U-Pb isotope ratio data set for numerous phosphate (apatite) grains in two thin section samples of the LL5 S4-6 Chelyabinsk meteorite. One section is of the S4-6 light lithology, and another of the S5-6 dark lithology. Samples analysed were section ‘A' (light lithology) and section ‘B’ (dark lithology) of Chelyabinsk, both from the Open University School of Physical Sciences sample collection. The results demonstrate variability in degree of Pb-loss during collisional reheating from pristine versus damaged apatite crystal domains. These results are reported for a meteorite fall which originally happened near Chelyabinsk in Russia. The results otherwise have no geographic location, as this is a sample of an asteroid. All measurements were made in December 2020. These data were collected using Secondary Ionisation Mass Spectrometry (SIMS) with a CAMECA IMS 1280 at the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS). The thin sections were polished with colloidal silica, cleaned, and coated with gold prior to analysis. Microtextural information was obtained prior to analysis using a combination of back-scatter-electron, cathodoluminescence, and electron-back-scatter-diffraction analysis. Data were obtained to test hypotheses relating to the competition between macro-to-meso-scale thermally-driven variation in Pb-loss rates versus microscale variation driven by grain-specific features, e.g., fracture networks. An article describing and discussing these results, including further methodological steps in their collection and processing, is due for publication.

Numerical models of mass flows and tsunamis that they generated with their entrance in the sea. The mass flows propagate in the Sciara del Fuoco of Stromboli. The mass flows are not real events, but are rather used as a sensitivity analysis to examine tsunamigenic potential of mass flows of landslides and pyroclastic flows of different durations, volumes and coherence. The data was generated with the two fluid version of the Volcflow model. The material includes tsunami height measurements (plotted as well as raw data) for each run recorded by virtual gauges located around the island (map of gauges included), maximum wave height data in the area around the island and at the shores, a video visualisation of the mass flows and resultant tsunami waves, and a figure of the final deposit from each modelled mass flow. The numerical model simulations were carried out by Symeon Makris. The Volcflow code is not included in the submitted material but it is open source and can be downloaded here: https://lmv.uca.fr/volcflow/

All paleointensity data gathered from the project at University of Liverpool. The data is divided into multiple four letter coded sections which refer to a specific locality and/or experiment type. The sections are as follows: CFEH - Thermal paleointensity experiment on natural clinkers from Montana, USA, looking primarily at the Epsilon Hematite phase, with an additional high-power alternating field demagnetisation step after each infield step of the experiment. LPRM - volcanic material from Kinghorn and Wormit Bay, Scotland (335 and 410 million years old). This was a specific experiment with samples given a prior high temperature applied field of 80 micro Tesla and a pressure remanent magnetisation of 80 micro Tesla. VFSS – a microwave paleointensity experiment carried out on Scottish vitrified fort material, sampled in the 1980s. WTBY – microwave paleointensity experiments carried out on Scottish volcanics from Wormit Bay. Sampled September 2015. YDSR – volcanics from Yandiniling Dike Swarm, in Yilgarn Craton, Australia, 2.6 billion years old. Sampled Nov 2018. Sampled with Yebo Li from the University of Curtin (Perth) as part of a collaboration, resampling of 16WDS sites from his palaeodirections paper. These were microwave demagnetisation (specimen orientation only) and paleointensities. NERC grant NE/P00170X/1.

Nanoscopic (50 < size < 150 nm) magnetic particles embedded within the unaltered interior of mineral crystals like zircons (ZrSiO 4 ) make ideal candidates to record the information about the earth's magnetic field (geodynamo). Information regarding the magnitude of the field can be obtained by measuring the natural remnant magnetization (NRM) of these carriers and further information on the approximate size range of the carriers can be obtained by carrying out thermal remnant magnetization measurements (TRM). However very little is known about the actual morphology and spatial distribution of these carriers in order to understand the fundamental parameters influencing paleomagnetic recording. We propose to image pristine zircons crystals with simple geological histories containing large remnant magnetization using ptychotomography in order to investigate the size, shape and spatial distribution of nano-paleomagnetic carriers. This would also give us an opportunity to fine tune the ptychotomographic setup at I13-coherence branch. This data package consists of 3D maps of Bishop Tuff Zircons, relatively young. The folders contain a stack of .tiff files which can be loaded into imagej, dragonfly, aviso for segmentation purposes.

A core scanning dataset from part of the Llanbedr (Mochras Farm) drill core that was drilled onshore in the Cardigan Bay Basin, Wales, UK. This core scan dataset was obtained using the Itrax XRF Scanner MC at the Core Scanning Facility (CSF) at the British Geological Survey (BGS), UK. It contains X-ray fluorescence (XRF) elemental data expressed as elemental counts or peak areas and optical images of each representative core stick. The dataset was created within the scope of the JET project (Integrated understanding of Early Jurassic Earth system and timescale) - https://gtr.ukri.org/projects?ref=NE%2FN018508%2F1 This project has received funding from the International Continental Scientific Drilling Programme (ICDP) and the UK Natural Environment Research Council (NERC).

