Data arising from drilling investigations in the Loch Borralan intrusion, Sutherland, Scotland

In 1988, following promising indications from commercial studies in Canada, MRP investigations for the platinum group elements (PGE) were directed towards the mafic constituents of alkaline intrusive suites in Scotland. The results of studies on the Borralan intrusion are contained in this data release. The investigations took place in two phases. Initially, archived borehole cores from 37 shallow vertical boreholes, drilled in 1979 as part of an investigation by BGS into the phosphate potential of the Borralan intrusion, were examined and sampled for PGE analysis (Volume 1). Subsequently, following the discovery of localised PGE enrichment in these samples, a drilling project directed specifically towards the investigation of these elements in the Borralan intrusion was carried out. The data, compiled from geochemical, geophysical and mineralogical studies of this drillcore, are presented in Volume 2.
