muschelkalk aquifer of the northern Alpine foreland basin. We have combined geologic, hydraulic, hydrochemical, and stress field data of the Triassic Muschelkalk aquifer beneath sediments of the Molasse basin of SW-Germany for a synthesis to constrain the origin and development of these brines. In contrast to the regional southeast plunge of Mesozoic and Cenozoic strata, low gradient groundwater flow in the Upper Muschelkalk aquifer is to the north, induced by regional recharge from west, south, and east. North trending maximum horizontal stress axes might provide development of fracture permeability in the competent carbonates of the Upper Muschelkalk aquifer for northward flow. The highest lithium concentrations and total dissolved solids (TDS) can be found in the southeastern parts of the Muschelkalk aquifer, close to the Vindelician High, whereas during northward transport TDS and lithium concentrations are increasingly diluted. We argue that the highly saline lithium-rich fluids originate from fluid-rock interaction of meteoric water with Variscan crystalline basement rocks and entered the Muschelkalk aquifer by permeable faults and fractures. The marginal calcareous sand-rich facies of the Muschelkalk enables the inflow of brines from crystalline basement faults and fractures into the aquifer. We thus argue for an external origin of these brines into the aquifer. Potentials are considered as 100±25 t Li/yr per well.

description:
The Digermulen Peninsula in eastern Finnmark has attracted renewed research interest in recent years due to discoveries of new Ediacara-type fossils, marking the rise of macroscopic life on Earth. The entire upper Ediacaran and Cambrian sedimentary succession was considered to be siliciclastic. However, carbonates were discovered within the 2nd cycle of the Manndrapselva Member of the Stáhpogieddi Formation of the Vestertana Group (Meinhold et al., 2019, Precambrian Research, 328, 99-110). These carbonates occur as calcareous siliciclastic beds, lenses, and concretions, some with calcite spherulites and cone-in-cone calcite, in a mudrock to fine-grained sandstone succession approximately 40 m below the Ediacaran–Cambrian boundary. The calcite spherulites were probably formed at the sediment–water interface or a few centimetres below, either in a coastal littoral environment or in situ in the sublittoral zone under high alkaline conditions. In situ calcite U−Pb isotope data from an upper Ediacaran carbonate concretion provide timing constraints for depositional, diagenetic, and potentially metamorphic processes, overlapping and confirming previous estimates based on relative bracketing of events (Meinhold et al., 2020, Geological Magazine, 157, 1367-1372). The cone-in-cone calcite formed during burial diagenesis and clearly before low-grade metamorphism and cleavage formation, the latter being caused by the Scandian Orogeny.

description:
Eoarchean peridotites from the area south of the Isua Supracrustal Belt (SOISB) in southern West Greenland have been found by previous studies to contain sulfur subject to mass independent fractionation (MIF-S), with positive Δ33S values indicating that these rocks have incorporated sedimentary sulfur recycled from Earth’s surface [1]. New in-situ secondary ion mass spectrometry measurements of sulfide grains found within these peridotites reveal that this MIF-S is hosted within the sulfide grains. Electron microprobe analyses of the sulfide grains reveal that they are predominantly composed of pentlandite and pyrrhotite, consistent with the typical sulfide mineralogy of mantle rocks. The peridotites displaying the least petrographic evidence for melt overprint (Group 1) were found to contain the highest average in-situ Δ33S values, +0.20±0.02‰, while those bearing more evidence for melt overprint (Group 2) had lower average in-situ Δ33S values, +0.09±0.03‰. These findings are in good agreement with previous bulk rock S isotope results [1]. In-situ Pb isotope measurements of the sulfide grains reveal unradiogenic compositions consistent with an Archean origin. Furthermore, petrographic observations reveal that the sulfide grains are crosscut by amphiboles, indicating that the sulfide grains predate Neoarchean amphibolite-facies metamorphism. Our data support previous interpretations that these rocks are the oldest known mantle peridotites. These findings reinforce previous interpretations that SOISB peridotites preserve evidence of crustal recycling in the Eoarchean.

description:
The Halle Fault in central Germany is a major tectonic fault that separates the lower permian rocks (Rotliegend) in the north from triassic rocks in the south. While geological modeling of the Cenozoic and Mesozoic rocks on both sides of the fault has been carried out frequently in the last two decades, the Paleozoic volcanics and sediments of the Permo-Carboniferous rocks in the Halle-Wittenberg-Scholle that outcrop in the urban area have not been modeled in 3D. This study aims to fill this gap by proposing a 3D GIS-based modeling approach to model the geometric and stratigraphic relationship of the volcanic rocks and host-sediments of the Halle-Wittenberg-Scholle.

