TECTONIC SYSTEM ANALYSIS OF THE FENGHUANG SHAN INTRUSIVE AND ITS EMPLACEMENT
-
Abstract
In this paper, a discussing is made of the location of the Fenghuanshan pluton, in the regional tectonic regime, tectonic evolution before and after the emplacement and the dynamic conditions for the magma emplacement. The foliations and lineations both in the pluton and in the contact zone are systematically studied by measuring their magnetic fabrics, microstructures, strained inclusions and X-ray analysis of rock fabrics. As a result, it leads to the conclusion that there occurred not only dilatation due to the emplacement but also rotation of the intrusive in the late stage of the emplacement, which was controlled by the NNE sinistralshear.-
