华南印支期铝质A型花岗岩的判别、成因及构造环境
Discrimination, Genesis and Tectonic Setting of In-dosinian Aluminum A-type Granite in South China
摘要
Abstract
The traditional meaning of the A-type granite on the chemical composition can be divided into alkaline A-type granite (AAG) and aluminum A-type granite (ALAG).Aluminum A-type granite (ALAG) belongs to a subtype of A-type granitoids. Along with the deep-going research of indosinian aluminum A-type granite in southern China, it is becoming more and more attention. The unique mineralogy feature and geochemical charac-teristics of ALAG is summarized to discuss the method for discriminate the ALAG from other type granitoid. It then analyzed material source, petrogenesis and tectonic settings of the Indosinian ALAG in South China. It is shown that indosinian aluminum A-type granite in southern China from different degree of partial melting of huaxia plot old metamorphic sedimentary rocks, possible contaminated the basic components of mantle in the pro-cess of its formation;tectonic setting is mainly controlled by the subduction of the ancient Pacific plate, formed at post orogenic stage, but should also be impact collision process for the indosinian block and South China conti-nental block.关键词
