Model metadata report for the post-drill superficial deposits model, UK Geoenergy Observatory in Glasgow

This report presents the metadata behind the post-drill superficial deposits 3D geological model data release, developed by the British Geological Survey (BGS), for the UK Geoenergy Observatory in Glasgow (UKGEOS). The site is located within the Clyde Gateway regeneration area of eastern Glasgow (Glasgow City Council) and Rutherglen (South Lanarkshire Council), central Scotland, UK. The superficial deposits in the Clyde valley consist of a complex succession of glacial till, marine, lacustrine and fluvio-glacial deposits, overlain by fluvial deposits, recent alluvium and anthropogenic deposits, which locally reach around 50 m in thickness. There is widespread made, filled and landscaped ground mantling the natural superficial deposits. The geological information in this report and accompanying 3D model characterise the various superficial deposits, and give an indication of their thickness and lateral extent. This has created a better understanding of the Quaternary (superficial) geology of the Glasgow Observatory area. The model allows users to visualise the subsurface sequences to be found beneath the Glasgow Observatory site and the surrounding area. The model presented in this report builds on previous superficial deposit models of the Glasgow area, developed by BGS since 2005. A number of reports have been published describing previous models of the area, including Merritt et al. (2009), Monaghan et al. (2012, 2014) and Arkley et al. (2013). The pre-drill Glasgow Observatory model (Arkley, 2019) incorporated additional borehole data to increase the model resolution in the vicinity of the Glasgow Observatory borehole sites and incorporated post-2005 to pre-2018 borehole data received by BGS. This version of the model has been updated in the vicinity of the Glasgow Observatory boreholes and represents a UKGEOS ‘post-drill’ understanding of the superficial deposits in and around the Glasgow Observatory. The models are an interpretation of digital datasets held by the British Geological Survey. A summary of the construction method, limitations of the models and a brief description of the modelled units are given
