摘要
内蒙古阿拉善盟西北部普遍出露古元古界北山岩群海相变质火山-沉积岩系,泥盆纪-志留纪花岗质侵入岩发育,在岩体与北山岩群的外接触带发育矽卡岩化带,部分地段形成磁铁矿及黄铜矿.以标山南东磁铁矿点为例,对该地区磁铁矿的成矿地质条件、成因及找矿标志进行分析总结,对北山地区地质找矿工作具有一定启发意义.
Abstract
Metamorphosed volcanic-sedimentary rock series of marine phase of Paleoproterozoic Beishanyan group are extensively exposed in the northwest of Alashanmeng in Inner Mongolia.Devonian-Silurian gra-nitic pluton is abundant.The Skarn zone is developed in the outer contact zone of pluton and Beishanyan group.Magnetite and chalcopyrite are formed in the part of the section.The paper has analyzed and summa-rized the metallogenic geological condition,genesis and magnetite prospecting symbol in this area by taking the magnetite occurrence in the southeast of Biaoshan as an example.
