【摘要】：正蒙亚啊铅锌矿床位于冈底斯成矿带东段北缘,由西向东与洞中拉、亚贵拉组成蒙亚啊-洞中拉-亚贵拉多金属矿集区。前人对蒙亚啊矿床成因,成岩-成矿年龄以及稳定同位素地球化学特征,主微量、稀土和成矿流体来源等方面做了详细研究。然而对该矿区矽卡岩矿物特征的研究尚有较大不足。因此,本文选取矿床主要矽卡岩矿物作为研究对象,确定矽卡岩矿物类型,剖析矽卡岩矿物空间分带,指导勘查评价,进而为下一步找矿工作提供勘查方向。
[Abstract]:The Zhengmenya Pb-Zn deposit is located in the northern margin of the eastern section of the Gangdis metallogenic belt, from west to east and from the west to the east with the Dongzhongzhonla area, which constitutes the Menga-Dongzhongzhongla polymetallic ore concentration area. Previous studies on the genesis, diagenesis and metallogenic age, stable isotopic geochemical characteristics, main trace amounts, rare earth elements and ore-forming fluid sources of the Mengya ore deposit have been carried out in detail. However, the study of skarn mineral characteristics in this mine is still insufficient. Therefore, this paper selects the main skarn minerals of the deposit as the research object, determines the skarn mineral types, analyzes the spatial zoning of skarn minerals, guides the exploration and evaluation, and then provides the exploration direction for the next prospecting work.
