摘要: 黄骅拗陷沙三期为强烈断陷期,广泛发育泥石流碎屑流、颗粒流、浊流和滑塌五种块体重力搬运沉积,形成近岸扇、近岸水下扇和湖底扇三种以正旋回为主的沉积体。本文以柏格庄—柳赞、港中和羊二庄地区为重点,全面分析研究了沙三期各扇体的块体重力沉积特征、扇体的发育演化及分布,建立了各种扇的沉积模式。

Abstract: In S3 phase Huang Hua depression was in a period of intense fault and subside.There widely existed the deposits of debris flow,clastic flow, grain flow, turbite flow and slumping, They made up three kinds of deposition systems of near bank fan, subqueous near bank fan and sublake fan in the main form of the normal cycle sequence. Mainly taking Bai Ge Zhuang---Lou Zhan, Yang Er Zhuang and Gang Zhong districts for example, this paper makes detailed research on the deposition characteristics of gravity flow, the evolution,the contribution and deposition models of all kinds of fan systems.
