摘　　要：黑龙江省大兴安岭新林区460高地钼铜多金属矿床位于北东向塔源—兴华岩石圈断裂构造南东侧,近年来在该区陆续发现了岔路口、小柯勒河、大黑山等大、中型斑岩钼(铜)矿床,逐渐成为一个以钼为主的多金属矿集区。文章通过对460高地钼铜多金属矿床的地质特征、矿体特征及地球物理、地球化学特征的分析,提出该矿床具有典型斑岩矿床特征,已发现的钼、铜矿体多处于石英–绢云母–强黄铁矿化带之上。推测矿区的西部外侧(136勘探线与534高地之间)及深部是成矿斑岩赋存部位,斑岩顶部及边部是寻找到厚大的、高品位矿体的理想场所。The 460 highland Mo-Cu polymetallic deposit in Xinlin district of Heilongjiang is located in the southeast of the Tayuan-Xinghua lithosphere fault structure.In recent years,large and medium-sized porphyry Mo(Co)deposits have been discovered in the area,such as Chalukou,Xiaokelehe and Daheishan.The belt gradually became a polymetallic ore concentration area dominated by Mo.Based on the analysis of the geological features,ore body features,geophysics and geochemistry features of the 460 highland Mo-Cu polymetallic deposit in Xinlin district,this paper is pointed out that the deposit has the typical characteristics of porphyry,and the Mo and Cu ore bodies which had be discovered are mostly located on the quartz-sericite-strong pyrite zone.It is speculated that the ore-forming porphyry is located in western outer(between the 136 exploration line and 534 Highland)and deep part of the mining area.It is an ideal place for finding thick and high grade ore bodies at the top and sides of porphyry.
