玲珑金矿田矿物组合与地球化学分带及矿体定位预测意义
SIGNIFICANCE OF MINERAL ASSEMBLAGE AND GEOCHEMICAL ZONING ON THE OREBODIES PROSPECTING IN LINGLONG GOLD OREFELID
【摘要】 详细讨论了玲珑金矿田矿物组合和元素的空间分带 ,二者之间的一致性说明矿物组合的空间分带是宏观的元素地球化学分带 ,且具有远程有序和短程无序的特点。同时在矿田水平方向上 ,由SE→NW金属矿物的种类和含量呈增加的趋势 ,由少硫化物蚀变岩型向多金属硫化物石英脉型变化。由于不同矿物组合的矿脉赋矿标高具有较大的差异 ,这为矿体的定位预测提供了矿物学依据 ;另外矿物组合的垂向分带 ,对判定矿体的剥蚀深度和延深也具有重要的参考价值
【Abstract】 Mineral assemblage and geochemical space zoning in Linglong gold orefield are discussed in the paper. The consistency of each other showed mineral assemblage zoning is indication of geochemical space zoning, and the zoning is characterized by order in long distance and disorder in shorter distance. The species and abundance of metal minerals increasing from SE to NW in horizon, corresponding transformation from sulfide altering orebody type to quartz vein orebody type. Due to the different height at which orebodies occurred with different mineral assemblage, the orebodies can be prospected by this rule. Additionally, it can be used to definite the extension of orebodies.
【Key words】 Linglong gold orefield; mineral assemblage; space zoning; orebody prospecting;
