摘　　要：在详细研究济宁市颜店铁矿区报告和以往资料的基础上,对济宁颜店铁矿部分钻孔济宁岩群的岩矿心进行了编录和系统取样工作,发现济宁岩群存在大量变碎屑岩和首次在钻孔中辨别出碳质岩,这对济宁岩群地层的研究和铁矿成矿作用的研究都提供了重要最新资料。对于铁矿的成因研究和原岩及沉积环境的恢复都有重大的意义。依据岩石组合特征和含矿性,济宁岩群自下而上可划分为翟村组、颜店组和洪福寺组。On the basis of studying previous reports and information of Yandian iron deposit in Jining city,catalog and system sampling of drilling rock cores in Yandian iron deposit in Jining group were carried out.It is found that there was a lot of clastic rock in Jining group,and carbonaceous rocks were distinguished firstly.It will provide important updated information for the study of strata in Jining group and iron ore mineralization.It is important for studying the origin of iron deposit and recovering sedimentary environment.Based on characteristics of rock combination and ore-bearing property,Jining group can be divided into Zhaicun formation,Yandian formation and Hongfusi formation from upper to lower part.
