磁海式铁矿是我国近年来勘探成功的一种富铁矿类型.以其出现在华力西地槽晚期旋回、靠近古陆边缘的火山断陷沉积盆地中,成矿与二迭纪玄武质火山-基性岩浆的深部分异和岩浆期后气液演化密切相关,矿体主要赋存在辉绿岩中,具有独特的成矿特征,故名之.这类铁矿在国内系初次发现,与国外已知产于暗色岩或辉绿岩中的铁矿亦有所不
Magnetic sea iron ore is a kind of rich iron ore successfully explored in recent years in our country.With its appearance in the late Varys Trough, which was close to the volcanic faulted sedimentary basin at the edge of the ancient land, The deep differentiation of the mass volcano-basic magma is closely related to the evolution of gas and liquid after the magmatic period. The ore body is mainly located in the diabase and has a unique mineralization feature named after it , But also with iron ore known to be produced in dark-colored rocks or diabase in foreign countries
