一、华南存在海西旋回的花岗岩 华南是否存在海西旋回的花岗岩?是中国地质界所关注的重要课题。本文在发现华南海西地槽褶皱带的基础上,首次系统讨论了华南海西花岗岩类有关的地质问题。 花岗岩类岩石,在华南分布广泛、活动频繁、作用复杂,并蕴藏有W、Sn、Cu、Mo、 First, the existence of South China Sea Hercynian granites South China Sea Hercynian cyclones? It is an important issue of concern to the Chinese geology. Based on the discovery of the Xikou geosynclinal fold belt in South China, the geological problems related to the Hercynian granitoid are systematically discussed for the first time. Granitic rocks are widely distributed in southern China, with frequent activities and complex functions. They contain W, Sn, Cu, Mo,