The approach relies on standard geological data, such as geological maps, boreholes, and digital terrain models, from which geological cross sections are generated and used for further modeling. Existing profiles and seismic data are desired and can bring advantages in the modeling process. While attempts to develop an open-source modeling tool have already been made, they require programming skills, making this GIS-based approach more accessible to a wider audience.

For this purpose this research aims to make the proposed method publicly available, enabling anyone to create a 3D geological model without the need for specialized and costly modeling programs. This approach facilitates an ideal exchange between students and scientists, promoting further understanding and exploration of the possibilities of geological 3D modeling, and also advancing the understanding of the geological features of the Halle Fault.

description:

Imaging the deep Earth structures is conventionally carried out using earthquake recordings. However, the resolving capability of such techniques (e.g., SS precursors and receiver function analysis) is often limited by the uneven spatial distribution of earthquake events and the high complexity of earthquake rupture processes. Recent advances in passive noise interferometry demonstrated the possibilities of recovering body waves from noise correlations, opening up new prospects for imaging the deep earth.

In this study, we map the mantle transition zone (MTZ) discontinuities beneath South- Central Europe using P-wave reflection phases recovered from noise correlations. We analyze up to four years of seismic noise recordings from 900 broadband stations in the study area. By stacking noise correlations in selected summer months, we significantly improved the retrieval of typically low-amplitude body-wave reflection phases in the light of a quiet surface-wave environment and sufficient noise body-wave illumination from deep paths. We obtain reliable P-wave reflections associated with the 410-km and 660-km discontinuities in the period band of 4-10 s. These short-period reflections reveal clear lateral depth variations of the two discontinuities, indicating a complex MTZ arrangement in the greater Alpine region that is related to both present and past tectonic regimes. Our imaging method shows its potential for general applications in studying deep-earth discontinuities.

description: Background: Humans are social and cultural beings. We all have racial, ethnic and social identities. It is thus crucial to integrate these into the practice of therapy and research. With the increasing rates of migration (and consequently diversity) all over the globe, multicultural society is likely to be a rule rather than an exception. This diversity will also reflect in the clinician’s offices, necessitating future clinicians to be multiculturally competent. Multicultural competence comprises of clinicians’ knowledge of their own cultural background, perceived notions and biases; clinicians’ efforts to understand and validate the worldviews of clients from different backgrounds; and clinicians’ skills to engage in culturally appropriate and sensitive therapy and assessments. Objectives: This research aimed to investigate the dimensionality of multicultural competence as there is some confusion in the literature. This was followed by adapting a precise scale based on items from previous measures using item response theory for measurement precision. Method: A sample of 165 graduate students in clinical, counselling psychology and social work programs were recruited. The data was collected primarily from North America and India. A scale for checking socially desirable responding was also included. Dimensionality analysis and item response theory were used to assess the psychometric properties of the existing multicultural competence scales. Network Analysis and exploratory factor analysis were then used to identify item clusters in order to derive the items for the new brief scale. Item response theory was conducted on this new scale with three factors. Implications: This research helps further our understanding of the dimensionality of multicultural self-efficacy and suggests pools of items that provide more precise measurement of the construct based on modern psychometrics.

description:
We conducted the first study on Ga-Al systematics in Archaean and Palaeoproterozoic banded iron formations (BIFs). Adjacent Fe oxide, metachert and mixed-type bands were analysed comparatively with solution-based SF-ICP-MS and ICP-MS/MS and laser-ablation SF-ICP-MS on nano-particulate pressed powder tablets and polished sections. Furthermore, we conducted a matrix-matched two-component mixing experiment with the BIF reference material IF-G and pure synthetic quartz sand. Results of the three comparative analytical procedures and the two-component mixing experiment assure a high quality of our analytical data even in the trace metal-poorest (meta)chert samples. Furthermore, the results suggest that finely dispersed Fe oxide particles dominate the Ga and Al content in BIF (meta)chert bands. Regardless of the samples' mineralogy, the Ga/Al ratios of BIFs range between 2×10-4 and 1×10-3. A compilation of Ga/Al ratios in the investigated samples throughout time shows that during Precambrian global marine Ga/Al ratios were most likely rather constant. The BIF Ga/Al ratios are above those of potential detritus but below those of modern seawater. Two conclusions are conceivable: (i) Precambrian seawaters had lower Ga/Al ratios than modern seawater, possibly due to the reduced importance of organisms and organic compounds during weathering, riverine and estuarine processes. (ii) Ga and Al were fractionated during BIF formation, and BIFs did not preserve the original seawater Ga/Al ratios.

