阿斯道恰含矿花岗伟晶岩铍矿床,赋存于黑云母-石英片岩的接触带中。矿脉受围岩裂隙控制,形态不规则,地表呈脉状展布。矿区内共圈定了55条伟晶岩脉,伟晶岩脉分布广,数量多,呈密集产出。走向为310°~320°,倾向北东,倾角55°~60°。都是岩浆岩的分异期后的派生热液,沿片麻岩及花岗岩的片麻理及节理裂隙贯入而形成。现矿区范围内可供开采的仅有1号伟晶岩脉。通过对矿区成矿地质特征的总结及成矿地质条件分析研究,评价矿区的成矿潜力,指出进一步找矿的方向。
Aspidolite ore-bearing granitic pegmatite beryllium deposits, occurring in the contact zone of biotite-quartzite schist. The veins are controlled by the fractures of the surrounding rock, with irregular shapes and veins spreading on the surface. A total of 55 pegmatite veins were delineated in the mining area. Pegmatite veins are widely distributed and in large numbers with intensive output. Towards 310 ° ~ 320 °, the northeast tend to tilt 55 ° ~ 60 °. All of them are derived hydrothermal fluids after the differentiation of magmatic rocks. They are formed along the gneissic and jointed fissures of gneiss and granite. Now available for mining within the scope of the No. 1 pegmatite. Through the summary of mineralization geological characteristics and the analysis of metallogenic geological conditions, the ore potential of the mine area is evaluated, and the direction of further ore prospecting is pointed out.
