摘要
通过地质、岩石学及地球化学研究,认为秦岭造山带佛坪地区印支期花岗岩是基性岩浆和酸性岩浆混合的产物,属岩浆混合型(H型)花岗岩;佛坪地区在秦岭主造山过程中曾发生强烈的壳慢相互作用,是一个深层岩浆活动中心。
Geological, petrological and geochemical studies show that the Indo-Chinese epoch granites in Foping area, Qinling orogenic belt, are hybrid products of basic magma and acid magma, and are hybrid type (H type) granite. Intensive crust-mantle interaction occurred in Foping area in the main mountain-building period of Qinling, and the area was a deep magmatic activity center.
