中文摘要:
      为探究河南陈楼萤石矿床M3-I矿体原生晕特征及深部成矿潜力,对矿体189件样品测试数据进行分析研究。结果表明,M3-I矿体有效的原生晕指示元素组合为F、Ca、Y、Ag、As、Sb、Mo、Ba、Ce;矿体原生晕轴向分带序列为Mo-Sb-Ca-F-Ag-Ce-As-Ba-Y,具明显的“反向分带”特征,矿体剥蚀系数具振动波状变化趋势,矿体向深部有较大延伸或存在盲矿体。文章建立了矿体原生晕叠加理想模型,在484 m中段至364 m中段存在一个矿体B的头部叠加在矿体A的下部,矿体B在334 m中段以下仍有较大延伸。
英文摘要:
      In order to explore the primary halo characteristics and deep metallogenic potential of M3-I orebody in Chenlou fluorite deposit, 189 samples from five middle sections of the ore body were analyzed. The results show that the effective primary halo indicator elements of M3-I orebody are F、Ca、Y、Ag、As、Sb、Mo、Ba、Ce. The axial zoning sequence of the primary halo of the ore body is Mo-Sb-Ca-F-Ag-Ce-As-Ba-Y, which has the obvious "reverse zoning" feature, and the orebody denudation coefficient shows the trend of decreasing from small to large, both indicate that the orebody has experienced multi-stage mineralization and the orebody extends to the deep or there is blind orebody. Based on the field investigation of the ore body, an ideal model of primary halo superposition of M3-I ore body is established. It is considered that there is a head of ore body B superimposed on the lower part of the strongly denuded orebody A in the middle part of 484m to 364m, and the ore body B still has a large extension below the middle part of 334m.
