Identification

Title

Scanning Electron Microscope (SEM) data from samples collected from sites of lithified artifical ground (Warton, Glengarnock, Derwent Howe, Harrington, Auchendinny, Lynemouth) in Scotland and northwest England (2022-2023) (NERC Grant NE/X009718/1)

Abstract

This dataset contains SEM data comprising raw data files (.dat) and AZtec file (.oip) for reading the data. The data was collected in 2022-2023. The data was collected for the purpose of visualising spatial textures and microstructures in the collected samples. The data was collected by John MacDonald, Connor Brolly and Robin Hilderman (University of Glasgow) who retain the original data.

Lineage

Sample imaging and chemical mapping was conducted on polished thin sections with a ca 20 nm carbon coating using a Zeiss Sigma variable pressure field-emission-gun scanning electron microscope (VP-FEGSEM) equipped with an Oxford Instruments Ultimax 170 mm2 Silicon Drift Detector Energy dispersive detector, based in the geoanalytical electron microscopy and spectroscopy (GEMS) facility at the University of Glasgow. Backscattered electron (BSE) imaging and energy-dispersive X-ray spectroscopy (EDX) were conducted in high vacuum using high current mode and accelerating voltage of 20 kV, working distance of 8.0 mm and aperture of 60 μm. The EDX mapping data were acquired and processed using the Oxford Instrument AZtec software. All EDX maps shown have had the AZtec true map function applied, that removes background and artefacts, and resolves issues with element peak overlaps. The raw data files (.dat files) must not be moved in terms of their location relative to the AZtec file (.oip file). The .dat files cannot themselves be opened, but opening the .oip file (using AZtec software from Oxford Instruments) reads the .dat files.
