内蒙古阿拉善地区两类孔雀石化的形成机理初步分析

Initial Mechanism Analysis of the Malachite Mineralization in the Alxa Area,Inner Mongolia

阿拉善地区存在两种成因类型的孔雀石化,Ⅰ类型孔雀石化是铜矿化(铜矿体)氧化形成的,是良好的找矿标志;Ⅱ类型孔雀石化是在阿拉善地区特殊的气候条件下形成的,不具有找矿意义。正确区分和鉴别上述两种成因类型的孔雀石化,对于正确指导找矿,具有十分重要的理论和实际意义。

There are two genetic types of the malachite mineralization in Alxa area, one kind of the malachite mineralization is due to oxidation of the cu-mineralization, which is a favorable criteria for ore prospecting. The other kind of the malachite mineralization is due to the particular climatic condition of Alxa area, which is not a criteria for mineral prospecting. To distinguish and identify the two genetic types of the malachite mineralization is important for correct mineral prospecting, both theoretically and practically.
