摘　　要：淮北地区分布着大量的中上寒武统灰岩,但同组岩性南北差异较大,南部含镁高,北部含钙高,形成不同矿产。本文基于多年灰岩勘查工作,系统分析南北矿区岩层特征,研究本区岩相古地理环境,总结出形成差异原因。The limestone of the middle and upper Cambrian is widespread in the Huaibei area,but the difference is big between the north and south of the formation,with the south being high in magnesium,and the north high in calcium,thus forming different deposits.Based on years of limestone exploration,this paper systematically analyzes characteristics of the s t r a t a i n the north and south mineral d i s t r i c t s,studies the paleogeographic environment of the area,and summarizes causes of the differences.
