大冰湖沟斑岩型钼矿地质与地球物理综合找矿

摘要

Dabinghugou molybdenum deposit is a typical porphyry molybdenum deposit in eastern Jilin and Heilongjiang provinces. On the basis of previous data to porphyry molybdenum deposit, the authors analyze the relationship between geological mineralization and geophysical field of porphyry molybdenum deposit. Through the study of gravity, airborne magnetic and electrical data of Dabinghugou molybdenum deposit, the authors put forward that the porphyry molybdenum deposit takes the Yanshanian magma as carrier, which expresses the characteristics of low gravity, low aeromagnetic, low resistivity and polarization based on known geological condition.%大冰湖沟钼矿是吉黑东部典型的斑岩型钼矿之一.在借鉴以往资料对斑岩型钼矿的研究基础上,系统分析了斑岩型钼矿的地质成矿与地球物理场之间的关系.通过研究大冰湖沟钼矿的重力、航空磁法及电法资料,根据已知地质矿产情况,总结出该斑岩型钼矿以燕山期岩浆为载体,表现为区域低重力、低航磁和低阻低极化的找矿特征.
