四川凉山平川铁矿致矿侵入体与大板山岩体的关系

平川矿山梁子铁矿矿区内的苦橄玢岩被认为是该铁矿的致矿侵入体,但其形成原因并未有前人进行过研究。大板山岩体作为一个规模较大的镁铁-超镁铁质岩体,通常被前人用作铜-镍硫化物矿床的研究,并未与铁矿床进行过成因联系。本文选择平川铁矿的致矿侵入体及大板山基性-超基性岩体为研究对象,探讨两者的时空结构及其岩石矿物关系,为平川矿山梁子铁矿提供新的成矿模式。

The relationship between causing intrusions and Dabanshan mass of rock of the Pingchuan iron deposit in the Liangshan prefecture, Sichuan province

The picritic porphyry is regarded as the causing intrusion in the Pingchuan iron deposit, kuangshanliangzi ore district. However, the cause has not been studied by the researchers. Dabanshan mass of rock is a mafic and ultramafic rocks which has a large-scale, which is also a good subject of researching Cu-Ni sulfide deposit, but it is not applied to iron deposit by the researchers. We choose the causing intrusions of the Pingchuan iron deposit and Dabanshan mass of rock as the researching subject,and study the space-time structure and rock-mineral relations. It can be a good genetic model for exploring in the kuangshanliangzi ore district of Pingchuan iron deposit.
