摘　　要：黄羊岭锑矿床是新疆昆仑山腹地新发现的锑矿产地.锑矿产于木孜塔格大型走滑断裂南侧,矿化带受NEE向及EW向次级断裂控制,矿体形态相对复杂,多为似层状、脉状、网脉状、囊状等.岩性组合控矿表现为易于硅化蚀变交代的脆性岩屑砂岩与隔档层页岩构成的岩性圈闭,符合“支撑性岩石与可塑性岩石互层的地层是锑矿成矿最有利的岩性”这一普遍规律.矿床地质和地球化学特征与我国著名的锡矿山锑矿床具相似性.锑矿成矿作用与青藏高原生长和热隆扩展过程中形成的上叠式逆冲、走滑及派生伸展构造有关,推测成矿时代为渐新世.The Huang-yang-lin antimony deposit is newly discovered and is located in the hinterland of the Xinjiang Kunlun Mountains. The antimony deposit occurs on the south side of the major Muzitage sliding fault. The mineralization belt is controlled by secondary faults striking NEE and EW. The goemetry of the ore bodies varies and includes stratum shaped, vein shaped, net shaped and chambered shaped. The deposit is hosted by silicified-altered metasomatic detrital sandstone interlayered with shale. The stratum that is layered by upholding rock and plastic rock is the best host for antimony mineralization. The geology of the deposit and the geochemical characteristics are similar to the famous Hsikuanshan antimony deposit in China. The antimony mineralization is related to inverse up-folding that is thought to have formed during the thermal expansion of the Qinhai-Tibetan highland growth. It is thought that the deposit formed during the Oligocene era.
