摘要
文章分析了云南金顶铅锌矿成矿元素特征。对矿区岩石、矿石、矿体等古水文地球化学环境因素对应因子分析认为:矿床是成矿溶液和成矿环境的有机结合体;矿液的性质可通过矿物微量元素特征概略恢复;成矿热液的演化具复杂性和多阶段性;成矿环境差异是矿石、矿体分区分炎的主因,而矿液的来源及性质是不可缺少的条件;成矿流体来自统一的古热储体系,矿物微量元素在含量上有明显差异而组合上无甚差别是热液序列演化的标志。
The paper analyses the ore-forming element characteristics of Pb-Zn deposit in Jinding.From corresponding analysis of the paleohydrogeochemical environment the facfor of rocks, ores andorebodies in ore area, it is concluded that deposit is combined whith mineralizing soution and ore-form-ing environment; the properties of mineralizing solution can be recovered generally by characteristics ofthace elements; the evolution of ore-bearing solution posses complexity and mylti-stages; the differenceof mineralizing environment is the main factors for classing and subdividing the ores and orebodies; thesources and properties of mineralizing solution are pre-conditions; ore-forming fiuid came from thesame system of ancient heat reservoir. The minerals with same trace elements and different content isthe indication of heat solution evolution in order.
