The source system of Mesozoic magmatism in Middle and Lower Yangtze Valleys and adjacent Areas—a geochemical tracer study
Tóm tắt
The mechanism that controls regional mineralization must be governed by a series of geochemical reactions in relation to the source system of magmatism. In this respect, the geological bodies must have been overprinted by various kinds of tracers in terms of either chemical elements or isotopes. For this reason, the problem may be better approached by treating the lithosphere as a whole with due considerations given to the various tracer elements and isotopes and the various media of the magmatism (magmatic as well as sedimentary rocks). Presented in this paper are the results of this attempt based on a great wealth of available data concerning the source system of Mesozoic magmatism in the Middle and Lower Yangtze Valleys and adjacent areas.
