摘要
以板块理论为指导,在前人三级大地构造单元划分的基础上,对锦屏山地区构造单元进行四级构造单元的划分;结合扬子西缘的地质构造演化过程,分析不同时期构造构作用与区内成矿的关系,从成矿物质来源、成矿作用、控矿作用和成矿的时空分布等方面总结锦屏山地区的区域成矿规律,提出区内重要矿产的找矿方向。
Guided by the plate theory and based on the previous three-level tectonic unit division,the tectonic units in Jinping Mountain area are divided into four-level tectonic units.Combined with the geological and tectonic evolution process of the western margin of Yangtze River,the relationship between tectonic tectonism in different periods and mineralization in the area is analyzed from the aspects of the source of ore-forming materials,mineralization,ore-control and temporal and spatial distribution of mineralization This paper summarizes the regional metallogenic regularity of Jinping Mountain area,and puts forward the prospecting direction of important minerals in the area.
