【摘要】 总结了辽宁省盖州市卧龙泉地区约1 000 km2区域内岩浆热液型金矿的成矿规律,建立了金矿预测模型。研究结果显示:研究区内已知金矿的有利赋矿地层为辽河群盖县组,控矿岩体为印支期二长花岗岩——卧龙泉岩体,北西向与北东向断裂交汇处为成矿有利部位。在此基础上,利用特征分析方法、数量化理论Ⅳ等数学方法建立了金矿预测的数学模型,对研究区内的金矿成矿远景区进行了预测。根据计算结果优选出61个成矿可能性较大的预测单元,并最终圈定成矿远景区9处,其中Ⅰ级成矿远景区3个,Ⅱ级成矿远景区2个,Ⅲ级成矿远景区4个。更多还原

【Abstract】 In this paper,the metallogenic regularity of magmatic hydrothermal type gold deposits in Wolongquan area(ca.1 000 km2),Liaoning Province,is studied and the prediction model of gold deposits in this area is summarized.The results indicate that the main ore-bearing strata of gold deposit are the Gaixian Formation of the Liaohe Group,the ore-controlling magmatic rock body is the Indosinian Wolongquan monzonitic granite intrusion,and the intersection part of the NW-trending fault with the NE-trending fault is the favorable ore-forming position.Based on these studies,the mathematical model for prediction of gold deposits in this area is established by the characteristic analysis method and quantification theory Ⅳ.According to the model established in this paper,sixty one prediction units which have large metallogenic possibility have been proposed,and nine gold metallogenic prospecting areas are determined,including three Ⅰ-grade,two Ⅱ-grade and four Ⅲ-grade areas.更多还原
