在辽宁下兰家沟钼矿床及其周围相类似的矿化显示中,普遍发育以菱锰矿、方解石为主要组分的碳酸盐化.这些碳酸盐矿物与钼矿体在空间分布上有广泛的一致性,在地表露头又常形成很特征的黑色氧化锰薄膜,因此可以作为隐伏钼矿体的找矿标志.本文通过对各种产状的碳酸盐矿物样品进行显微镜观察、差热分析、热重分析、X射线粉晶衍射分析、原子吸收光谱分析、化学分析、氧碳同位素分析,以及包裹体测温等,初步查清了各种产状的碳酸盐组分特征及其可能来
In the similar mineralization of the Langjiagou molybdenum deposit and its surroundings in Liaoning Province, the widespread occurrence of carbonation with rhodochrosite and calcite as the major constituents shows the spatial distribution of these carbonate minerals and molybdenum ore bodies A wide range of consistency in the surface outburst and often form a very characteristic black manganese oxide film, so it can be used as a prospecting symbol of the buried molybdenum ore body.Through the microscopic observation of carbonate minerals samples of various origin, differential heat Analysis, thermogravimetric analysis, X-ray powder diffraction analysis, atomic absorption spectroscopy, chemical analysis, oxygen and carbon isotope analysis, as well as temperature measurement of inclusions, initially identified the characteristics of carbonate species and their May come
