National Soil-Parent Material

The National Soil Parent Material dataset is a GIS describing the geological material from which topsoils and subsoils (A and B horizons) develop (i.e. from the base of pedological soil down to c. 3m). These deposits display a variable degree of weathering, but still exhibit core geological characteristics relating to their lithologies. The dataset covers England, Scotland and Wales and characterises parent material lithology, texture, mineralogy, strength and a range of other soil/parent related properties.

国家土壤母质数据集系一项地理信息系统数据，详细描述了形成表土和底土（A层和B层）的地质材料（即从土壤发生学的底部至约3米深度）。这些沉积物呈现出不同程度的侵蚀，但仍保留了与其岩性相关的核心地质特征。该数据集涵盖了英格兰、苏格兰和威尔士，并对其母质岩性、质地、矿物学、强度以及其他一系列土壤及母质相关属性进行了表征。
