Soil Parent Material Model (SPMM)

< Back

Dataset Description:

The BGS’s Soil Parent Material Model (SPMM) dataset identifies the original weathered rock or deposit from which the soil has formed.  Parent materials are the basic foundations and building blocks of soil, which influence their texture, structure, drainage, and chemistry.

The SPMM dataset is a 1:50,000 scale vector polygonised dataset containing over 30 rock and sediment characteristics from the BGS Geology 50k geological dataset (DiGMapGB-50).  Simplified classifications of lithological properties are added, with attributes defining texture information, colour, structure, mineralogy, lithology, carbonate content, and genetic origin.
