title: Experimental data on free swelling potential of clayey soils

description: We present experimental data on vertical swelling potential of natural and artificial clayey soils obtained from different regions across the world. The swelling data and the relevant soil properties were acquired from studies that employed standard soil testing techniques and followed recommended procedures to measure vertical one-dimensional swelling potential of the soil samples. In total, the dataset contains 518 soil swelling potential data points covering a wide range of properties/conditions relevant to field applications. The corresponding soil properties are the activity, water content, dry unit weight, liquid limit, plastic limit, plasticity index, and clay content. The dataset presented is of interest of geotechnical engineers and researchers dealing with expansive soils, and provides insights on the influences of various soil’s characteristics on swelling potential natural and artificial clayey soils.

title: Zircon U-Pb Geochronology and Trace/Rare Earth Element Geochemistry from the Cordillera Blanca batholith and Huayllapa Pluton, Peruvian Andes

description: This collection presents paired U-Pb and Trace/Rare Earth Element geochemistry from zircons from four samples traversing the N - S exposures of the Cordillera Blanca batholith and from two samples of a previously unnamed pluton near the village of Huayllapa, Lima, Peru (the Huayllapa Pluton). Samples from the Cordillera Blanca batholith are granodiorite, specifically leucogranodiorite. Samples from the Huayllapa pluton are granodiorite and tonalite. Geochronology data in this collection include zircon U concentrations, 206Pb/204Pb ratios, U/Th ratios, 206Pb/207Pb ratios, 207Pb/235U ratios, 206Pb/238U ratios, percent error on isotope ratios, error correlation coefficients, 206Pb/238U dates, 207Pb/235U dates, 206Pb/207Pb dates, and associated percent errors, and 2-sigma errors on 206Pb/238U dates. Based on the age of the samples (&lt;30 Ma), we recommend using 206Pb/238U dates and 2 sigma errors. Trace and rare earth chemistry reported in this collection include concentrations, in parts per million, for La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Y, Ho, Er, Tm, Yb, Lu, Hf, P, Th, U, and Nb. This data was collected to explore temporal and genetic connections between magmas in the Cordillera Blanca and the Cordillera Huayhuash, as well as to assess the origin of zircon date overdispersion in individual samples of the Cordillera Blanca batholith and implications of magmatism for the geodynamic evolution of the region. This dataset is intended to compliment a manuscript submitted for publication in Geosphere.

title: Raw SIMS depth profiling data from internally standardized diamond-like carbon Genesis solar wind collectors.

description: Raw bulk solar wind and implant standard data were collected as part of Rieck, 2015. Measurements were made in GENESIS mission diamond-like-carbon B/C collectors using a CAMECA IMS 7f-GEO SIMS in depth-profiling mode. The raw data provided in this dataset were used in Rieck et al. (accepted) to demonstrate how the combination of back-side depth profiling with back-side implanted internal standards aides quantification of shallow mono- and poly-isotopic implants. This technique helps mitigate matrix effects and keeps measurement conditions consistent.

title: Carbonate-associated sulfate concentrations and sulfur isotopic ratios for bivalves from Guadeloupe and the Mid-Atlantic Ridge.

description: A suite of modern bivalves including infaunal lucinids from mangrove and seagrass sediments in Guadeloupe, an epifaunal oyster from a mangrove in Guadeloupe, and an epifaunal mytilid from the Mid-Atlantic Ridge, were collected. The shells were sub-sampled by micro-drilling and analyzed for their carbonate-associated sulfate (CAS) concentrations and sulfur isotopic ratios. The purpose of this dataset is to assess whether chemosymbiosis with gill-dwelling sulfur-oxidizing microorganisms leaves a distinctive geochemical fingerprint in the CAS preserved in bivalve shells.

title: Sulfur isotopic composition of mineral-hosted sulfide inclusions from Tristan, Inaccessible, Nightingale and Gough island lavas

description: Sulfur isotopes were analyzed by SIMS on 47 sulfide inclusions, a total of 81 spot analyses, hosted in phenocrysts (olivine, clinopyroxene, plagioclase, Ti-magnetite or ilmenite) of basaltic rocks from Tristan Island group (6 samples from Tristan da Cunha, two from Inaccessible and one from Nightingale) and three samples from Gough Island. These islands represent the most recent activity of the major 130 Ma-long-lived EMI-type Tristan-Gough plume system with a root at the core-mantle boundary related to the African large low shear wave velocity province (LLSVP). Sulfur isotopes have emerged in the last few years as a promising tool to address questions of age and surface origin of mantle plume precursor material. The Archean/earliest Proterozoic is with &gt;2.45 billion years older than half the age of the Earth. Only during those early times when there was little oxygen in the atmosphere, sulfur was changed in the atmosphere by solar radiation, forming so-called mass-independently fractionated sulfur isotopic compositions (MIF-S) that then rained onto the oceanic plate and was subducted into the mantle. So when we measure MIF-S in mineral-hosted sulfide inclusions in volcanic rocks, it tells us that the magma formed from material that once resided at the surface of the Earth and that this surface material is older than 2.45 billion years.

