摘要
内蒙古毛德班浑迪金矿体赋存于侏罗系上统玛尼吐组安山质岩屑晶屑凝灰岩内,矿体形态呈似层状,赋矿岩性为碎裂状安山质岩屑晶屑凝灰岩,顶、底板围岩均为安山质岩屑晶屑凝灰岩,围岩具硅化、钾长石化、高岭土化、绿泥石化、黄铁矿化等蚀变,矿体受地层和构造控制。本文对矿区地质特征、矿体特征进行研究总结,建立了找矿标志,对该区寻找同类矿床具有较大的实用和借鉴意义。
Maodebanhundi Au deposit of Inner Mongolia occurs in the andesitic lithic-crystal tuff of Manitu Formation of Upper Jurassic system,and the orebodies occur as stratoid in form.The host rock is cataclastic andesitic lithic-crystal tuff,and wall rocks of roof and floor are andesitic lithic-crystal tuff.The wall rocks are characterized by alteration,such as silicification,potassium feldspathization,kaolinization,chloritiza-tion,and pyritization,and the orebodies are controlled by strata and structure.This paper studied and sum-marized geological characteristics of the mining area and features of orebodies,and defined clues for prospec-ting,which would have practical and reference significance in searching for similar type deposits.
