近年来，虽然秦岭造山带的研究取得了重要进展，但对于分布广泛的南秦岭地区变质作用的研究非常薄弱。仅在中国变质地质图和陕西省区域地质志中指出，该区的变质作用以佛坪地区为中心发育递增变质带，最高为十字石蓝晶石级，主变质期为海西期。本课题组最近对南秦岭造山带... In recent years, although the research on the Qinling orogenic belt has made significant progress, the study on the metamorphism of the widely distributed South Qinling Mountains is very weak. Only in China metamorphic geological map and regional geology in Shaanxi Province pointed out that the metamorphism of the area to Foping area as the center to develop increasing metamorphic belt, the highest for the spar-kyanite grade, the main metamorphic period Hercynian. Our group recently on the South Qinling orogen ...
