Abstract:This paper is based on the latest achievements of regional geological survey and mineral exploration, combined with the comprehensive analysis of the geotectonic background, gravity field, tectonic unit and the rock- and ore-controlling structural characteristics in important deposits (fields), we determine the transform like fault in Northern Jiangxi Province, and its formation mechanism and rock- and ore-controlling role are also explored theoretically. The result shows that that transform like fault which is a set of lateral faults located above the subduction zone of the ocean crust in southern China develops in the structural unit of NEE - NE direction of the upstroke disk, and is affected by different vertical subduction rates and deep mantle uplift vertical transform like fault. It matches the unit boundary fault with transformed properties along its horizontal and vertical displacement, and it has its special rock- and ore-controlling mechanism.
