我国某地区铁铜矿床中伴生元素的分布与赋存特征

THE CHARACTERISTICS OF THE DISTRIBUTION AND OCCURRENCE OF THE ASSOCIATED ELEMENTS IN SOME IRON-COPPER ORE DEPOSITS IN A CERTAIN DISTRICT, CHINA

Any of iron-copper ore deposits, without exception, contains various associated components. The studies on the distribution and mode of occurrence of over 20 associated elements in 87 iron-copper ore deposits in a certain district in China have shown that the specificity of the associated element distribution is eontrolled by the type of the deposits, that there exists a close relation between ore.forming and associated elements, and that the formation conditions and type of ore deposits, and the geochemical properties of the elements are the decisive factors governing the migration and enrichment of the associated elements during minerogenetie process.
