【摘要】 大铜厂铜矿床为陆相沉积砂砾岩型铜矿床。矿床与盆地内下部含煤建造、中部红色含铜碎屑岩建造和上部白色膏盐建造关系密切。含矿岩系具有向上变细的剖面结构。矿体严格受白垩系地层控制并呈层状似层状产出。含矿岩石以细砾岩为主,铜矿化与沉积物颜色、砾岩中砾石成分亦有着密切关系。更多还原

【Abstract】 The Datongchang copper deposit is a continental sedimentary glutenite type copper deposit.It is closely related with the lower coaly formation,the middle cupriferous formation and upper gypsum-salt formation.The grain size of the ore-bearing formations become finer upward in the cross section.The ore bodies are strictly controlled by the cretaceous strata and occur as stratified.Cupriferous rocks are mainly fine conglomerate,mineralization is also closely associated with the sediment color and the gravel composition in the conglomerate.更多还原
