大兴安岭北部宝兴沟金矿床地质地球物理特征与找矿模型
Gological and geophysical characteristics and prospecting model of Baoxinggou gold deposit in northern part of Great Xing'an Mountains
摘要
Abstract
This paper aims to investigate the geological and geophysical characteristics of Baoxinggou gold deposit in the northern of the Great Xing′an Mountains for guiding mineral exploration better.The study establishes a suitable exploration model by further summarizing its geological and geophysical char-acteristics,conducting systematic measurements of physical properties and comprehensive geophysical profiles.The results indicate that mineralized bodies mainly occur at the contacting area between diorite(porphyrite)veins and the 22nd Station strata,and the strata is superior to the rock masses.The high magnetic tapes zone in low magnetic area,and the low resistivity zone within high resistivity are condu-cive to mineralization,while the gold mineralization body exhibits obvious low resistance and high polari-zation characteristics relative to the surrounding rock.There is larger magnetic anomaly gradient change with alternating positive and negative phenomena at the ore bodies,and the positive anomaly appears on one side of the hanging wall with obvious peak values at the top of the ore body and vein rocks,and the side with small gradient changes indicates its dip direction.关键词
