攀枝花阿喇地区晶质石墨矿地质特征及找矿前景

Geological Features and Prospecting Perspective of the Ala Crystalline Graphite Deposit in Panzhihua

四川省攀枝花市阿喇地区位于康滇地轴中段西缘,大田背斜南翼,石墨矿产于前震旦系康定群咱里组地层中。矿床属于区域变质型石墨矿床,矿体严格受层位的控制,石墨为片麻岩型及片岩型。通过区内成矿地质特征及地球物理特征对比分析,类比区内典型石墨矿床,认为阿喇地区石墨矿成矿受地层、构造、岩浆岩、变质作用、混合岩化等因素影响。经综合分析,认为阿喇地区石墨矿找矿前景较好。

The Ala crystalline graphite deposit in Panzhihua lies in the southern limb of the Datian anticline on the western margin of the Kangdian axis and occurs in the Zanli Formation of the Pre-Sinian Kangding Group.The deposit belongs to metamorphic one,including schist type ore and gneiss type ore.The graphite orebodies are controlled by stratigraphic horizon,structure,magmatism and metamorphism.Geological and geophysical features of the deposit show its good prospecting perspective.
