A parent material is a soil-science name for a weathered rock or deposit from, and within which a soil has formed.

In the UK, parent materials provide the basic foundations and building blocks of the soil, influencing their texture, structure, drainage and chemistry.

Soils are the result of weathering processes that occur on the Earth’s surface where the atmosphere meets the geosphere and hydrosphere. We live in this ‘critical zone’ relying on our soils to grow our food and sustain the biodiversity and health of our environment.

The Soil Parent Material Model details the distribution of physiochemical properties of the weathered and unweathered parent materials of the UK to:

  • facilitate spatial mapping of UK soil properties
  • identify soils and landscapes sensitive to erosion
  • provide a national overview of our soil resource
  • develop a better understanding of weathering properties and processes

There are two versions of the Soil Parent Material model available:

  • A licensable, 1:50 000 scale, version containing over 30 rock and sediment characteristics built upon the standard BGS Geology 50k geological dataset, adding simplified classifications of lithological properties. The attribute content includes a range of texture information, colour, structure, mineralogy, lithology, carbonate content and genetic origin.
  • A free, 1 kilometre resolution model detailing 6 basic parent-material parameters (derived from the 1:50 000 scale version). The data is exactly the same as that used in the mySoil application.
