Map based index (GeoIndex) geochemical samples

The map shows the location of excess sample materials from the G-BASE (Geochemical Baseline Survey Of The Environment) geochemistry project:- stream sediments, panned heavy mineral concentrates and soils are stored long term in the National Geoscience Data Centre and are available for use in other projects. The Minerals Programme (incorporating the Mineral Reconnaissance Programme) sample collection contains reference samples of drill cores, rocks, tills, soils, stream sediments and panned concentrates. These samples were collected in the period 1974 - to date in mineralised and potentially mineralised areas of the United Kingdom, principally in the northern and western Britain.

本图展示了G-BASE（环境地球化学基线调查）地球化学项目过量样本材料的地理位置：河流沉积物、分选的重矿物浓缩物和土壤被长期储存在国家地球科学数据中心，可供其他项目使用。矿产计划（包括矿产勘查计划）的样本收集包含了钻探岩心、岩石、泥流、土壤、河流沉积物和分选浓缩物的参考样品。这些样品自1974年以来在联合王国已矿化及潜在矿化区域收集，主要位于英国北部和西部。
