| 摘 要： | 河北平泉地区冶里组碳酸盐岩风暴沉积极为发育,含原地型风暴岩、异地型风暴岩、风暴浊积岩和生物截丘灰岩等4种类型.风暴沉积反映本区冶里组沉积时经历了一个完整的海进-海退旋回,当时区内古地理面貌为北高南低、海水北浅南深.此外,风暴沉积在露头层序地层划分中,对于海进体系域和高水位体系域的识别具有重要的指示作用.

| Abstract: | The carbonate storm deposit (tempestite) of early Ordovician Yeli Formation is well-developed in Pingquan area, Hebei Province. Four types of tempestite, which is autochthonous coarse grain limestone, allochthonous coarse grain limestone, turbidite and cutting bioherm limestone, are found. On the studying of storm deposit, it is determined that the Yeli Formation is made up of a whole ingression to regression succession, and the topography is higher in north and lower in south, the sea water is shallow in north and deep in south. Besides, the storm deposit is a important indication for identifying the transgressive systems tract and highstand systems tract in outcrop sequence stratigraphy dividing. |
