吉林省洮南市闹牛山铜矿床（吉林段）地质特征及成因探讨

摘要

Naoniushan copper deposit is located in the border of Jilin and Inner Mongolia, its ore bodies occur in the edges of the volcanic structures and the western fracture of the subvolcanic rocks. Based on both the analyses of the occurrence state of ore body and the deposit genesis, it is considered that Naoniushan copper deposit occurs the outside of volcanic ediifce, and the mineralization is mainly controlled by fracture and ifssure, which belongs to sub volcanic hydrothermal origin. Copper mineralization is shown as the mineralized types of porphyry at depth at the edge of volcanic ediifce. That put forward a new idea of further prospecting in the area in the future.%闹牛山铜矿位于吉林与内蒙古交界处，矿体主要赋存于闹牛山火山机构边部和西侧次火山岩中的构造裂隙中，通过分析矿体的赋存状态和矿床成因，认为闹牛山铜矿在火山机构的外侧，矿化主要受断裂裂隙构造控制，属于次火山热液成因，在火山机构边部铜矿化在深部表现为斑岩型矿化特征，为以后在该地区的找矿提出了新的思路。
