摘要
In recent years, mixed sedimentation of terrigenous clast and marine carbonate is found in Xiangyangsi Formation of Devonian in Shidian area, it represents the mixed sequence of terrigenous clast and carbonate, terrigenous clast and diamictite, carbonate and diamictite, diamictite on the view of macroscopic. On the view of microscopic, it represnets the diamictite formed of terrigenous clasfic component and carbonate component in the same stratum. The study will be helpful for remaking the paleoelimate and sedimentary environment of this area, therefore it has very important geologic significance.
