简析新疆哈密大拱梁金矿矿体特征与找矿探讨

To explore the characteristics of Xinjiang Hami gold ore prospecting and analysis of arch

大拱梁矿区金矿位于西伯利亚板块与准噶尔板块的卡拉麦里―塔克扎勒―大黑山晚古生代碰撞带上,出露地层为下石炭统姜巴斯套组地层和华力西中期石英闪长岩等。通过对矿区区域地质和矿区地质进行研究,认识与金矿成矿有关的地层、构造、岩浆岩、围岩蚀变及物化探异常特征,分析矿体特征及矿石特征。对矿床成因进行初步探讨,总结找矿标志,为下一步找矿指明方向。

Gold mine is located in the large arch plate Siberia plate and Junggar Cara Mai Li-Takezhale-Montenegro late Paleozoic collision zone, the exposed strata in the lower Carboniferous jiangbathtao group formation and the middle Variscan quartz diorite etc.. By studying the regional geology and mining geology of the mining area, the authors know the characteristics of the strata and structures related to gold mineralization, Yan Jiangyan, wall rock alteration and geophysical exploration anomalies, and analyze the characteristics of the ore bodies and their ore characteristics. The origin of the deposit is discussed, and the prospecting marks are summarized, which shows the direction for the next prospecting.
