  • Zeta potential measurements of rare earth element enriched apatite from Jacupiranga, Brazil under water and collector conditions. Zeta potential measurements can be used to indicate the surface behaviour of a mineral under different reagent conditions. Mineral surface behaviour is important in processing and extracting minerals from their host ore, which can be energy intensive. Apatite is a phosphate mineral which can become enriched with rare earth elements. Rare earth elements are important in a wide range of products from iPhones to wind turbines.

  • Geochemical analysis of pyroclasts from Aluto, Ethiopia. Data are referenced in Clarke et al., 2019: Fluidal pyroclasts reveal the intensity of peralkaline rhyolite pumice cone eruptions;

  • Tephra layer summary for Lake Abijata and Lake Langano cores, Ethiopia. Data are referenced in McNamara et al., 2018: Using Lake Sediment Cores to Improve Records of Volcanism at Aluto Volcano in the Main Ethiopian Rift;

  • Ascii files or tables with earthquake source and model parameters determined for the Wells, Nevada earthquake

  • Isotopic geochemical analysis of volcanic samples from across Ethiopia. Data are referenced in Hutchison et al., 2018: The evolution of magma during continental rifting: New constraints from the isotopic and trace element signatures of silicic magmas from Ethiopian volcanoes;

  • Ar/Ar dating of samples from Aluto and Corbetti volcanoes, Ethiopia. Data are referenced in Hutchison et al., 2016b: A pulse of mid-Pleistocene rift volcanism in Ethiopia at the dawn of modern humans;

  • The files contain backscattered (BSE) SEM images and photomicrographs of studied samples form Vanua Lava, Vanuatu (New Hebrides). The samples are mantle xenolith found in situ in lava boulders.

  • Groundwater level measurements collected by the state groundwater boards of Punjab and Haryana states, India, and by the Central Groundwater Board. The data consist of well locations and measurements of groundwater levels, in metres below the top of the well casing. Data were collected in both the pre-monsoon (May-June) and post-monsoon (October-November) periods. Data availability is irregular across the entire suite of wells.

  • The 5km Hex GS Running Sand dataset shows a generalised view of the GeoSure Running Sand v8 dataset to a hexagonal grid resolution of 64.95km coverage area (side length of 5km). This dataset indicates areas of potential ground movement in a helpful and user-friendly format. The rating is based on a highest level of susceptibility identified within that Hex area: Low (1), Moderate (2), Significant (3). Areas of localised significant rating are also indicated. The summarising process via spatial statistics at this scale may lead to under or over estimation of the extent of a hazard. The supporting GeoSure reports can help inform planning decisions and indicate causes of subsidence. The Running Sand methodology is based on the BGS Digital Map (DiGMapGB-50) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of the potential for a geological deposit to show running sand behaviour under the action of flowing water, a characteristic usually of saturated sand and silt grade material. Complete Great Britain national coverage is available.

  • Count data (original counts and percentage abundances) from nannofossil assemblage analysis of Early Miocene samples. These form the prime data for a paper submitted to Palaeogeography, Palaeoclimatology, Palaeoecology (Young et al. submitted, 2019).
