Map based index (GeoIndex) mineral reconnaissance programme borehole rock samples

This layer of the map based index (GeoIndex) providex an index to 17,500 borehole rock samples (drillcore) from the Mineral Reconnaissance Programme (MRP) and related studies. The UK Government's Department of Trade and Industry (DTI) funded BGS to provide baseline information on areas prospective for the occurrence of metallic minerals in Great Britain. This programme, known as the MRP, ran continuously from 1973 to 1997 and covered particular locations across Great Britain. It was designed to stimulate private sector exploration and to encourage the development of Britain's indigenous mineral resources. Under the programme a number of boreholes were drilled to gather information.

本图基索引层（GeoIndex）提供对17,500个来自矿物勘查计划（MRP）及相关研究的钻孔岩样（岩心）的索引。英国政府贸易工业部（DTI）资助英国地质调查局（BGS）提供有关大不列颠地区具有金属矿物潜在发生的基准信息。该计划，即MRP，自1973年起持续运行至1997年，覆盖了大不列颠特定区域。其旨在激发私营部门的勘查活动，并鼓励英国本土矿产资源的开发。在该计划下，钻探了多个钻孔以收集信息。
