江西赣东北某金矿赋存规律分析及找矿方向

摘要

赣东北地区大地构造环境复杂,成矿地质背景优越,金矿床类型多样,其中韧性剪切带控制的蚀变岩金矿尤为突出,找矿潜力大.通过对赣东北某金矿的区域地质背景、矿区地质特征、含金的韧性剪切带的分布特征进行综合分析,并对近年来矿山探矿资料的整理、分析,依据含金韧性剪切带的分布和产出规律建立空间模型,预测成矿的地段,提出下一步的找矿方向.%The northeastern Jiangxi area has a complicated topography, with sound geological ore-forming background and various types of gold deposit, dominated by altered rock gold deposit which is controlled by ductile shear belt. This area has good prospecting potential. By a general analysis on the geological background,features of the gold deposit and distribution of the ductile shear belts of the area,as well as mine exploration data for recent years,we set up a space model according to the distribution of gold-bearing shear belts to make metallogenic prediction/prognosis and propose a prospecting direction for the next stage.
