闽西南地区印支期隆起-伸展构造的厘定及其控矿作用

On Confirmation of the Indo-Sinian Uplift and Extensional Structures in Southwestern Fujian and Its Control of Mineralization

在闽西南地区隆起-伸展构造主要活动于印支期,经历了挤压隆起和伸展拆离过程,以拆离体系极为发育为特征,形成的构造形式较为多样,对该区域的矿产分布具有明显的控制作用。

The uplift and extensional structures in Southwestern Fujian mainly develop in the Indo --Sinian period and undergo the processes of the extruding uplift and the stretch decoupling, which are characteristic of the evolution of the decoupling system and the many structural forms. The uplift and extensional structures have an obvious controlling action for the distribution of mineral ores in the surveyed area.
