Rheometric data for suspensions of bubbles and/or particles in a Newtonian suspending liquid

Rheometric data for suspensions of bubbles and/or particles in a Newtonian suspending liquid. Experimental suspensions are intended as analogues for multiphase magma and lava (containing volatile bubbles and solid crystals). The dataset comprises data collected using a Anton Paar MCR702 rheometer. A Newtonian working fluid (sugar syrup) suspends variable fraction of gas bubbles and solid particles. Data relating to suspensions of bubbles only are found in the folder Bubble_Suspensions, and data relating to suspensions of bubbles and particles are found in the folder 3Phase_Suspensions. For all suspensions, rheometric data were collected in a wide-gap concentric cylinder geometry using both rotational rheometry (flow curves) and oscillatory rheometry (frequency sweeps). Bubble fraction and particle fraction are varied systematically. In each folder a matlab script is provided which facilitates extraction and analysis of the raw data, which are held in .csv files

Engineering Properties: Bulking

This dataset is a characterisation of the soil and rocks and the potential bulking factor (likely excavated volume increases) at Formation (local to regional) level for Great Britain. The data is categorised into Class, characteristics of similar soils and rocks and Bulking Factor, range or ranges of % bulking. The excavation of rocks or soils is usually accompanied by a change in volume. This change in volume is referred to as ‘bulking’ and the measure of the change is the ‘bulking factor’. The bulking factor is used to estimate the likely excavated volumes that will need to be moved, stored on site, or removed from site. It is envisaged that the 'Engineering Properties: Bulking of soils and rocks' dataset will be of use to companies involved in the estimation of the volume of excavated material for civil engineering operations. These operations may include, but are not limited to, resource estimation, transportation, storage, disposal and the use of excavated materials as engineered fill. It forms part of the DiGMap Plus dataset series of GIS layers which describe the engineering properties of materials from the base of pedological soil down to c. 3m depth (ie the uppermost c.2m of geology). These deposits display a variable degree of weathering, but still exhibit core engineering characteristics relating to their lithologies.

Data on gas composition in headspace of borehole NB04. Contains 11 columns of data taken from the headspace of borehole NB04 (at the clay-dominated site) using a GasClam 2.0 (Salamander Group, UK) that continuously measure temperature, atmospheric pressure, borehole pressure, and the percentage of carbon dioxide, oxygen, and methane in the borehole. All data collection for the GOAM project was performed on the same sites located in the Kien Svay district of northern Kandal Province, Cambodia, southeast of Phnom Penh. These sites are referred to as "clay-dominated" and "sand-dominated" in reference to the known lithology and are known for high arsenic concentrations (Richards et al., 2017). Each site contained four 18 m boreholes installed in January 2019 using manual drilling described in Richards et al (2015), spaced evenly about ~1.5 m apart. The boreholes that were located at the clay-dominated site are referred to NB01, NB02, NB03 and NB04. The boreholes that were located at the sand-dominated site are referred to as NB05, NB06, NB07 and NB08. The data taken are from the headspace of borehole NB04 (at the clay-dominated site) This file contains part of the data produced for NERC grant NE/P01304X/1 - called Genetic and molecular basis of organic-arsenic-microbe interactions in arsenic prone aquifers ("GOAM") project.

Geochemical results from upper Ediacaran organic-rich shales / mudstones, Yangtze Craton, South China

