内蒙古乌拉特后旗潮海地区元素地球化学分布特征及金成矿远景预测

The Elements Geochemical Distribution Characteristics and Gold Mineralization Prospect Forecast in Chao-hai Area,Inner Mongolia

内蒙古乌拉特后旗潮海地区具有较好的成矿前景,在潮海地区通过开展区域1∶5万地球化学测量及重点工作区1∶1万地球化学测量与成矿元素的空间分布特征研究,认为该区寻找Au及多金属矿的潜力较大。通过元素异常特征及传统地质大比例尺填图的综合方法,发现该区Au矿化可能与二长花岗岩区内部的石英脉及寒武系变质岩系密切相关,区内深大断裂亦为其控矿因素。依据元素区域地球化学异常特征,并结合区域大比例尺地质测量、地球物理特征划分出了乌兰敖包和萨音呼都格两个Au成矿远景区。

The preliminary study of the geochemistry features of Chao-hai region was base on 1 ∶ 50 000 and 1 ∶ 10 000 geochemistry survey. Through the study of metallogenic element distribution features,we find that this area has the potrntial of finding Au and polymetallic ore. It shows that the the gold mineralization has the close connection with the Cambrian metamorphic rocks and the quartz vein which inner the monzonitic granite. Deep fracture also for its ore-controlling factors in this area.The authors found out two gold prospecting target areas which are Wulan＇aobao area and Shayinhuduge area,based on the geochemical anomaly characteristics of the element,large scale geological mapping and geophysical characteristics.
