During the period 1982-86 a team of geologists from the British Geological Survey carried out a programme of regional geological mapping and geochemical exploration in collaboration with the Zimbabwe Geological Survey under a Technical Co-operation agreement supported by the UK Department for International Development (DFID) (formerly ODA). Three regions of Zimbabwe were mapped and the results of the stream sediment geochemical surveys were presented as three reports.
These reports are available through the BGS sales desk (Fax: +44 (0)115-936-3488).
This work pre-dated the desktop PC era and the analytical data was stored on a Cifer 1880 microcomputer and PDP11 magnetic tapes. These data have recently been transferred to PC format and stored as a CD-ROM database. Some of the XRF data was lost from the original PDP11 tapes and these results are now represented as absent data (-1). Several erratic Ta and Ba highs from the Rushinga and Nyamapanda data set have also been replaced with -1. In the original reporting it is believed that these records were removed from the data set and this accounts for the difference in the number of samples reported here and those used in the technical report.
