在岩心观察的基础上 ,从单井沉积相的分析入手 ,并通过连井对比剖面扩大到全区范围 ,总结了曙一区馆陶组岩石类型和组分、重矿物组成、粒度参数、沉积类型以及沉积构造等方面的特征 ,认为研究区内馆陶组粗碎屑岩属半干旱潮湿环境或是以潮湿气候为主的冲积扇沉积 ,进而总结出馆陶组这种半干旱潮湿环境下冲积扇的微相类型及沉积模式
On the basis of core observation, starting from the analysis of single-well sedimentary facies and extending to the whole area through the continuous well correlation profile, the paper summarizes the rock type and composition, heavy mineral composition, grain size parameter, deposition Type and sedimentary structure. It is considered that the coarse clastic rocks of the Guantao Formation in the study area belong to the semi-arid humid environment or the deposition of the alluvial fan mainly in the humid climate, and then the conclusion is drawn that in the semi-arid humid environment of the Guantao Formation Alluvial fan microfacies types and deposition patterns
