graded bedding

Open platform facies metamorphic rocks are massive micritic bioclastic limestone and bioclastic limestone, with massive bedding, convolute bedding and graded bedding biological debris.

开阔台地相岩石类型主要为块状泥晶生屑灰岩和生屑灰岩，具块状层理、丘状层理和生物屑粒序层理。

Distinct causes of formation for different graded bedding in debris flow deposits have been analyzed using the ratio of flow plug.

应用层理结构的分类指标&流核比，对泥石流堆积层理的正粒序、反粒序和混杂粒序等进行成因差异分析。

Compared with the normal tidal flat sedimentation, the storm sedimentation has the characteristics of coarse particle, bad sorting, relatively high roundness, obviously graded bedding, typical parallel bedding, cross bedding.

该带的风暴沉积与正常的潮滩沉积比较，具有粒度较粗，分选较差，磨圆稍好，递变现象明显，平行层理或波状交错层理发育比较典型的特征。

Depositional beddings such as graded bedding, massive bedding, parallel bedding, cross-bedding and wave bedding, are well developed;

粒序层理、块状层理、平行层理、交错层理、波状层理十分发育；

The latter consisting of dark gray clastic limestone, chert beds, siliceous mudstone and massive reef and usually with graded bedding.

石灰岩建造常为黑色、灰黑色碎屑石灰岩、燧石层、粉砂质泥板岩和礁灰岩组成，常夹递变层理。

Analyzing Study on Graded Bedding Texture in Debris Flow Deposits

泥石流堆积层理结构的分析研究

The first member of Daye limestone yields hummocky ripple marks, hummocky cross bedding and graded bedding, which are the reflection of storm process.

其第一段岩石发育了丘状波痕、丘状交错层理及粒序层理，是风暴作用的反映；
