Geochemistry and geochronology data relating to the II-RHY-1 tephra horizon, the Thórsmörk Ignimbrite, and Torfajökull and Tindfjallajökull volcanoes, Iceland.

Jonathan Moles, The Open University

2019

The data are associated with a paper entitled ‘Widespread tephra dispersal and ignimbrite emplacement from a subglacial volcano (Torfajökull, Iceland)’ by J Moles et al. (2019). See paper for full details. Data types: major element geochemistry; trace element geochemistry; 40Ar/39Ar...

X-ray Microtomography of Intermittency in Multiphase Flow at Steady State Using a Differential Imaging Method

Martin Blunt, Imperial College London | Ying Gao, Imperial College London | Qatar Carbonates And Carbon Storage Research Centre

2018

The images in this dataset are a sample of Bentheimer Sandstone from a micro-computed tomography (micro-CT) scan acquired with a voxel resolution of 6.00µm. We imaged the steady state flow of brine and decane in Bentheimer sandstone. We devised an experimental method based on differential...

Three-dimensional temporal imaging of X-ray CT imaging of dissolution-driven convection in glass beads

Dr Ronny Pini, Imperial College London | Rebecca Liyanage, Imperial College London | Qatar Carbonates And Carbon Storage Research Centre

2018

The images in this dataset show the mixing of two liquid solutions in a random bead pack as a function of time and in three-dimensions. The working fluids used in this study are solutions of methanol and ethylene-glycol (MEG, fluid 1) and brine (fluid 2). In particular, three mixtures of...

Relative Permeability and Flow Intermittency Measurements Using X-Ray Micro-tomography in a Complex Microporous Carbonate

Ying Gao, Imperial College London | Ali Q. Raeini, Imperial College London | Martin J. Blunt, Imperial College London | Branko Bijeljic, Imperial College London

2019

We imaged the steady-state flow of brine and decane at different fractional flows during dual injection in a micro-porous limestone using X-ray micro-tomography. We applied differential imaging on Estaillades carbonate to (a) distinguish micro-porous regions from macro-pores, and (b)...

Pore-Scale Dissolution by CO2 Saturated Brine in a Multi-Mineral Carbonate at Reservoir Conditions: Impact of Physical and Chemical Heterogeneity

Al-Khulaifi, Y.; Imperial College London | Lin, Q.; Imperial College London | Blunt, M.J.; Imperial College London | Bijeljic, B.; Imperial College London

2019

The datasets contain 40 time-resolved segmented X-ray micro-tomographic images showing mineral dissolution of carbonate rock samples containing dolomite and calcite via CO2 acidified brine fluid flow at reservoir conditions. The tomographic images were acquired at a voxel-resolution of 5.2 µm...

Nama Group geochemistry

Rosalie Tostevin, University College London

2019

Rare earth element, major and minor element, and iron speciation data for nine independent sections in the Nama Group, described in detail in Wood et al., 2015, Precambrian Research, and Tostevin et al., 2016, Nature Communications. Additional data for Zebra River section include sulfur...

Silica rheology data

Simon Hunt, University College London

2018

Synchrotron X-radiography (images) and diffraction data collected to measure rheology of Quartz coesite and stishovite.

Walker-Verkuil, K | Bearcock, J M | Mulcahy, A | Palumbo-Roe, B | MacAllister, DJ | Gooddy, D C | Darling, W G

2022

The data release includes surface and groundwater chemistry data from 86 samples (20 surface water, 60 ground water, and 6 ground water duplicates) collected during the baseline water monitoring at the UK Geoenergy Observatories (UKGEOS) Glasgow facility. This release from the British...

UK Geoenergy Observatories (UKGEOS) Glasgow pre-drill coal mine model

British Geological Survey

2019

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...
