中文摘要: |
根据板块活动论的观点,在野外地质调研及室内研究工作的基础上,结合以往的工作,划分出7个主要类型的金矿,并分别讨论了各类金矿的时空分布特征,通过对域内金矿的多学科综合性研究,总结了域内构造演化与金矿的时空分布的关系。 |
英文摘要: |
According to the viewpoint of "open-and-close" of plate tectonics, the tectonic framework of Tethyan domain of southwest China is briefly introduced, and an inquiry into the temporal and spatial distribution of Au-deposits has been made on the relationship between the Tethyan evolution and Au ore deposits.The suture zones and continental marginal sag zones dominate most of the Au deposits in the domain of southwest China. Au deposits formed under the regime of extension are related to the ophiolite suite zones and basic-ultrabasic rock zones. Au deposits formed under the regime of collision compression are associated with intermediate-acid intrutions,volcanic subvocanic magma (thermal spring) activities, ductile (brittle) shear zones and thrust tectonics. |
