本文在综合部分沉积型工业锰矿床矿物相特征的基础上,试就主要锰碳酸盐的矿物测定、沉积物理化学环境、分带特征的地质应用,谈几点粗浅认识.沉积锰矿床的矿物相特征1.矿石中锰矿物的组成据实验室矿物相分析查定,已知的若干沉积型工业锰矿床中原生沉积含锰矿物有:菱锰矿、钙菱锰矿、锰方解石、含锰方解石、镁菱锰矿、镁钙菱锰矿、镁锰云石、锰云石、铁菱锰矿、含铁菱锰矿、锰铁白云石、锰菱铁矿等.以上表明,矿石中的沉积含锰矿物基本上是由二价锰碳酸盐类矿物组成,且锰、钙、镁、铁普遍具有类质同象替换的特点.
Based on the analysis of the mineralogical characteristics of partial sedimentary industrial manganese deposits, this paper attempts to find out some superficial knowledge about the mineralogical applications of major manganese carbonates, the physical and chemical environment of sedimentary deposits, and the geological applications of zoning characteristics. Phase Characteristics 1. Composition of Manganese Ore According to the laboratory analysis of mineral phases, some of the known sedimentary manganese ore deposits include rhodochrosite, caledonite, manganese calcite, manganese-bearing calcite, Magnesium rhodochrosite, magnesium calcium manganese rhodochrosite, magnesium manganese manganese dolomite, manganese marble, iron rhodochrosite, iron rhodochrosite, manganese iron dolomite, manganite iron ore, etc. The above shows that the ore deposits of manganese-containing minerals basically Is composed of divalent manganese carbonate minerals, and manganese, calcium, magnesium, iron generally has the same phenomenon of isomorphism.
