| 摘 要： | 贵州紫云地区上泥盆统代化组以海相碳酸盐岩为主,该组地层发育多套重力流沉积及两套风暴岩的沉积,其中重力流沉积主要以多期块状杂基支撑的砾屑灰岩组成的碎屑流充填为特征,而风暴岩沉积特征主要包括侵蚀构造、洼状交错层理、递变层理及泄水构造等。通过研究发现,本区风暴重力流共发育3种沉积序列组合,这3种序列组合代表了较深水的古地理环境,这就证实了滇黔桂盆地在泥盆纪台地间槽盆环境的存在,其风暴岩的发现指示了研究区晚泥盆世应位于赤道附近的低纬度区域,气候温暖,水体清洁。 |

| Abstract: | The Upper Devonian Daihua Formation in Ziyun,Guizhou is composed mainly of carbonate rocks,in which several sets of gravity flow deposition and two sets of storm deposition were developed.The gravity flow deposition is characterized by debris flow's filling consisting of multi-phase calcarenite with matrix support,whereas the storm sedimentation by erosion structures,sag-like cross-bedding,graded bedding and drainage structure and et al.The research reveals that the gravity flow in this area resulted in thr... |
