摘要
江西相山火山盆地是我国火山岩型铀矿的重要产地,其地形复杂,切割强烈,矿藏分布不均,各矿区具有不同的地球物理特征。利用相山地区重力资料,结合磁法、MT数据以及相关地质资料,运用地球物理反演,比较了邹家山与牛头岭矿床,并用钻孔、遥感以及地质资料做了验证。推测相山矿田存在东、西双岩浆活动中心,邹家山与牛头岭之间存在大型断裂带,两边各有次生断裂,两地矿床在成矿地质环境、物质来源以及成矿深度上存在差异。
The Xiangshan volcanic basin is an important locality of uranium ore in China. It has a complex terrain and strong incision,where mineral resources are unevenly distributed. Every deposit of this orefiled should have distinct geophysical characters. By using gravity data,combined with magnetic and MT data as well as relevant geological literature,this work compared the Zoujiashan and Niutoushan deposits in this area through geophysical inversion. The results show that these two deposits are different in some aspects,which is verified drilling,remote sensing and geological data. It is speculated that there exist two igneous activity centers in the Xiangshan region. A large fault zone is present between the two mountains,Zhoujiasan and Niutoyuling,with secondary faults on either side. The two deposits are also different in the metallogenic geological environment,source material and the depth of mineralization.
