BGS rock classification scheme. Volume 4, classification of artificial (man-made) ground and natural superficial deposits applications to geological maps and datasets in the UK: British Geological Survey, Research Report RR/99/004 / A.A. McMillan & J.H. PowellBooks/Monographs
This report describes the BGS classification schemes for drift of Pleistocene and Recent age comprising artificial (man-made ground) and natural superficial deposits. They are designed to be used and interpreted by both geologists and non-geologists to allow thematic material comprising identified classes of superficial deposits to be extracted from geological maps and other data-sets. The schemes can be developed further to other classes of materials particularly from overseas tropical and sub-tropical land, shelf and deep-sea areas. In Britain traditional onshore investigations of the drift have employed a morphogenetic and lithogenetic terminology resulting in an amalgam of terms with a dominantly genetic basis. This report adopts a similarly genetic approach, however it is recognised that an objective description involving sedimentological, structural, physical and chemical criteria to construct lithofacies associations is desirable and reference to such schemes is made where appropriate. The report, issued here as BGS Research Report RR 99-04, includes 26 tables and 16 figures.
