FIND - Geology Maps - Large & Small Scale Software

Modern large scale (1: 10 000) and small scale (1: 50 000) maps commonly show up to five themes of geological information:

• Faults and rock segments

This layer is made up of linear features representing faults, rock units, fossil horizons, landforms and structural features.

• Artificial ground

Artificial ground is a term used by the BGS for those areas where the ground surface has been significantly modified by human activity. Whilst artificial or man-made ground is not part of the `real geology` of bedrock and superficial deposits it does affect them. Near surface ground conditions are very important to development so artificial ground needs to be recorded.

Artificial ground includes:

• Landslip deposits

Landslip deposits are primarily superficial deposits that move down slope, resulting from gravity. Caution should be exercised when building on a landslip deposit because of the potential hazard caused by ground instability.

• Superficial deposits

Superficial deposits (formerly known as `drift` by the BGS) are the youngest geological deposits, formed during the most recent period of geological time. Most of these superficial deposits are unconsolidated sediments such as gravel, sand, silt and clay forming relatively thin, often discontinuous patches or larger spreads.

• Bedrock

Bedrock geology (formerly known as `solid` geology by BGS) is a term used for the main mass of rocks forming the Earth. Bedrock is present regardless of whether it is exposed at the surface in outcrops or is concealed beneath superficial deposits or water.

FIND does not interpret the geological information in any way. If you wish to find out further information or buy a detailed report please contact the BGS directly.
