| 摘 要： | 镇康地区位于西南"三江"成矿带南段,是云南省重要的铅锌铁铜多金属矿矿集区之一。区内以铅锌矿为主,次为铁、锡,伴生铜、银;已发现超大型铅锌矿1个,中型铅锌矿3个,小型锡矿1个。文章认为区内的寒武系沙河厂组、核桃坪组及保山组碳酸盐岩地层和奥陶系是本区重要的赋矿层位,铅锌多金属矿床受构造控制明显,多分布在区域褶皱核部断裂带上,往往与夕卡岩型铁矿及夕卡岩体相伴,且产于花岗岩体与围岩接触带上。因此,区内的磁异常及区域低重力场中的次级重力高异常是寻找铅锌多金属矿的主要标志,而铅、锌、铜、银等元素的化探异常及重砂异常范围可指示铅锌矿的存在区域。

| Abstract: | Located in southern section of Sanjiang ore belt in the southwest China, Zhenkang area is one of the important Pb-Zn-Fe-Cu polymetallic deposit-clustered areas in Yunnan Province. In the area, metal deposits are mainly lead and zinc deposits, secondly iron and tin deposits with by-product of copper and silver and 1 super-large and 3 medium Pb-Zn deposits and 1 tin deposit have been discovered. Carbonate rocks of Shahechang formation, Hetaoping formation and Baoshan formation in the Cambrian system and Ordovician system are the important ore horizons in the area. Lead-Zinc polymetallic deposits are controlled by structures evidently and occur in fault zones of regional fold core and are accompanied by skarn iron deposits and skarn rock in the contact zone between granite and the enclosing rock. Magnetic anomaly and secondary gravity high anomly are the prospecting indicator of lead-zinc polymetallic deposits. Geochemical anomaly and heavy mineral anomaly of Pb, Zn, Cu and Ag can imply the existing area of Pb-Zn deposits. |
