内蒙古阿吉勒银铅锌多金属矿床控矿条件及找矿方向分析

摘要

The perspective Ajile silver-Lead-Zinc polymetallic deposit has been put forward to the study area lately , located in north part of the north China plate and Siberia plate suture zone , about 110km from the Arhada Lead Zinc deposit .The lead-zinc ore occurs mainly in volcaniclastic rock of Caboniferous-Permian.Ore-bearing layers offered metal source .The de-posit was structurally controlled by north-west fracture structure and the structure offered dynamic force for ore forming , which made the ore-forming source activated , transferred and deposited in favorable location .Through analysis of major ore controlling factors , further prospecting direction is indicated .%阿吉勒银铅锌多金属矿为新近发现的有找矿前景的一处普查区。矿区位于华北板块与西伯利亚板块缝合带的北侧。距阿尔哈达铅锌矿110 km。铅锌矿脉主要赋存于石炭系-二叠系火山碎屑岩中，该地层提供了矿源层；受NW向断裂构造控制，构造提供了矿化进一步富集的动力条件，使矿质得以活化、迁移并在有利成矿空间定位形成矿体。本文通过对控矿因素进行了分析，指明了下步找矿方向。