These data comprise geochemical results from upper Ediacaran organic-rich shales / mudstones from the Yangtze Craton (South China) from the Doushantuo Formation (member IV) and overlying lower Dengying Formation (= Miaohe Member). Ages range from about 570 to 550 Ma. The data consist of iron partitioning (Fe-speciation), phosphorus partitioning (P-speciation), bulk rock metal concentrations, total organic content and pyrite sulfur isotopes. Major and trace element concentrations of all samples were measured by inductively coupled plasma optical emission spectrometry and mass spectrometry, respectively, after quantitative HNO3-HFHClO4 digestion. Fe speciation was performed after the established methodology of Poulton and Canfield to extract operationally defined Fe phases, including Fe associated with carbonates (Fecarb), ferric oxides (Feox), magnetite (Femag), and pyrite (Fepy). The sum of these Fe pools constitutes the proportion of Fe that is considered highly reactive (FeHR) toward dissolved sulfide. Ratios of FeHR/FeT > 0.38 support FeHR enrichment and deposition under anoxic bottom water conditions, whereas values of <0.22 indicate deposition from oxic bottom waters. The intermediate range of 0.22 to 0.38 is regarded as equivocal because of the possibility for rapid sediment deposition or early diagenetic transformation of unsulfidized FeHR to poorly reactive sheet silicate minerals. For anoxic samples (FeHR/FeT > 0.38), the degree of sulfidation of the FeHR pool can be used to distinguish ferruginous (Fepy/FeHR <0.7) from euxinic (Fepy/FeHR > 0.8) conditions, with an intermediate zone ascribed to “possible euxinia”. Recent analyses of Holocene sapropels and the euxinic Lake Cadagno indicate that Fepy/FeHR > 0.6 may be a more suitable threshold for distinguishing ferruginous from possible euxinic conditions. Selected shale samples were analyzed for pyrite sulfur isotopes (δ34Spy), TOC, organic carbon isotopes (δ13Corg), and P phase associations. The P measurements use a sequential extraction method to distinguish the proportion of total P (PTot) associated with detrital apatite (Pdet) relative to potentially bioavailable and reactive (Preac) minerals, including Fe (oxyhydr)oxides (PFe),organic matter (Porg), and authigenic carbonate fluorapatite, biogenic apatite, and CaCO3-bound P (Pauth).

EU Project: CO2STORE (On-land long term saline aquifer CO2-storage)

EU is required to reduce its CO2 emissions by 8% by 2008-2012, later deeper cuts are foreseen. CO2 underground storage is one of the few options that can meet these obligations. The present project investigates four new potential cases for CO2-reservoirs, mainly on land. It will continue reservoir simulations and study geochemical reactions to develop final-fate prediction models. This will be supported by new seismic observations. At the same time gravimetrics is introduced as a new method better suited on land. This proposal builds directly on the Thermie/5FP SACS2 project results, which involved monitoring and modelling the injection of CO2 into the Utsira Sand aquifer, at Sleipner gas field, offshore Norway.

GeoSure Insurance Product V7 2015.3

The GeoSure Insurance Product (GIP) dataset identifies potential natural ground movement hazard within Great Britain by postcode. These data are available in GIS point feature and database format, updated on a 6 monthly basis. The GeoSure Insurance Product represents the end of an interpretation process starting with the BGS Digital Geological Map of Great Britain at the 1:50,000 scale (DiGMapGB-50). This digital map is the definitive record of the types of rocks underlying Great Britain (excluding Northern Ireland), as represented by various layers, starting with Bedrock and moving up to overlying Superficial layers. In 2003, the BGS published a series of GIS digital maps identifying areas of potential natural ground movement hazard in Great Britain, called GeoSure, demonstrating a grade of potential for 6 separate hazards: shrink-swell clays, slope instability, dissolution of soluble ground, running sand, compressible and collapsible deposits. These maps were derived by combining the rock-type information from DiGMapGB-50 with a series of other influencing factors which may cause the geological hazards (e.g. steep slopes, groundwater). In 2005, the BGS used the GeoSure maps to make an interpretation of subsidence insurance risk for the British property insurance industry, released as the GeoSure Insurance Product. This represents the combined effects of the 6 GeoSure hazards on buildings in a postcode database. The combined hazard is represented numerically in the database as the Total Hazard Score, with a breakdown into the component hazards. The methodology behind these data involves balancing the 6 GeoSure natural ground stability hazards against each other. The GeoSure maps themselves have a fivefold coding (A to E), and the balancing exercise involves comparing each level across the six hazards e.g. comparing a level C shrink-swell clay area with a level C running sand area. Each level of each of the hazards is given a 'hazard score' which can then be added together to derive a Total Hazard Score within a 300m radius from the population weighted postcode point.
