| Abstract: | A map depicting predicted classes of soil magnetic susceptibility in Angola was produced. The map is based on a classification
system for the susceptibility of tropical soils set up by the authors and a 1:2,000,000 scale FAO soil map. Statistical data
of two large groups of parent rock—ultrabasic, basic and intermediate igneous rocks on the one hand and acid igneous rocks
and some slightly metamorphosed rocks and clastic sediments on the other—had been linked to three associated degrees of weathering.
These determining factors were used to classify Angolan soils, and the overall method is semi-quantitative. The resulting
map shows that easily available pedological information as given by FAO soil maps is generally appropriate to predict soil
magnetic susceptibility. Potential metal detector performance failures may be predicted. The resulting information is a useful
tool for planning the use of appropriate techniques in landmine clearance operations. |
