摘要
内蒙古拜仁达坝-维拉斯托矿床是大兴安岭中南段西坡成矿带的重要组成部分,从大地构造上来说属于中亚造山带东部。在此地区先后发现了拜仁达坝银铅锌多金属矿床以及维拉斯托银铅锌多金属矿,而近期发现的维拉斯托锡-钨-铷矿床无疑为此地区矿床成矿模式研究增加了依据。在总结前人在构造特征、矿石特征及成矿流体特征研究成果的基础上,运用幔枝理论对本地区成矿模式进行探讨。研究表明拜仁达坝-维拉斯托矿床为幔枝构造成因矿床,包含一个斑岩型矿床以及两个浅成热液型矿床,矿床经历了多期次矿化,初始成矿深度为1-3公里。
The Bayern Dam-Velasto deposit in Inner Mongolia is an important component of the western slope of the Daxing＇anling,which belongs to the eastern part of the Central Asian orogenic belt from the tectonic structure.People in this area has discovered the Bayern Daba silver-lead-zinc polymetallic deposit and the Velasto silver-lead-zinc polymetallic ore.Recently the discovered Vilasto-tungsten-rubidium deposit is undoubtedly increasing information of mineralization model of this area.Based on the research results of structural features,ore characteristics and ore-forming fluid characteristics,this paper discusses the metallogenic model of the region by using the theory of mantle.The study shows that the Bayern DamVelasto deposit is a mantle-tectonic deposit,and the Bayern Dam-Velasto deposit consists of a porphyry deposit and two superficial hydrothermal deposits.The deposits experienced a multi-mineralization,the initial mineralization depth is 1-3 km.
