User guide for the BGS UK Coal Resource for New Exploitation Technologies (Version 1) dataset

This report describes the Coal for New Technologies GIS dataset, which is a suite of data layers developed in 2004 by the British Geological Survey (BGS), with the assistance of Wardell Armstrong and Imperial College, London. The principle aim of the original study was to develop a methodology to assess the potential of the UK onshore coal resources for both exploitation by conventional (mining) and new technologies. Digital data was created using a Geographic Information System (GIS) to produce the delivered output of the original project, a series of paper maps that would identify prospective areas. The Coal for New Technologies digital data has been derived from the original source data. No updating has been carried out and has been published in its original format under Open Government Licence as a set of data layers covering mining technologies: Mining Technologies: Area with technical potential for opencast workings (source Coal Resource Map of Great Britain BGS/Coal Authority 1999) Underground mining exploration prospects Good prospects for abandoned mine methane (AMM) (Mine workings not recovered) Resource area for coal mine methane (CMM) (source Coal Authority Underground Licences, May 2002) Extent of underground workings with 500m buffer zone (based on Coal Authority data, May 2002) New Technologies: Area greater than 1200m from surface with potential for CO2 sequestration Area with good coalbed methane (CBM) potential Underground coal gasification (UCG) potential Coalbed methane (CBM) resource area Coal-bearing strata The original methodology is described in the project report which outlines the assessment, development and uncertainties of the methodology which is available as a free download on the BGS website here: http://www.bgs.ac.uk/downloads/start.cfm?id=1712

The 3D Quaternary geology of the area around Thornton, Cheshire

This report summarises the superficial (Quaternary) geology of the area around Thornton Science Park at Thornton-Le-Moors in north Cheshire, with an emphasis on understanding the geological units in terms of potential fluid transport through them. The study utilised existing geological maps and borehole records to construct a 3D geological model of the superficial deposits, covering an area of 63km2. The Quaternary succession in the area is dominated by glacigenic sediments, comprising till (gravelly clay), glaciofluvial deposits (gravels and sands) and lesser amounts of glaciolacustrine clays and silts. The tills and glaciofluvial deposits are intercalated in some areas, with intervals of sand and gravel within the till modelled as lenses. The superficial deposits vary laterally and vertically across short distances, making extrapolation difficult in areas where borehole data are absent. Holocene sediments, comprising tidal flat deposits, peat and alluvium occupy the northern part of the study area forms a tract through the middle of the area. The northern part of the model covers the southern bank of the Mersey estuary where tidal flat deposits, dominated by silt and clay, are mapped/modelled with till underneath. A laterally persistent peat layer within the tidal flat deposits is modelled where proven in boreholes. The River Gowy runs south-north through the middle of the model area to join the Mersey at Stanlow Point. An arbitrary mapped line separates alluvium associated with the River Gowy from the Mersey estuary tidal flat deposits, with which they are transitional. A large area of peat is mapped/modelled at surface in a marshy area in the River Gowy floodplain. Boreholes prove that much of this peat is underlain by alluvium. Bedrock is mapped/modelled at surface in isolated patches, representing bedrock ‘highs’ where superficial deposits are locally absent. There may be other unproven zones of thin or absent superficial deposits in the area that could provide direct connectivity from the ground surface to the underlying Sherwood Sandstone Group bedrock
