Zhang Xuan Regional Geological and Geochemical Characteristics

摘要

Zhang Xuan region's landscape is the result of the Mesozoic tectonic evolution. Curtain shell movement is the dominant factor in the evolution of the regional geological environment. Zhang Xuan region due to mantle deep effect of in vitro, and superposition of ductile shear zone of the cutting, lead to lung on mantle and magma activity, through the analysis of the geochemical elements of Zhang Xuan region, confirmed Zhang Xuan region has centered on alkaline complex rock mass is the unification of the differentiation and evolution characteristics of trace element. Analysis of mineral superimposed on the space relation, has also a lot of help to the deep prospecting.
