东川滥泥坪铁铜矿体形态特征与控矿因素

The Morphological Characteristics of Iron-Copper Orebody and Ore-Controlling Factors in Lanniping,Dongchuan

采用不同中段坑道对比方法对东川滥泥坪矿区深部不同标高中段进行对比,阐述了滥泥坪矿区铁铜矿体的形态特征和控矿因素。认为滥泥坪铜矿区铁铜矿体主要受地层、构造(褶皱和断裂)和岩浆岩控制,铁铜矿体呈透镜状、脉状和似层状产出,矿体产状较稳定,矿体厚度和品位变化较大。

Using different middle tunnel comparison method, to comparative study the different elevation of middle in the deep of Lanniping mining area, Dongehuan, expatiate the morphological characteristics of the Lanniping iron-copper orebody and ore-controlling factors. Studies suggest that Lanniping copper area of iron-copper orebody is mainly affected by the formation, structure（folds and faults） and magmatic rocks control, iron-copper ore bodies take the shape of lentieular, vein, layered distribution, orebody attitude is more stable, the orebody of thickness and grade change greatly.
