| 摘 要： | 金石坡Zn、Cu矿床位于著名的滇东南都龙环形旋扭构造西南侧,属都龙矽卡岩型锡石多金属矿田部份,矿质来源于老君山燕山早期的花岗岩基。文章通过对金石坡矿区大量探采工程及周边矿区资料的综合研究,深入剖析了构造、岩性,围岩圈闭条件对矿床规模大小、富集程度的制约;探讨了南北矿带中矿床沿平、剖面的总体展布规律与控矿特征;提出了金石坡锌铜矿床三位一体控矿组合,其中尤以层间滑动带通过碳酸盐岩不同岩石界面为最佳;在此基础上,重点指出了南北矿带中同类型矿床寻找的有利部位,同时对整个环形旋扭构造不同区域、不同矿种的构造控矿特征作了有益的探讨、预测。

| Abstract: | Jinshipo Zinc-Copper deposit,situated to the southwest of the knob-ring structure of Mount.Dulong in southeastern Yunnan Province,is part of Dulong Skarn-type cassiterite-polymetallic ore field and born from the early Laojunshan Yanshan-period-formed granite base.Through a comprehensive study of a large number of engineering projects in and around Jinshipo deposit,this paper presents an in-depth analysis of the constraints of structure,lithology and rock trap conditions upon the ore's size and enrichment;pr... |
