摘要
东川滥泥坪矿区辉长岩-闪长岩等基性岩浆侵入活动,与铁氧化物型铁铜矿床的形成具有密切的成因关系。在碱性辉长岩-闪长岩岩体边缘分布铁铜金矿(化)体,岩体平均含Cu 0.204%、TFe12.72%、Au 0.099g/t、Ti O23.691%,分别是世界玄武岩的23.1、1.1、20.6、2.1倍,表明岩浆岩体可能为成矿岩体,并与因民组铁铜矿的形成具有直接的因果关系。
Magma intrusion activity of gabbro-diorite rock mass of the Lanniping district of the Dongchuan Copper deposits have consanguineous genetic relationship with the formation of iron-copper deposit of IOCG type deposits.The ore bodies have more iron-mineral where is close to gabbro-diorite rock mass.Gabbro-diorite rock mass have high concentrations of Cu（0.204 %）,Fe（12.72%）,Au（0.099g/t）,TiO2（3.691%）,which implies that the rock mass may be metallogenic rock,and have direct relationship with formation of Copper-iron deposits in Yingming group.
