摘　　要：新开金矿区地处燕山期麻棚岩体为中心的金、银、钼、铅锌多金属成矿带内,区内以中太古代大石峪片麻岩、坊里片麻岩、蔡树庄片麻岩及新太古代岗南片麻岩为典型代表。论文对新开金矿床地质特征、成矿控制因素等方面进行了详细分析研究。结果表明:新开金矿含金矿化蚀变带赋存在黑云斜长片麻岩中,从成因上讲,燕山期中酸性岩浆侵入活动是矿床形成的主导因素,属中低温热液充填型-石英脉型金矿床;构造是成矿的重要控制因素,控制了岩浆的侵入及其成矿岩体和矿体的形成及其空间展布。该区成矿在空间分布上与矿区浅成相中酸性岩关系最为密切。因此,矿床成因属于典型的岩浆期后中低温热液型金矿床。In this paper, the geological characteristics and metallogenic controlling factors of the Xinkai gold deposit are analyzed in detail. The results show that the gold-bearing mineralization alteration zone in Xinkai gold deposit is contained in the biotite plagioclase gneiss. In terms of genetics, the mid-acid magma intrusion activity in the Yanshanian period is the dominant factor in the formation of the deposit, which belongs to the medium-low temperature hydrothermal filling type-quartz vein type gold deposit; structure is an important controlling factor for mineralization, controlling the intrusion of magma and the formation and spatial distribution of ore-forming rock bodies and ore bodies. Therefore, the origin of the deposit belongs to a typical post magmatic medium-low temperature hydrothermal gold deposit.
