大比例尺勘查地球化学找矿信息提取集成与成矿预测——以内蒙古乌拉特后旗查干德尔斯大型钼矿为例
Extraction and Integration of Geochemical Prospecting Information in Large-scale Exploration and Metallogenic Prediction:Example from the Chagandeersi Large Mo Deposit in Urad Houqi,Inner Mongolia
【摘要】 在综合研究成矿地质条件的基础上,深入剖析1∶2.5万沟系土壤地球化学特征,准确提取、集成地质-地球化学找矿信息,识别主成矿元素,判别矿化类型,圈定找矿有利部位,经钻探验证,发现内蒙古乌拉特后旗查干德尔斯大型隐伏钼矿。笔者通过典型案例分析,重点论述勘查地球化学找矿信息在成矿预测中的作用,为寻找隐伏矿床提供参考。
【Abstract】 Based on the comprehensive study of metallogenic geological conditions,1∶25000 soil geochemistry characteristic of drainage system has been analyzed,the geological and geochemical prospecting information has been extracted and integrated,the main ore-forming elements have been identified,and the favorable location of ore prospecting has been delineated in this paper.Then,the Chagandeersi large concealed molybdenum deposit has been discovered by the exploratory drilling in Urad Houqi,Inner Mongolia.The application of geochemical prospecting information in metallogenic prognosis has been discussed emphatically,providing a reference for prospecting the concealed ore deposits.
