摘　　要：安徽省淮北市双顶山地区水泥原料灰岩矿分布较为广泛,呈条带状延展。矿体呈层状赋存于马家沟组下段(O_(1)m^(1))中,矿体与围岩界线明显,矿床自然类型为厚层状含硅质结核的隐晶质灰岩矿。矿体层位、化学成分较为稳定,矿体与围岩之间的界线呈突变关系,这些特点都是最直接的找矿标志。该地区还具有较好的水泥灰岩矿找矿前景。The cement limestone deposit in shuangdingshan area of Huaibei,Anhui is widely extended in banded distribution.The orebody is bedded in Majiagou Formation Lower Member(O_(1)m^(1)).The boundary between orebody and wall rock is clear.It is the thick bed cryptocrystalline limestone with siliceous concretion.The horizon and chemical composition are stable.The prospecting potentiality of cement limestone deposit is good in this area.
