前人对本区的矿床成因类型曾做过若干工作,有人认为是“矽卡岩型”铁矿,也有人认为是“高中温热液”矿床.鞍钢四○三队,对该区已知铁矿及其外围进行了找矿和矿点评价工作,相继发现了含钴黄铁矿和铜矿,初步查明是一个以铁、铜、钴为主的多金属成矿带.此矿化带赋存于前震旦系变质火山岩系中,矿床的形成与喷气-沉积作用及混合岩化后期热液改造有关.区域地质地层主要为前震旦系鞍山群和辽河群古老变质岩系.岩系及厚度变化明显,主要
Some people have done some work on the genesis type of the deposit in this area, some people think it is “skarn-type” iron ore, and some people think it is “High School Hydrothermal Fluid” deposit. It is known that iron ore and its periphery have been used for ore prospecting and ore deposit evaluation. Cobalt-bearing pyrite and copper ore have been discovered one after another, and it is initially identified as a polymetallic metallogenic belt dominated by iron, copper and cobalt. This mineralization zone occurs in the former Sinian metamorphic volcanic series, and the formation of the deposit is related to the jet-sedimentation and hydrothermal alteration in the late stage of mixed lithification.The regional geological strata are mainly composed of the former Sinian Anshan Group and the Liaohe Group, the ancient metamorphic rocks The rock series and thickness have obvious changes, mainly
