| Popis: | The Sarysu-Teniz watershed is on a large, east-west trending arch in western Kazakhstan, within the Caledonian folded province. The lithologies, thickness, and ages of the main rock units are tabulated. The data are interpreted as supporting the hypothesis that diverse cycles in the development of mobile zones may be identified on the basis of the sequence of igneous formations (both effusive and intrusive), their geochemistry and the associated metallogenesis, as well as by sedimentary relationships. Some data appear to suggest the existence of 1) separate, basic and acidic magma chambers for certain effusive formations, .2) common sources for effusive and intrusive acidic magmas, and 3) notable hybridization and differentiation. Geologic environment also appears to control or be reflected by the composition of magma. Metallogenesis similarly correlates with magma composition including hybridization and differentiation modifications. It seems on the basis of the now available data that prospecting for ce... |
