摘要
通过对天津蓟县雾迷山组典型凝块石露头的组构特征研究,将凝块石白云岩划分为两大类型,六个亚类。结合凝块石白云岩的沉积和相序结构研究表明其为中元古代潮坪沉积形成。此外,也确定了构成储层的岩石类型和储集空间类型。
Based on the texture and structural features of typical outcrops of clot in Wumishan Formation in Jixian County,Tianjin,China.Clotted dolomite can be divided into two types and six subtypes.In combination with a study on the sedimentation and facies succession structure of the clotted dolomite,we determined that the Mesoproterozoic period accepted tidal clotted dolomite deposition,in addition,we determined that main reservoir rock and storage space types.
