内蒙古额济纳旗白山铁矿成矿地质特征与成因分析

Metallogenic geological characteristics and genetic analysis of Baishan Iron Deposit in Ejinaqi,Inner Mongolia

白山铁矿属于典型的岩体控矿,磁铁矿体赋存于晚石炭世基性侵入岩体中,区内褶皱、断裂发育,岩浆活动较强,岩浆沿着断层运移或在虚脱部位岩体侵位以及在一些与大断层伴生多级小断裂的某些部位极易聚积成矿[1],本文从区域地质背景、矿区地质特征及矿体地质特征分析白山铁矿成矿地质条件及矿床成因。通过分析矿区岩浆岩、脉岩、断层、褶皱的产状及产出特征和变化情况,以期对矿区后续的找矿工作做出理论上的指导。

The Baishan iron deposit is a typical ore-controlling rock body.The magnetite body occurs in the basic basic intrusive rock body of the late carboniferous.The folds and faults are well developed in the area,and the magmatic activity is strong,the magmas migrated along faults or emplaced in the collapsed part of the rock mass and easily accumulated in some parts of some minor faults associated with large faults[1],geological characteristics of ore area and orebody analysis of ore-forming geological conditions and Genesis of iron deposit in Baishan.The occurrence,characteristics and changes of magmatic rocks,dikes,faults and folds in the mining area are analyzed in order to provide theoretical guidance for the future prospecting work.
