Application of remote sensing technique to geological survey abroad:A case study of Great Dyke,Zimbabwe
摘要
Abstract
The Great Dyke in Zimbabwe, which possesses abundant platinum, palladium, gold, chromium, nickel, copper and some other resources, is a major intrusion of mafic and ultramafic rocks formed at 2. 5 Ga and one of the key regions for mineral exploration abroad. In order to attain the aim of"going out" for China’ s mineral exploration and provide basic geological information of geological survey and mineral exploration in the area of the Great dyke, the authors carried out the systematic interpretation of geometric elements and geological characteristics of the Great Dyke in Zimbabwe based on the ETM+ data and verified the division of the magma chamber of the Dyke. Combined with the ZY-1 02C high spatial resolution satellite data, the authors identified and interpreted the shape, lithology, interior structures and mining activities of the Selukwe Subchamber. The results achieved show that, because of the difference between the west and east host rocks, the Selukwe Subchamber underwent deformations of different intensities. The ultramafic layers should be regarded as the major layers for the chromite exploration. Furthermore, the authors have discussed the method of "five scales" of the remote sensing technique in the geological survey abroad and provided the technical support for the remote sensing application.关键词
