    Results of piston cylinder experiments on lower-crustal material from the Ivrea Zone, Italian Alps. Natural sulfides and sulfide-silicate mixes from lower crustal cumulates were heated and pressurised to conditions matching those of the MASH zone, which is hypothesised to be the source of metals for post-collisional porphyry Cu deposits. This was done in order to simulate partial melting and examine the mobility of metals in this environment. This data contains experimental logs stating the experimental conditions; reflected light photographs of the experimental capsules; scanning electron microscope element maps and identification of platinum group minerals and precious metal minerals in the capsules; and trace element concentration of sulfides in the capsules. This data was collected as part of the TeaSe consortium NERC grant in order to test hypotheses about porphyry Cu deposit formation. This data was collected by researchers at Cardiff University and the University of Edinburgh.

    Mineralogical and geochemical data from sulphides and other ore minerals from the Skouries porphyry Cu-Au deposit, Greece. Samples were taken from several boreholes from the Skouries mine, courtesy of Eldorado Gold Corporation. This data contains petrological photographs; identification of platinum group minerals and precious metal minerals; and trace element concentration of ore minerals. This data was collected as part of the TeaSe consortium NERC grant in order to determine the concentration and hosting of critical and precious metals in various types of ore deposits and barren rocks from different geological environments. This data was collected and interpreted by researchers at Cardiff University and is used in a paper, available at https://doi.org/10.1016/j.oregeorev.2018.06.014.

    The project is aimed at understanding how a number of economically and geologically important chemical elements partition themselves between the silicates of the outer parts of the Earth and sulphides, minerals and liquids rich in sulphur. Although sulphur is not very abundant in the Earth, it has a powerful impact on the behaviour of a wide range of elements in Earth's crust and underlying mantle. For example, the majority of ore bodies rich in nickel, copper, gold and platinum are sulphides. Many of them are formed when sulphides separate from molten silicates in volcanic areas. A principal aim of my project is to experimentally reproduce the conditions under which sulphides separate and to determine how they extract the economically important elements from the host volcanic rocks. A second aim is to use my experimental results to determine whether or not a large mass of sulphide was extracted from the molten earth early in its history (4500 million years ago) and dissolved into the metallic core. In order to study how elements are distributed into sulphide I perform experiments at high pressures and temperatures, typically 15000 atmospheres pressure and 1400 degrees C in a large hydraulic press. After treatment at high pressure and temperature, the samples (typically about 1x1x1 millimeters) are rapidly cooled to room temperature and pressure and examined using a range of microanalytical techniques. The latter enables me to resolve chemical composition on the scale of 10 microns (or 10 millionth's of a meter).

    Pictures of sulphides and trace element concentrations from ore minerals in the El Teniente porphyry Cu-Mo deposit, Chile. Samples were picked for analysis from the Natural History Museum London’s ore collection. This data contains petrological photographs and trace element concentration of ore minerals. This data was collected as part of the TeaSe consortium NERC grant in order to determine the concentration and hosting of critical and precious metals in various types of ore deposits and barren rocks from different geological environments. This data was collected and interpreted by researchers at Cardiff University.

    The dataset is a Soil Corrosivity Map for the U.K. based on the BGS DIGMapGB-PLUS Map. The creation of this dataset involves scoring the Soil Parent Material types for five different attributes that contribute towards the corrosion of underground assets. These are (i) high or low soil pH, (ii) general soil moisture, (iii) the likelihood that soil saturated and undergo periods of anaerobic conditions, (iv) the presence of sulphides and sulphates and (v) the resistivity of the soil parent material. The scoring of each of these parameters was undertaken based on the Cast Iron Pipe Association (CIPA) (now the Ductile Iron Pipe Research Association, DIPRA) rating system. By combining the scores of each parameter a GIS layer has been created that identifies those areas that may provide a corrosive environment to underground cast iron assets. The final map has been classified into three categories signifying: 'GROUND CONDITIONS BENEATH TOPSOIL ARE UNLIKELY TO CAUSE CORROSION OF IRON', 'GROUND CONDITIONS BENEATH TOPSOIL MAY CAUSE CORROSION TO IRON', 'GROUND CONDITIONS BENEATH TOPSOIL ARE LIKELY TO CAUSE CORROSION TO IRON'. The dataset is designed to aid engineers and planners in the management of and maintenance of underground ferrous assets.
