埕东凸起西南坡沙三段砂砾岩体坡积相沉积模式
Depositional model of slope wash facies of Es, glutenite in the southwest slope of Chengdong uplift
摘要
Abstract
Slope wash facies sedimentation refers to a type of band sedimentation of weathering products in piedmont by rolling down the steep slope of faulted lake basin under actions of water, wind and gravity, with glutenite as dominant lithology, often associated with alluvial fan and fan delta. Slope wash usually piles up closely on piedmont base rock and is poorly sorted and stratified. The glutenite body in lower Es, of Cheng 193 block in the southwest slope of Chengdong uplift is taken as an example to study the sedimentary characteristics of slope wash facies by means of core observation, analogous outcrop description and FM1 analysis. The grain sequence of slope wash is analyzed, and a depositional model is established for the slope wash facies in the study area. This research is of great significance to understanding of sedimentary characteristics of slope glutenite in faulted lake basin.关键词
