AndreaBozzo/ceres-open-data-index huggingface dataset:
Synthetic and experimental friction data processed with steadystate.m

This dataset contains raw data from synthetic and experimental velocity steps analyzed using the MATLAB routine ‘steadystate.m’, as presented by Giacomel, P., Faulkner, D.R., Lambert, V., Allen, M.J (2024): ‘steadystate: A MATLAB-based routine for determining steady-state friction conditions in the framework of rate- and state- friction analysis’ – GSA, Geosphere. The data is provided in .zip folder containing the Velocity Steps and the outputs from steadystate.m, along with the scripts used to generate the figures shown in the Manuscript and Supplementary Material. The folder ‘Velocity_Steps’ notably contains the complete suite of mechanical data (subfolder ‘Mechanical_Data), the modelled rate- and state- friction parameters (subfolder ‘Modelled_RSF_Parameters SlipLaw’) obtained by assuming steady state at different displacements, as well as the linear detrended end members (i.e., at short to large displacements) fitted via inverse modelling (subfolder ‘Detrended_Velocity_Steps + Fit-Inversions’). Such observations were foundational for the development of the steadystate.m routine. Each subfolder is accompanied by a README.txt file that reports on the link between the raw .txt data with the MATLAB scripts generating the associated figures. For the sepiolite fault gouge used during the friction velocity steps, please refer to: Sánchez-Roa, C., Jiménez-Millán, J., Abad, I., Faulkner, D. R., Nieto, F., and García-Tortosa, F. J., 2016, Fibrous clay mineral authigenesis induced by fluid-rock interaction in the Galera fault zone (Betic Cordillera, SE Spain) and its influence on fault gouge frictional properties: Applied Clay Science, v. 134, p. 275-288.

Spatial and temporal datasets for 11 different small-scale laboratory experiments of fluid-driven fractures

These data consist of spatial and temporal datasets for 11 different small-scale laboratory experiments of fluid-driven fractures, described in the paper Up, down, and round again: the circulating flow dynamics of flux-driven fractures (Chalk and Kavanagh, accepted in Physics of Fluids, February 2024). These experiments, conducted at the University of Liverpool, are analogue models of natural fluid-driven fractures in glacial and magmatic settings. Fractures were created by injecting water or silicone oil into transparent gelatine at a constant rate. The total experimental data set consists of 11 different experiments named: S1,S2,S3,S4,S5,W1,W2,W3,W4,SH,WH. S experiments involve the injection of silicone oil, and W experiments involve the injection of water. The raw data consist of a temporal series of jpegs from camera recordings of each experiment, located in the subdirectory "frames". For all experiments except for WH and SH, the data also consist of a temporal series of csv files containing spatial velocity data of the internal fluid flow, located in the subdirectory "PIV". These data are described in further detail in the metadata file in the raw data directory.

High precision zircon U-Pb data for plutonic rocks from the Masirah and Ra's Madrakah ophiolites, South East Oman

Zircon U-Pb isotope data are presented for eight plutonic rocks from the Masirah ophiolite and one plutonic rock from the Ra's Madrakah ophiolite (south east Oman). These data constrain the age of formation of the two ophiolite nappes exposed on Masirah Island (early Cretaceous), whereas two intrusions with younger ages (late Cretaceous) overlap with the proposed emplacement age of the ophiolite. The data cover two sites in the Masirah Lower Nappe, two sites in the Masirah Upper Nappe (on Masirah Island, off the SE coast of Oman) and one site on Ra's Madrakah (on the mainland of Oman). The interpretation and discussion of these data form part of a manuscript submitted to Geochemistry, Geophysics, Geosystems. Data collection was done using chemical abrasion isotope dilution thermal ionisation mass spectrometry (CA-ID-TIMS) at the NERC Isotope Geosciences Laboratories at the British geological Survey, supported by NERC Isotope Geosciences Facilities award IP-1919-0619. This work resulted from a PhD project funded by NERC GW4+ DTP grant NE/L002434/1.

The amino acid composition of 20 aragonite samples precipitated in vitro in the presence and absence of amino acid (aspartic acid and glycine, separately and in combination), the dipeptide glycyl-L-aspartic acid and tetra-aspartic acid.

Amino acid compositions of aragonite samples precipitated from seawater, using a pH stat titrator using the constant composition technique between September 2021 and December 2022. Samples were precipitated from 330 mL of seawater with no biomolecules (control) or with a seawater concentration of 2 mM of aspartic acid (Asp), 2 mM glycine (Gly), 2 mM of both amino acids (Asp+Gly) or 2 mM dipeptide glycyl-L-aspartic acid (Asp-Gly) or from 33 mL of seawater with variable concentrations of aspartic acid (Asp) or tetra-aspartic acid (Asp4). Protein was extracted from the samples and run as free amino acids (to detect amino acids in free form) and as hydrolysed samples (to detect peptides). Data were collected to determine how changes in the calcification fluids of calcareous organisms affect aragonite precipitation. Data were collected by Giacomo Gardella, Sam Presslee and Nicola Allison and interpreted by Giacomo Gardella, Cristina Castillo Alvarez, Nicola Allison, Adrian Finch, Kirsty Penkman, Roland Krӧger, Sam Presslee and Matthieu Clog

Nitrogen geochemistry of igneous units from Loch Doon, Scotland (NERC Grant NE/P012167/1)

This dataset contains the nitrogen, oxygen, and lithophile element geochemistry of whole rock, and distribution coefficients, and stable isotope fractionation factors for biotite, orthoclase, and plagioclase mineral separates from the Loch Doon Zoned Pluton, Scotland. The samples were collected from the northern limb of the Loch Doon pluton and are petrologically classified as are granodiorites and granites which show geochemical evidence for being a cogenetic zoned pluton. The data were collected over a time period of 2019-2022. These data were collected to investigate elemental partitioning and stable isotope fractionation of nitrogen between biotite, plagioclase, and orthoclase relative to each other and to the system (whole rock) during magmatic differentiation. This project was curiosity-driven science, and the anticipated interest groups are assumed to be the wider research community via scholarship and analytical protocols. These data were collected by an international team of scientists as part of Dr Toby Boocock’s PhD project. The full list of contributors are shown below: Boocock, TJ., Stüeken, ES., König, R., Mikhail, S, The University of St Andrews, UK (performed analysis, acquired samples, interpreted data) Bybee, GM, The University of the Witwatersrand, South Africa (performed analysis) Boyce, AJ, Scottish Universities Environmental Research Centre, UK (performed analysis) Prytulak, J, Durham University, UK (interpreted data) Buisman, I, University of Cambridge, UK (performed analysis)

Bayesian age-depth model for sediment core of Lake Chalco, Mexico (40-0 kcal BP) (NERC Grant NE/S009035/1)

A Bayesian age-depth model was constructed of the radiocarbon dates of the MexiDrill composite core. The age-depth model was produced using rbacon (Blaauw and Christen 2011, Bayesian Analysis 6(3): 457-474, doi: 10.1214/11-BA618), and was run in R as rbacon (CRAN version 3.2.0) using all default settings except for: thick=0.2, depth.units="m", ka=TRUE, acc.mean=2000. The output consists of a pdf of the age-depth model and its settings, a file containing the 95% age ranges, medians and means for every 0.1m of the core depths, a settings file and the .csv file that was used to produce the age-depth model. During the age-modelling, rbacon used the IntCal20 northern hemisphere terrestrial calibration curve (Reimer et al. 2020, Radiocarbon 62, 725-757, doi:10.1017/RDC.2020.41).
