一、矿区地貭簡述本区位于淮阳山字型构造的前弧西翼,以折皱构造和挤压性断裂为其特征。区内由志留系-侏罗系地层所构成的折皱和纵向断裂皆呈北西西—南东东向,并且直接控制着区域內各岩浆岩体和有关铁铜矿床的分布。铁山矿区(床)即位于区域内保安复背斜、陈家桥复向斜间之次级构造——铁山背斜的北翼,铁山侵入体的南缘中段。铁山矿区内出露地层以中下三迭统大冶灰岩为主,次为二迭系乐平统硅质页岩层(构成铁山背斜之
First, the mining area 貭 Brief Description This area is located in the Huayangshan font structure of the western front wing, characterized by wrinkle structure and extrusion fracture. The fold and longitudinal faults formed by the Silurian-Jurassic strata in the area show a NW-SE-EAST direction and directly control the distribution of each magmatic rock mass and related iron-copper deposit in the area. The Tieshan Mining Area (bed) is located in the middle of the south anticline of the anticline in the area and the secondary structure of the Chenjiaqiao re-direction between the north flank of the Tieshan anticline and the Tieshan intrusive body. The strata exposed in the Tieshan Mining Area are dominated by the Middle-Lower Triassic Daye limestone, followed by the Permian Leping Siliceous Shale (constituting the Tieshan anticline
