在云南省罗茨—武定地区西矿带中元古界昆阳群大箐亚式含铜白云岩中有碳酸盐浆屑和熔融包裹体存在。熔融包裹体可以分为碳酸盐的和硅酸盐的两类。其中硅酸盐的平均化学成分相当于粗面质和粗安质碱性岩浆成分。该发现证明本区中元古代确有硅酸盐—碳酸盐混合岩浆活动，大箐含铜白云岩很可能与此有关
Carbonate pulp and melt inclusions are present in the Jurassic Au-bearing dolomites of the Middle Proterozoic Kunlun Group in the western ore belt of the Roots-Wuding area in Yunnan Province. Melt inclusions can be divided into two types of carbonate and silicate. The average chemical composition of silicate which is equivalent to rough and rough alkali alkaline magmatic composition. This finding proves that Mesoproterozoic metasomatic silicate-carbonate magmatic activity in this area is likely to be related to the Cu-bearing dolomite
