摘　　要：桃花山水泥用灰岩矿矿床位于枣庄市峄城城区,赋存于寒武纪九龙群张夏组地层中,呈层状产出,共分2个矿层,含5个夹石层。矿区分东、西2个矿段,西矿段矿石质量较好,无夹层;东矿段局部存在高镁、高碱夹石层。矿床平均有益、有害组分为Ca O 52.75%,Mg O 1.70%,R2O 0.269%,矿床属海相沉积矿床。Taohuashan limestone for cement deposit locates in Yicheng district of Zaozhuang city. It occurs in Zhangxia formation of Cambrian Jiulong group and shows layered type. It is divided into two strata,and including five middle ages bands. Mining areas can be divided into east and west part. Ore quality in west part is good without interlayer; while high magnesium and high alkali interlayers occurred in east part. Beneficial and harmful components are as follows： the average rate of Ca O is 52. 75%; the average rate of Mg O is 1. 70%,and the average rate of R2 Ois 0.269%. This deposit belongs to marine facies sedimentary deposit.
