From July 1973 to February 1975, a reconnaissance stream sediment sampling survey was undertaken on the western half of the Cambrai 1 :63, 360 sheet (Figure 1) which is the Cambrai 1;50 000 geological sheet area, and covers the Cambrai A and Cambrai C subdivisions 0 The survey is part of a programme to provide geochemical information and to pinpoint areas suitable for follow up work, on the closely populated ADELAIDE 1;250s000 sheeto Preliminary work for this project is described in a report by Sibenaler & Rogers (1974). The sparsely drained eastern half of the Cambrai sheet, covered mainly by Tertiary and Recent sands and clays, was not sampled. About sixteen hundred samples were taken just above stream junctions and at intervals of five hundred metres, at a depth of twenty centimetres. The samples were then sent to AMDEL where the .-80 mesh BoSoSo fraction was analysed for Cu. Pby Zn and Au using atomic absorption analysis, and W9 Mo, Nb, Co and Mn using semi quantitative emission spectroscopy. To help, designate anomalous areas, the results were statistically analysed and computerized to produce rolling mean maps for Cu, Pb and Zn, showing local deviations from the regional trend.
