中文摘要:基于最新的区域地质调查、矿产勘查成果资料,结合赣北地区大地构造背景、重力场、构造单元及重要矿床(田)控岩控矿构造特征的综合分析,厘定了赣北地区类转换断层,并探讨其形成机制与控岩控矿作用。结果表明,该类转换断层是一组位于华南洋壳俯冲消减带,受纵向俯冲消减速率不同和深部地幔隆起垂直转换断层影响,在仰冲盘NEE向—NE向构造单元中发育的横向断层,其与单元边界断层相匹配,沿着断层的水平和垂向位移转换了性质,具有特殊的控岩控矿作用。
中文关键词:类转换断层  垂直转换断层  控岩控矿作用  赣北地区

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.
keywords:Transform like fault  Vertical transform fault  Rock- and ore-controlling role  Northern Jiangxi Province.
