| 摘 要： | 阿希金矿床赋存于下石炭统大哈拉军山组陆相火山岩中,成矿与破火山口(火山机构)环状断裂构造系统有关,属典型的冰长石-绢云母型大型金矿.阿希金矿近矿围岩蚀变为硅化、绢云母化、冰长石化、叶腊石化、绿泥石化等,以主矿体为中心向两侧共划分出6个蚀变矿物组合带,其中强硅化带和绢英岩化带与金矿化关系密切.

| Abstract: | Axi gold deposit, which is occurred in the continental volcanic rocks of Lower Carboniferous Dahalajunshan formation, belongs to typical large gold deposit of adular-sericite type. The mineralization is related to the ring fracture system in the caldera rim(volcanic apparatus). The near-ore wall-rock alteration of the deposit contains mainly silicification, sericitization, adularization, pyrophylitization, chloritization etc. From the main orebody to both sides, the alteration can be zoned into six mineral assemblage zones, i.e., 1)strong silicification zone(auriferous quartz), 2)symmetrical phyllic alteration zone, 3)sericitization zone, 4)propylitization zone, 5)weak sericitization zone and 6)weak propylitization zone, of which the strong silicification and phyllic alteration zones are closely related to gold mineralization. |
