Surface Geochemistry Samples (being Superceded by GEOCHEMISTRY)

dataset: GCHEM
Surface Geochemistry Samples is derived from Minerals and Petroleum's SITES Oracle RDBMS. Data have been obtained from company reports of expired mineral Exploration and Mining Licences since 1965. A surface sample is typically taken to comprise a sample taken from the weathered profile, and which is the only sample taken at that location. It may be a soil or it may be a sediment taken from an active stream bed. Though most soil samples are taken from the B- or C-horizon (approx. 10-40 cm depth) the dataset may, for example, include a sample taken from 2 m depth and obtained by augering. There is, thus, a continuum between surface geochemistry and boreholes datasets.
