| 摘 要： | 中国地质调查局天津地质调查中心与黑龙江省地质调查研究总院齐齐哈尔分院合作,在内蒙古霍林郭勒地区发现昌图锡力锰、银、铅、锌多金属矿床。矿床所在大地构造位置为中亚造山带东段,矿床产于中生代白音高老组中发育的北西向破碎蚀变带中。经地表槽探揭露可见7条矿脉沿北西向平行展布。矿体及围岩中仅发现低温蚀变,主要包括硅化、绢云母化、绿泥石化、褐铁矿化及碳酸盐化。根据蚀变矿物类型及矿体强烈受北西向构造控制等特征,初步判断矿床可能为浅成低温热液矿床。在大兴安岭中南段首次发现锰多金属热液矿床,暗示在太平洋构造域控制下,大兴安岭中南段北东向成矿带内部可能存在受北西向构造控制的次级成矿带。

| Abstract: | A Mn, Ag, Pb, Zn polymetallic deposit was discovered in Huolingol area of Inner Mongolia by Tianjin Center of China Geo-logical Survey together with Qiqihar Branch of Heilongjiang Institute of Geological Survey and Research. The tectonic position of the deposit is in the eastern part of the Central Asian Orogenic Belt. The deposit was formed by NW-striking cataclastic alteration in Baiyin-gaolao Formation. Seven parallel NW-striking ore veins are exposed by trenching. There are many kinds of low-temperature hydro-thermal alteration in the orebody and wall rock, such as silicification, sericitization, chloritization, limonitization and carbonation. The deposit is probably an epithermal deposit, as shown by different kinds of alteration and the features of controlling role of the NW-strik-ing structure. There probably exists a secondary metallogenic belt which is controlled by the NW-striking structure in the northeast metallogenic belt that is controlled by Pacific tectonic domain in the middle-southern segment of the Da Hinggan Mountains. |