The UK Geoenergy Observatories (UKGEOS) Glasgow 3D coal mine model outputs, created by the British Geological Survey, provide a semi-regional overview of the depth and extent of surveyed and probable coal mine workings, plus stone and coal roads surveyed within the mines. The model allows users to visualise the surveyed and probable coal mine workings to be found beneath this part of Glasgow, applicable at a scale of around 1: 25,000 to 1: 10,000. The data is supplied as grids, triangulated surfaces over a 5 by 4.15 km area, with the depth range to around 300 m below Ordnance Datum. The mine extents are ‘cut out’ of the UKGEOS Glasgow post-drill bedrock model. This model describes both surveyed (recorded on mine abandonment plan) and probable coal mine workings. An area of probable workings has been updated to account for the results of drilling borehole GGC01. Further details and model limitations can be found in the accompanying metadata report http://nora.nerc.ac.uk/id/eprint/531157/

The BGS Permeability Index dataset shows estimated rates of water movement from the ground surface to the water table. The v8 dataset incorporates the latest geology mapping (BGS Geology 50k). This includes updates to the lithology-coding schema, the LEX_RCS. A 2-part code used to identify the named rock unit from the BGS lexicon of named rock units (LEX) followed by a Rock Classification Scheme (RCS) code which describes the rocks lithological characteristics e.g. texture and composition. Updates to these codes and latest dissolution hazard data sourced from BGS GeoSure: Soluble Rocks have been reviewed and classified as part of the version 8 release. The dataset covers Great Britain and is presented at a scale of 1:50 000, based on the geological data at the same scale. However, in areas where the geology is not mapped to this scale, the next best available scale is used. The BGS Permeability Index can be used to compare the relative permeability of deposits at the regional scale, indicating where highly permeable rocks could allow rapid infiltration to occur, or where less permeable rocks are present and water could pond on the ground surface. The dataset can be used as a component in a wide range of geo-environmental assessments such as natural flood management, Sustainable Drainage Systems, engineering desk studies, slope stability, and aquifer vulnerability. It is for use at the regional scale and is not recommended for use at the site-specific scale.

Compositional and volcanological data from a small-volume explosive-effusive volcanic eruption on Ascension Island, South Atlantic. Multiple samples of pumice and lava spanning the whole eruption sequence were collected from several locations in the area surrounding NE-Bay on Ascension Island. This dataset includes compositional, clast size, abundance, clast density and vesicle texture data for the products of the Echo Canyon eruption. Data was collected between the 12th June 2018 and the 30th August 2020 on Ascension Island and at the University of East Anglia, UK. Compositional data was collected using X-ray fluorescence (XRF), density of pumice clasts using the Archimedes suspension method and textural data by visual inspection of sample vesicle shape and size, all at the University of East Anglia, UK. Clast size and abundance was semi-quantitatively estimated in the field on Ascension Island and later checked against photographs. This data provides a framework through which changes to eruption style were reconstructed and is useful to any persons wishing to study or compare small-volume eruption deposits which record eruptive transitions. The data supports and forms the basis of Davies et al., (2021) (DOI : 10.1007/s00445-021-01480-1) and forms part of B V Davies’ Natural Environment Research Council funded PhD project investigating eruption controls on Ascension Island. Bridie V Davies collected and interpreted the data with assistance from Jane H Scarrow and Richard J Brown on Ascension Island, and Jenni Barclay at the University of East Anglia, Bertrand Leze performed XRF on prepared samples. All data collected is included in this resource.

The dataset consists of a series of input and output files for the 1D and 3D numerical models used to demonstrate the impact of heat mining for a 100-m long vertical Borehole Heat Exchanger (BHE) in Scotland, assuming a constant or fluctuating surface heat flux. Simulations for a constant heat extraction from the BHE were performed using an updated version of the open-source OpenGeoSys finite-element modelling software (https://www.opengeosys.org/) made available in this repository. This updated version allows for calculation of the energy change in each material group in the models, as part of the HEAT_TRANSPORT process. For each model, the input files include the mesh file (MSH), the Boundary conditions (BC), geometry (GLI), Initial conditions (IC), Fluid properties (MFP), Medium properties (MMP), Material solid properties (MSP), Numerical parameters (NUM), Ouput parameters (OUT), Process (PCS), Reference (RFD), Source-term (ST) and Time (TIM) files. The output files consists of temperature time-series, 1D and 2D temperature profiles extracted from the models domain at different time steps (i.e. Tecplot output files) and of a text file indicating the energy content of each material group at each time step.