description: Op de Open Monumentendagen van 2006 en 2007 werd de site opengesteld voor het publiek. Roland Swaenepoel legde bij die gelegenheid een wandelpaadje aan tussen en rond de funderingen. In de beschrijving en interpretaties van de diverse onderdelen van de grondvesten volgen we het wandelpad. De bezoekers die toen een gidsbeurt volgden, zullen zich wellicht de opeenvolging van de verschillende compartimenten herinneren. De nummering van 1 tot 8 op het grondplan stemt eveneens overeen met deze volgorde. Zodoende respecteren we tegelijk de chronologie bij het opgraven van de diverse onderdelen. Op 22 juli 2006 werd de opgraving gestart met kraanwerken.

description:
The KSP Complex in the Eastern Alps is a lithologically heterogenous (U)HP nappe with eclogite lenses embedded in gneisses and metasediments. The formation history of the KSP Complex is still debated. Here, we investigate in detail the pressure and temperature conditions during the formation of the complex along a NW-SE transect following the direction of subduction. This is the first study where quartz inclusions in garnet elastic barometry was conducted to determine the entrapment pressures, which correspond to the minimum pressure conditions present during the entrapment of quartz inside garnet. The eclogites yield pressures of max. 1.9 GPa across the KSP complex, indicating no pressure increase from the NW to SE. The metasediments and gneisses show overall lower pressures with ca. 1.4 GPa. Temperatures based on Zr-in-rutile thermometry do not indicate a temperature increase from NW to SE, with ca. 640 (±30)°C across the whole KSP Complex, based on very similar Zr content of ca. 270 ppm. U/Pb dating on garnets in metasediments provide the following ages for the Koralpe 101.3 ± 6.6 Ma (throughout garnet); Saualpe 224.6 ± 31 Ma (core) and 95.43 ± 5.6 Ma (rim); Pohorje 99.83 ± 5.85 to 104.2 ± 7.1 Ma (throughout garnet). Garnet in eclogite from Koralpe is 112.8 ± 9.9 Ma. Combined with results of previous studies of eclogite ages, we suggest, that the eclogites are former (probably Permian) gabbro intrusions that experienced HP conditions during the Eo-Alpine orogeny. Whereas garnet ages of metasediments from Saualpe provide evidence for a polymetamorphic history.

title: Shaping the northern Gondwana margin before the Variscan orogeny: large-scale geodynamic processes and paleogeography

description:
The Cadomian accretionary orogeny at the end of Neproterozoic to early Cambrian was one of the principal crustal growth events in Europe, as indicated by a number and widespread distribution of Cadomian basement units within the Variscan and Alpine orogenic belts. Although the evolution of the Avalonian–Cadomian active-margin of northern Gondwana has been well established, geodynamic causes of its collapse and processes of its transition to a passive margin are significantly less understood. The particularly intriguing issues, which have a significant impact on interpretations of paleogeography and course of the subsequent Variscan orogeny, include: (1) how and when the Cadomian orogeny ended, (2) what was the provenance of the Avalonian, Cadomian, and other terranes, i.e., where they started their journey from Gondwana to Pangea, (3) how was the Cambro–Ordovician rifting phase expressed along the former active margin and what was its exact timing, duration, style, and magnitude, and (4) how far east reached the Rheic Ocean rift system and what was the nature of its eastern termination. Integrated geochronological and tectonic information suggest that (i) the active-to-passive-margin transition was step-wise, protracted over Cambrian and early Ordovician, (ii) strongly controlled by tectonic inheritance whereby an inherited suture in the Avalonian ribbon terrane facilitated complete rifting and rift–drift transition while the Cadomian terranes remained attached to Gondwana, and (iii) magmatism may have been an important geodynamic driver of rifting during at least the initial stages, before being overridden by the slab pull force of the subducting Iapetus Ocean.

description:
Here we present published and new age data of plutonic and volcanic rocks from Saxothuringia obtained by the high-precision CA-ID-TIMS U-Pb zircon dating method. This method has an uncertainty of ca. 0.1-0.2 % (corresponding to < ± 0.5 Ma) that is ca. 10 times smaller than all other recently established dating methods. Consequently, the application of this method allows better establish the exact sequence of magmatic processes in time and space. We show that magmatism in the Erzgebirge and in the Lausitz mainly occurred during two larger magmatic phases and that volcanic rocks first appeared in the Eastern Erzgebirge. We present also dating results from several volcano-sedimentary basins in Saxothuringia that allows a better comparison of their temporal evolution.
