摘要
为了深度挖掘桃山铀矿田的资源潜力,在桃山地区开展了综合物探测量,结果表明,CSAMT测量能反映出断裂及裂隙密集带的特征,特别是断裂的影响宽度、深度、两盘结构变化等;磁法测量能圈定与铀成矿有紧密关系的黑云母二长花岗岩的分布范围。根据区内已知铀矿床的的分布,分析了铀矿床的地球物理特征,总结了地质—地球物理找矿模式,预测了铀找矿有利地段,取得了好的勘查成果。
In order to lap the potential of the Taoshan uranium ore fieht, the authors conducted integrated geophysical survey in Taoshan area. The inversion result of CSAMT can indicate the characteristics of the faults and the fractured zones in the subsurface, especially the width, depth, strata and lithology of the faults. Magnetic survey can delineate the monzontie granite zone which is closely related to the uranium deposit. A geological-geophysical model was formulated for this ore district and the prospecting target of the uraium deposit area was delineated. It is shown that the resuhs obtained by the authors are valuable for further expluration.
