摘要
吴庄铁矿是目前在采的中型规模矿山,为扩大矿山后备资源,通过分析其地质特征及控矿条件,为今后的找矿方向提供指导。研究认为:吴庄铁矿由主矿体和小矿体组成,主要为磁铁矿石、赤铁矿—磁铁矿石和少量赤铁矿石,围岩蚀变以绿泥石化和碳酸盐化为主。矿体严格受利国岩体与奥陶系碳酸盐岩接触带的控制,主要赋存于岩体上隆部位的接触带及其附近裂隙中,成矿方式包括交代和充填方式,矿床成因类型属接触交代—高、中温热液充填型矿床。今后找矿方向应以寻找岩体与奥陶系接触带为目标,其东南部的深部接触带是找矿的重点,矿区西部也是有利的找矿部位。
Wuzhuang Iron Mine is a medium-sized mine currently under mining.In order to expand the reserve resources of the mine,the geological characteristics and ore-controlling conditions are analyzed which provides guidance for the future prospecting direction.The study shows that Wuzhuang iron ore is composed of main ore body and small ore body,mainly magnetite,hematite-magnetite and a small amount of hematite.The wall rock alteration is mainly chlorite and carbonate.The ore body is strictly controlled by the contact zone between the Liguo rock mass and the Ordovician carbonate rock,and mainly occurs in the contact zone at the uplift part of the rock mass and its adjacent fractures.The metallogenic methods include metasomatic and filling methods.The genetic type of the deposit belongs to the contact metasomatic-high and medium-temperature hydrothermal filling deposit.The prospecting direction in the future should be to find the contact zone between the rock mass and the Ordovician,and the deep contact zone in the southeast is the focus of prospecting,the western part of the mining area is also a favorable prospecting site.
