贵州震旦纪沉积碳酸锰矿床呈似层状或透镜状,产于下震旦统南沱冰碛砾岩以下的黑色炭质粘土岩和粉砂质粘土岩岩性段之底部,层位稳定,分布广泛,具有一定的远景意义。对此类矿床的特点及成因,虽有文讨论过,但对其成矿期沉积相的系统研究尚未见有详细报导。笔者就震旦纪锰矿科研工作中所积累的一些实际资料,对沉积相特征和矿床成因作一分析和讨论。
The Sinian sedimentary carbonate-manganese deposit in Guizhou is layered or lenticular in shape and is produced at the bottom of the lithologic segment of black carbonaceous clay and silty clay below the lower moraine conglomerate of the Nonthapo, , Widely distributed, with some long-term significance. Although the characteristics and genesis of these deposits have been discussed in this paper, no systematic study on the sedimentary facies has been reported yet. The author of Sinian manganese ore research work in the accumulation of some of the actual data on the sedimentary facies characteristics and the cause of an analysis and discussion.
