BGS Geology 10k - 25k (DiGMapGB-10 & DiGMapGB-25) Artificial version 3

Data identifies landscape areas (shown as polygons) attributed with type of artificial or man-made ground. It indicates areas where the ground surface has been significantly modified by human activity. The scale of the data is 1:10 000 and 1:25 000 scale. Onshore coverage is partial with approximately 52% of England, Scotland, and Wales available in the version 3 data release. BGS intend to continue developing coverage at this scale; current focus is to include all large priority urban areas, along with road and rail transport corridors. Types of artificial ground include: Disturbed ground areas of ill-defined shallow or near surface mineral workings where distinction cannot be made between made and worked ground. Infilled ground areas where original geology has been removed and then wholly or partially back filled includes waste or landfill sites. Landscaped ground areas where surface has been reshaped includes former sand and gravel workings for recreation and amenity use. Made ground man made features including embankments and spoil heaps. Reclaimed ground are areas of land fill, where new ground is created, usually in coastal margins, may be for example a consequence of draining of submerged wetlands and beach rebuilding. Worked ground areas where ground has been removed including quarries and road cuttings. Whilst artificial ground may not be considered as part of the 'real geology' of bedrock and superficial deposits it does affect them. Artificial ground impacts on the near surface ground conditions which are important to human activities and economic development. Due to the constantly changing nature of land use and re-use/redevelopment caution must be exercised when using this data as it represents a snapshot in time rather than an evolving picture hence the data may become dated very rapidly. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles and are available under BGS data licence.

Nitrogen fixation rates and isotopic measurements of aqueous nitrite and nitrate from spark discharge experiments (NERC Grant NE/V010824/1)

Concentrations of gaseous and aqueous fixed nitrogen products and isotopic measurements of aqueous nitrite and nitrate in spark discharge experiments. Spark experiments were conducted at the University of St Andrews in the St Andrews Isotope Geochemistry Lab (StAIG) between November 2020 and February 2022. Analysis of gaseous products was carried out with a quadrupole mass spectrometer (Hiden Analytical ExQ Quantitative Gas Analyser) in St Andrews. Measurement of concentrations of aqueous nitrite and nitrate and their isotopic composition were carried out for one part of the samples in St Andrews and for the other part at Brown University, Rhode Island, USA. The data was collected to investigate the efficiency of nitrogen fixation by lightning in different gas compositions, resembling the atmospheres of modern and early Earth. The isotope data was used to determine the role of lightning in the delivery of nutrients to the earliest ecosystems on Earth by comparing our results to measurements of sedimentary rock samples from the Archean. The experimental set up was built by Patrick Barth and Eva E. Stüeken, the experiments were conducted by Patrick Barth, Lukas Rossmanith, and Yuqian Peng, the analysis conducted by Patrick Barth, Lukas Rossmanith, Yuqian Peng, and Wendell Walters with support from Mark Claire, and the data was analysed by Patrick Barth, Eva E. Stüeken, Christiane Helling, and Wendell Walters. This dataset includes all data that is reliable and was used in the accompanying publication.

Ocean island olivine and spinel major element compositions (NERC Grant NE/T012455/1)

The dataset consists of elemental compositions determined for olivine and spinel from 13 ocean islands, including Azores, Balleny, Cook-Austral, Crozet, Cape Verde, Fernando de Noronha, Galapagos, Juan Fernandez, Marquesas, Society, Tristan-Gough, Tahiti, and Trindade). These samples were loaned from Sedgwick Museum, University of Cambridge and National History Museum, London, except the Galapagos samples provided by D. Geist. Elemental compositions determined for three secondary standards (San Carlos olivine, MongOl olivine, and NHNM164905 augite) are also included in the dataset. The data were acquired using a Cameca SX100 electron microscope at the Department of Earth Sciences, University of Cambridge, in June, July, August and November 2021. The elements analysed include Mg, Si, Fe, Al, Ca, P, Cr, Mn, and Ni in olivine, and Mg, Si, Fe, Al, Ca, Cr, Mn, and Ti in spinel. Data acquired from each analysis were saved in four txt files, which are for oxide concentrations, elemental concentrations, standard deviation, and detection limit, respectively. The data for ocean island samples were used to calculate olivine crystallisation temperature and mantle potential temperature based on an aluminium-in-olivine thermometer and modelling of mantle melting. All data collected within the project duration are in this dataset.

BGS Seabed Geology 10k: Offshore Yorkshire version 1.0

The BGS Seabed Geology 10k: Offshore Yorkshire digital map provides detailed and accurate characterisation of the seabed geology, based on seabed and shallow-subsurface data. This dataset incorporates three complementary map components (Substrate Geology, Structural Geology, and Geomorphology) presented at 1:10 000 scale, provided as discrete layers for viewing within a Geographic Information System (GIS). The bedrock geology comprises Triassic, Jurassic, and Cretaceous sedimentary rocks, with bedrock commonly outcropping in the northern and central parts of the map area. Triassic rocks of the Bacton, Haisborough, and Lias Groups are dominant in the north, whereas Cretaceous Chalk is dominant in the central areas. Extensive folding, fracturing, and faulting are observed at rockhead, indicative of the complex structural evolution of the Southern North Sea Basin. Superficial deposits comprise several Quaternary deposits, in particular, Late Pleistocene subglacial till of the Bolders Bank Formation. Post-glacial channel-infill deposits are also common as well as Holocene through modern unconsolidated marine sediments. The seabed geomorphology records a range of relict and active processes, including bedrock ‘Bedding ridges’, Late Pleistocene ‘Ice-marginal moraines’, and active marine sedimentary current-induced bedforms (e.g. ‘Sediment Waves’). Each theme is provided as distinct layers for viewing within a Geographic Information System (GIS). The “Substrate Geology” layer shows the distribution of bedrock and unlithified superficial deposits present at the seabed (below a thin veneer of seabed sediments, ‘one-metre principle’ described below) as a series of polygons; The “Structural Geology” layer represents the structural features observed at rockhead as a polylines layer, and “Geomorphology” theme consists of points, polylines, and polygons layers to portray the main seabed morphological and geomorphological features.

