云南钴矿地质特征及找矿探讨

云南钴矿化类型较为多样 ,多产铜、铜镍、铂钯及铁矿床中 ,尤其是东川式铜深部条件与胡篦型深部店头铜矿发现富钴矿脉极类似 ;新平大红山铁矿下部铜矿含钴又与海南石录铁矿下部含钴铜矿(大型 )甚为相似。在沉积改造型铅锌矿下部 (螺丝塘 )发现富钴矿脉 ,是重要的找矿新线索。从铜矿床的伴 (共 )生钴入手 ,并深入研究大红山含钴铜矿及螺丝塘铅锌矿下部的富钴矿化 ,是云南扩大找钴的重要方向。

GEOLOGICAL CHARACTERISTICS OF COBALT RESOURCES IN YUNNAN AND ITS EXPLORING GUIDE

Cobalt mineralization in Yunnan is relatively type-diversified, probably taking place in copper, copper-nickel, platinum, palladium and iron deposits, especially at the deep parts of the Dongchuan-type and Hubi-type copper deposits. The same case is with Xinping Dayishan and Hainan Shilu copper deposits. Besides, lower parts of some sedimentary and reworked lead-zinc deposits (Luositang deposit for exsample) are also proven to host cobalt-rich veins. All this will become a guide to hunting cobalt resources. Concretely speaking, having in mind the prominent characteristics of cobalt often associated with copper or lead-zinc deposits and lucubrating the deep cobalt mineralization of Dayishan copper deposit and Luositang lead-zinc deposit will be an important direction to vigorously prospecting for cobalt deposits in Yunnan province.
