| 摘 要： | 攀枝花辉长岩体岩浆分异为深源和就地分异并存,可分为两个阶段。原始铁钛氧化物熔浆从下往上分异形成超基性岩—富矿体—辉长岩夹低品级矿石—中品贫矿石—表外矿—辉长岩夹表外矿—辉长岩。依据矿床成因、地质构造、地磁异常特征,认为攀枝花矿尖山矿段深部有望发现大矿。

| Abstract: | The magmatic differentiation of Panzhihua gabbro body is composed of the paragenetic abyssal and on-the-spot differentiation,which can be divided into 2 stages.The differentiation of original Fe-Ti oxide magma forms ultrabasic rock—rich ore body—gabbro with low grade ore—middle grade poor ore—ore outside BS—gabbro with ore outside BS—gabbro from lower to upper.According to the characteristics in genesis of deposit,geological structure,geomagnetic anomaly,we believe that a big ore deposit will be discovered probably in the deep part of Jianshan ore block of Panzhihua ore deposit. |
