Collections of miscellaneous items mainly of semi-current value, including some field observations supplementary to 1:10560/1:10K mapping, arranged on 1:10K or One-Inch sheet basis. Set up in 1950's filing miscellaneous records for Scotland and Northern England. Records of archival value for permanent retention being transferred to Land Survey Archives (LSA). Indexed in the Land Survey Record Index (LSRI).

The BGS collection of 1:10 560 / 1:10 000 National Grid Series geological maps. These maps are based on the Ordnance Survey National Grid series of maps, which are defined by the 10 km intervals of the larger 100 km square identified by a specific two-letter code. Each map is thus denoted by a unique reference, e.g. SP 29 NW. SP=100 km square; 29=10 km square; NW=5 km square. Since field mapping is generally undertaken at the scale of 1:10 000 (or equivalent), these maps are the largest-scale main series of geological maps that BGS holds. A small number of remote areas were mapped at 1:25 000 scale, the subsequent maps are also at 1:25 000 scale and are included in this series. The equivalent to the National Grid Series prior to the 1960s is the County Series (at 1:10 560 scale). In the 1960s, this series started to be replaced by 6 inches to 1 mile (1:10 560 scale) National Grid sheets based on the four quadrants (NW, NE, SW, SE) of a 10 km Ordnance Survey National Grid square. Areal coverage provided by the National Grid series of large-scale maps is limited in extent and the preceding County series of six-inch maps can still be the most up to date map available for some areas. Geological maps represent a geologist's compiled interpretation of the geology of an area. A geologist will consider the data available at the time, including measurements and observations collected during field campaigns, as well as their knowledge of geological processes and the geological context to create a model of the geology of an area. This model is then fitted to a topographic basemap and drawn up at the appropriate scale, with generalization if necessary, to create a geological map, which is a representation of the geological model. Explanatory notes and vertical and horizontal cross sections may be published with the map. Geological maps may be created to show various aspects of the geology, or themes. The most common map themes held by BGS are solid (later referred to as bedrock) and drift (later referred to as superficial). These maps are, for the most part, hard-copy paper records stored in the National Geoscience Data Centre (NGDC) and are delivered as digital scans through the BGS website.

The Marine Reports Archive held by BGS includes published and unpublished reports created by BGS and acquired from various sources. The reports which date from the 1960s onwards include the BGS Marine Reports Series, Marine Commercial reports and associated records, Palaeontology reports and other specialist reports. Examples of report types are data acquisition and processing reports, site investigation reports and interpretation reports. The reports are primarily for the UKCS (United Kingdom Continental Shelf). The coverage of some reports is the entire UKCS whilst other have only regional or very localised extent. The reports are applicable to a wide range of uses including environmental, geotechnical, geophysical and geological studies.

A collection of regional geochemical data, mainly from stream sediment surveys, gathered from many BGS overseas projects since 1960s. Some areas are well covered and well documented with data available digitally on CD-ROM. Projects from 1960s and 1970s generally have no digital data and information exists only in paper form.

Data from geophysical surveys in many African countries carried out by the British Geological Survey for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.

Data on the physical properties (transmissivity, storage coefficient, porosity and permeability) of aquifers in England and Wales. Compiled by BGS staff from paper records of field and laboratory testing held by BGS, the Environment Agency and other organisations. Contains summary data on approximately 20,000 pump tests at over 2000 discrete locations. Raw data may be available on request. The majority of BGS and EA pump test data is included for both major and minor aquifers, but in minor aquifers this is complemented by data on specific yield. Laboratory determinations of porosity and permeability are limited to open file BGS data only. All data subject to similar processing and interpretation, but raw data highly variable.

The Marine Maps and Chart Archive held by BGS contains maps created by BGS (the majority of which result from BGS offshore mapping projects) and also maps acquired from various other sources (e.g. UK Hydrographic Office and MCA Civil Hydrography Programme survey charts). The maps which date from the 1960s onwards are very variable in subject type and scale ranging from survey navigation to geological interpretation. The maps are primarily for the UKCS (United Kingdom Continental Shelf). The coverage of some map types is the entire UKCS whilst other have only regional or localised extent. The maps which are a mix of paper and digital are applicable to a wide range of uses including environmental, geotechnical, geophysical and geological studies. range of uses including environmental, geotechnical, geophysical and geological studies. Scanned maps can be viewed via the BGS maps portal http://www.bgs.ac.uk/data/maps.

Data from geophysical surveys in many South American and Caribbean countries carried out by the British Geological Survey for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.

The collection, amounting to c.6,000 records, consists of reports and data relating to geochemical sampling, geophysics, drilling and field mapping deposited by mineral exploration companies dating from c.1960 onwards. Major accessions include records of Mineral Exploration Incentive Grant Act (MEIGA) and reports and plans of Exploration Ventures Ltd (EVL) relating to NE Scotland. Indexed in Land Survey Record Index Database (LSRI).

Data from geophysical surveys carried out by the British Geological Survey in many countries in the Middle East, the Indian sub-continent and Indo-China for different agencies. The surveys range from regional gravity and airborne magnetic mapping to targetted surveys for mineral and water. Individual surveys do not yet have metadata entries: this entry describes a notional database that represents all geophysical surveys carried out within the region.
