摘要
河南省煤系沉积型硫铁矿资源较丰富,主要分布于豫中西部和豫北地区的10个矿田范围内。该类型硫铁矿产于石炭纪海侵初期,属泻湖沉积相黄铁矿床,成矿物质为古风化壳和铝土质岩系两种来源。矿层赋存于石炭系本溪组沉积建造底部的铝铁质粘土岩建造中,在氧化带内形成山西式铁矿,原生带保留为硫铁矿。
Coal measures sedimentary type of pyrite resources are abundant in Henan province,which are mainly distributed in 10 ore fields in central and western Henan and northern Henan.This type of pyrite occurs in the early transgression of carboniferous period and belongs to the lagoon sedimentary facies pyrite deposit.The ore-forming materials came from ancient weathering crust and aluminaceous rock series.The ore layer occurs in the aluminum-ferruginous claystone formation at the bottom of the carboniferous Benxi formation sedimentary formation.The Shanxi type iron ore was formed in the oxidation zone,and the primary belt was reserved as pyrite.