Indicative Atlas of Radon Potential for Great Britain version 3

Radon is a natural radioactive gas which enters buildings from the ground. The joint UK Health Security Agency (UKHSA) - British Geological Survey (BGS) Digital Indicative Atlas of Radon in Great Britain presents an overview of the results of detailed mapping of radon potential, defined as the estimated percentage of homes in an area above the Radon Action Level. Exposure to high concentrations increases the risk of lung cancer. UKHSA (formerly Public Health England) recommends that radon levels should be reduced in homes where the annual average is at or above 200 becquerels per cubic metre (200 Bq m-3). This is termed the Action Level. The UK Health Security Agency defines radon affected areas as those with 1% chance or more of a house having a radon concentration at or above the action level of 200 Bq m-3. The Indicative Atlas of Radon in Great Britain presents a simplified version of the radon potential for Great Britain, in which each 1 km grid square is classed according to the highest radon potential found within it, so the dataset is indicative rather than definitive. The joint UKHSA-BGS Digital Radon Potential for Great Britain dataset provides the current definitive map of Radon Affected Areas in Great Britain.

The effect of clay content on the dilatancy and frictional properties of fault gouge (NERC Grant NE/L002469/1)

This information details the method of calculating dilatancy from pore volumometry measurements. In the velocity step tests, an initial shear enhanced compaction phase drastically reduces the sample pore volume until the sample yields. After the sample yields, the pore volume continues to decrease but at a lower rate of decrease. The imposed velocity steps cause compaction or dilation of the sample material that is superimposed on this overall compaction trend. Pore pressure is held at a set point in all tests and any volume changes in the control system are assumed to correspond directly to changes in pore volume in the sample. The method here is aimed at producing quantitative, reproducible values for dilatancy from experimental data. The script fits a polynomial function to all the volume data to give the overall trend of the shear enhanced compaction. The data position of the start of the velocity step of interest is entered manually into the function. When dilatancy occurs on a step change in velocity, this is not immediately recorded using volumometry, as the permeability of the sample will produce a transient response as pore fluid pressure equilibrates between the sample and the pore fluid pressure system. To discount time effects, every velocity step was processed with a ‘time_dep’ phase for the first 100µm of displacement after the imposed velocity step change. Using the values for ‘vel_step’ and ‘time_dep’, the volumometry data are split into separate matrices incorporating time and volume preceding and following the velocity step change. A linear regression model fits a polynomial curve to the pore volumometry data and returns the coefficient of determination (R2) for the fit of the model. The shear enhanced compaction phase prior to yield is included in the fit. The code incrementally adds the value entered for ‘step’ to the data in the velocity step of interest. This ‘step’ value is a positive or negative value depending on whether the velocity has increased or decreased, respectively. A new linear regression model is then fitted to the whole dataset and if the R2 value has increased, the code will continue to loop to add the value of ‘step’ to the pore volume data. It concludes when the R2 value reaches a peak and begins to decrease, as the fit is no longer improving. We assume at this point that the effect of the dilatancy due to the velocity step has been removed, and the cumulative sum of the ‘step’ values is equivalent to the dilatancy. As the loop goes one iteration past the optimum R2 value, the code reverts to the previous set of values with the best R2 value. In experiments with multiple velocity step changes, the code needs to retain the previous corrections of the data. The function ‘pf_correct’ is used to correct the velocity steps that have been previously processed. The values for ‘vel_step’, ‘time_dep’ and the returned value of ‘offset’ need to be given in the inputs for ‘pf_correct’.

Archived geochemical, geospatial, and geochronological data associated with individual rock units contained within stratigraphic columns (covering North America and New Zealand) in the Macrostrat.org database (NERC Grant NE/L002507/1)

Macrostrat.org is a live database project collecting geochemical, geospatial, and geochronological data associated with specific rock units within stratigraphic columns with a geographic footprint. The data in Macrostrat is an aggregate of previously reported measurements in the literature. The database is constantly updated, expanded, and improved. Hence, data are archived (5-2-23) in this file for posterity in support of the manuscript titled "Evolution of the crustal phosphorus reservoir" (Walton et al., 2023). In all measurements in the data file: ages are in millions of years (Ma) and elemental compositions are in wt%. Further details of all definitions and standards in Macrostrat data reporting are permanently available at https://macrostrat.org/api/defs. Macrostrat data are useful for weighting geochemical data by the relative areal and volume abundance of the rock units from which they derive, helping to address questions of (over/under) sampling-induced bias. Data in these files represent direct exports from Macrostrat.org via the API root, supplemented with data from Reinhard et al (2017). Unit areal extents for data from Reinhard et al 2017) are approximated with the relevant Eon average from Macrostrat.org. Macrostrat.org is maintained by Shanan Dr Peters, Dr Daven Quinn, and the hard work of many others (https://macrostrat.org/#people).
