This document is the drillers log of strata encountered during site investigation work. The log was made in the field during drilling at Prees, Shropshire on 8th to 10th January 2020. The log includes basic information on lithology and drilling equipment used and depths of the individual core runs.
This British Geological Survey (BGS) regional marine sampling survey took place from August to December 1985 on board the British Magnus. Seabed samples and cores were collected using Shipek grab, Vibrocorer, Gravity corer, rock drill and sediment dredge. These data are archived by BGS. Trials of a camera grab were also undertaken. Technical details of the survey are contained in BGS Internal Reports WB/85/12-14, 16, 17, 19, 21 & 23.
This British Geological Survey (BGS) marine sampling survey took place in August/September 1979 in the North Sea from a Zodiac. The aim of this dive survey was to collect samples for analysis to evaluate possible downstream and offshore movement of gold from the River Helmsdale. Seabed samples were collected by divers. These data are archived by BGS. Technical details of the survey are contained in BGS Marine Geology Internal Report WB/MI/79/10.
This British Geological Survey (BGS) marine geophysical and sampling survey took place in January 1973 in the Firth of Forth on board the Minto. Seabed samples were collected using Shipek grab and Gravity corer. Subsurface data were gathered trialling Pinger and Sparker instruments. These data are archived by BGS.

This marine sampling survey took place on 7 January 2013 on board the Northern Lighthouse Board vessel NLV Pole Star. Cone penetration testing was conducted by Marine Sampling Holland on behalf of the British Geological Survey (BGS) at 5 sites in Loch Linnhe in preparation for Rock drill trial survey 2013/2.

Contract: Shallow. FY 2012/13. Contractor: EMU.
The Nirex Digital Geoscience Database (NDGD) holds extensive sets of data describing geoscientific, geographical, hydrogeological and logistical aspects of the Sellafield area in western Cumbria region. Some datasets comprise unmodified field data (as collected, measured or observed in the field). Others include values assessed during laboratory analysis or testing. Derived or interpolated information, resulting from modelling activity or the integration of several datasets, also accounts for a significant portion of the NDGD holding. The data consists of mainly borehole derived information including Borehole location and survey information, Sample location information, Logistics, Geological, geophysical (including borehole geophysical logs) and geotechnical borehole Geology datasets and Hydrological, hydrogeological and hydrochemical borehole datasets (though information from the down-hole monitoring strings and most groundwater related information is not held in the NDGD). The NDGD holds all of the raw and processed digital data arising from the Nirex (Nuclear Industry Radioactive Waste Executive) Sellafield Geological investigations boreholes drilled during their investigation programme into the suitability of Sellafield as a site for the disposal of intermediate and long-lived low level radioactive waste between 1989 and 1997. The ownership of Nirex (Nuclear Industry Radioactive Waste Executive) was transferred from the nuclear industry to the UK Government departments DEFRA and DTI in April 2005, and then to the UK's Nuclear Decommissioning Authority (NDA) in November 2006.
The Bedrock summary lithologies dataset is digital geological map across the bulk of the UK Continental Shelf (UKCS), for areas up to a water depth of 200m, which groups the bedrock lithologies (rock types) into classes based on similar engineering geology characteristics. The map is derived from the 1:250,000 scale digital bedrock map of the UKCS, called DiGRock250k, which is available separately from the BGS. The map was produced in 2014 in collaboration with, and co-funded by, The Crown Estate as part of a wider commissioned project to assess seabed geological constraints on engineering infrastructure across the UKCS. The divisions on the map combine the bedrock formations into 8 classes (with several subdivisions) of similar strength and lithological variability, each with a ‘Category’ title that summarises their main lithological character: Class1 – Igneous; Class 2 - Tertiary Sandstone and Limestone; Class 2.5 - Tertiary Sandstone and Limestone Interbedded; Class 3 - Tertiary Mudstone; Class 4 - Mesozoic Sandstone and Limestone; Class 4.5 - Mesozoic Sandstone and Limestone Interbedded; Class 5 - Mesozoic Mudstone; Class 6 – Chalk; Class 7 – Metamorphic; Class 8 - Palaeozoic Sedimentary. The data are held by the BGS as an ESRI ArcGIS Shapefile.
