摘要
赵平房矿区位于辽河平原东部,地形平坦,属海积平原。矿床赋存于第四系土层之下,产于太古界鞍山群茨沟组含角闪磁铁石英岩中,属鞍山式铁矿。本文详细地介绍了矿床的地质特征,分析了矿床成因:原岩为海相拉斑玄武岩-硅铁沉积建造;属火山沉积—变质改造型矿床。提出了找矿标志,为找矿指明了方向。
Zhaopingfang mining area is located in eastern part of Liaohe smooth plain,which belongs to marine –deposition plain.The deposit occurs in under the Quaternary sola,Formed in hornblende magnetite quartzite of Cigou Formation,Anshan Group of the Archaeozoic erathem,which belongs to Anshan type iron deposit.The paper introduced in detail geological features of the ore deposit,genesis.The protolith shows marine tholeiite-fersilicite sedimentary structure,which belongs to volcanic sedimentary-metamorphic reformation deposit,meanwhile,the paper proposed ore –prospecting criteria for further ore –prospecting in the study area.
