摘要
河南新县黄岗矿区胡楼铁矿位于东秦岭—大别山成矿带的东段,磁铁矿体均主要产于中新元古界浒湾岩组内的榴辉岩中.区内主要断裂构造为成矿后断裂,且酸性、中性、基性、超基性岩浆岩均有分布.矿石矿物主要为磁铁矿、钛磁铁矿,次为褐铁矿、赤铁矿.围岩蚀变主要有透闪石—阳起石化、绿泥石化、绢云母化.矿体主要受榴辉岩、断裂构造及岩浆岩3个方面控制.
The Hulou iron-deposit of Huanggang in the mine area of Huanggang,Xin County is located in theeastern of Qingling-Dabieshan metallogenic zone.Those orebodies of magnetite are discoveried in the eclogitedistributed in the group of Huwan,Mesoproterozoic.The main structures are fractures after the mineralization andacidic rock,neutral rock,basic and ultrabasic magmatic rocks are distributed in all area.Ore minerals are mainlymagnetite,titanium magnetite,limonite and hematite.The usual alteration types of wall rock comprise tremolite-actinolite petrochemical,chloritization,and sericitization.The ore bodies are mainly controlled by three aspects,including eclogite,fracture structure and magmatic rocks.