title: High-precision trace-element data on olivine phenocrysts in lavas from Tristan-da-Cunha and Gough islands

description: High-precision trace-element data on olivine phenocrysts were measured in two lavas from Tristan-da-Cunha and three lavas from Gough Islands. Multiple olivines were analyzed from each sample – 22 from TDC58, 28 from TCC59, 37 from ALR52G, 25 from ALR12G and 23 from ALR10G. Tristan-da-Cunha and Gough islands represent the most recent activity of the major 130 Ma-long-lived enriched-mantle-1(EMI)-type Tristan-Gough plume system with a root at the core-mantle boundary related to the African large low shear wave velocity province (LLSVP). Olivine analyses allow to constrain the source mineralogy of the lavas distinguishing pyroxenite versus peridotite. With pyroxenite probably representing recycled oceanic crust and peridotite representing normal mantle these data allow to narrow down the possible precursor material of this plume with geodynamic implications.

title: Pore water chemical composition and sediment mineral composition in different seepage intensities of Haima Cold Spring

description: Haima Cold Seep is located in the northern basin of the South China Sea and is an active cold seep. We selected four areas with different seepage intensities to collect gravity column samples at different intervals and extracted pore water to test the metal ions and anions. Sediment samples were also collected for power X-ray diffraction testing. Different methane seepage intensities affect the geochemical-biological processes in the sediments, which in turn lead to different characteristic pore fluid profiles and sediment mineral compositions

title: Well water and drill cuttings from north Punjab, Pakistan v.2

description: Updated dataset of 2710. Groundwater of the Ravi River floodplain is particularly elevated in arsenic (As) on both sides of the Pakistan-India border. To understand the origin of this pattern and generally lower groundwater As concentrations elsewhere in the Punjab plain, 14 new sites were drilled to 12-30 m depth across river floodplains and doabs of Pakistan in a subset of the 215 villages containing 20,348 wells that were tested across the region. Radiocarbon dating of clay cuttings from the Ravi floodplain indicates deposition of the underlying aquifer sands during the Pleistocene. Little if any Holocene accumulation is consistent with floodplain incision inferred from high-resolution elevation. A majority of the 132 samples of sand cuttings across the region were gray in color, indicating partial reduction to Fe(II) oxide coatings. However, as much as a third of the sand cuttings were orange in color, suggesting the prevalence of Fe(III) oxides and less reducing conditions. Associations between groundwater electrical conductivity, dissolved Fe, sulfate, and nitrate across tested villages in the region suggest that some wells are elevated (&gt;10 µg/L) in As due to reductive dissolution of Fe oxides and/or alkali desorption. In the Ravi floodplain, 47% of 6,445 wells tested are elevated in As relative to this threshold, however, compared to only 9% of 14,165 tested wells in doabs and floodplains other than the Ravi. We hypothesize that the oxidation of sulfides, possibly by nitrate, is responsible for elevated As in groundwater in the Ravi floodplain. The As content of aquifer sands outside the Ravi floodplain averages 2±2 mg/kg (n=51) and increases to 4±4 mg/kg (n=66) in the portion of the Ravi floodplain within Pakistan, and 6±7 mg/kg (n=99) upstream in India. Synchrotron spectroscopy and column-based speciation suggests that much of this more abundant As is present in sulfide minerals, and that the As that is evolved is arsenate. Regardless of the mechanisms at play, extreme lateral and vertical heterogeneity of As in well water could be taken advantage of to lower the exposure across the region with more testing and targeting of low As aquifers.

title: Deep ultra-hot melting residues as cradles of mantle diamond

description: The ancient stable continents are up to 250 km deep with roots extending into the diamond stability field. These cratons owe their mechanical strength to being cool and rigid, features inherited from extensive melt extraction. The most prominent model for craton formation envisages dominant melting at relatively shallow depth (50-100 km) above diamond stability followed by later imbrication to form the deeper roots. Here we present results from the first thermodynamic and geochemical modelling of melting at sufficiently high temperatures to produce the very magnesian olivine of cratonic roots. The new closed and open-system modelling reproduces the observed cratonic mantle mineral compositions by deep (c.200 km) and very hot melting (≥1,800°C), obviating the need for shallow melting and stacking. The modelled highly magnesian liquids (komatiites) evolve to Al-enriched and Ti-depleted as observed in the greenstone belts at the fossil surface of cratons. The paucity of Ti-depleted komatiite implies that advanced closed-system isochemical melting (&gt;1,825°C) was much less common than open-system interaction between deeper liquids and melting of existing refractory mantle. The highly refractory compositions of diamond inclusion minerals could imply preferential diamond growth in the more reducing parts of the cratonic root, depleted by ultra-hot melting in response to heat plumes from a deeper former boundary layer that vanished at the end of the Archaean.
