凤凰山铜矿床化探数据研究

The Fractal Study of Geochemical Prospecting Data in South area of Fenghuangshan Copper Deposit

本文通过对凤凰山铜矿床南区不同标高、不同地质体中成矿元素Cu的分形特征的详细研究，确定了本区成矿元素Cu的异常下限为224．274×10^-6.对成矿元素Cu的富集趋势进行了尝试性分析，认为地下较地表、深部较浅部、石英二长闪长岩较花岗闪长岩所经历的成矿期次要多、样品间的差异性要大、成矿元素的富集趋势要强。因此，深部石英二长闪长岩赋存区段是本区最有利的找矿区段。

The fractal character of metallogenic element （Cu） contained in different level and different geological bodies in south area of Fenghuangshan Copper deposit, is analysed and studied in detail.It is ascertained that the low limit of metallogenic element＇ s （Cu） anomalous value is 224.274× 10^-6,and the metallogenic element＇ s （Cu） concentrated trend is ananlysed attemptly. From this,it is presumed that the underground part＇ s,deep part＇ s and quartzite monzodiorite＇ s metallogenic period is more,otherness is-higher,metallogenic element＇ s （Cu） concentrated trend is stronger than the surface part＇ s,superficial part＇ s and granodiorite＇ s.Accordingly, the most favorable mineral prospecting section may be the section consisting of quartzite monzodiorite deeply underground.
