摘要:
提要:通过研究渤海湾及周边地区中生代南部典型露头剖面的沉积特征及中部岩相古地理特征,认为中生代渤海湾地区由一系列受到断层严格控制的断陷盆地组成,主要发育冲积扇-河流-湖泊沉积体系,湖泊内部包括滨浅湖、滩坝和半深湖等亚相;经历了由冲积扇-河流沉积体系向上演化为湖泊沉积体系,再逐渐演化为冲积扇-河流沉积体系的过程;欧亚构造域的西伯利亚板块、扬子板块与华北板块的挤压拼接在渤海湾地区侏罗纪盆地充填中起到主要的控制作用;郯庐断裂的左行走滑在渤海湾地区白垩纪盆地充填中起到主要的控制作用。

Abstract:
Abstract:Study of the sedimentary characteristics of a typical outcrop section in the south of the Mesozoic Bohai Gulf area and its surrounding areas and lithofacies and paleogeography in the central part of the study area shows that the Mesozoic Bohai Gulf area consists of a series of downfaulted basins controlled strictly by faults, where there is mainly developed an alluvial fan-river-lake sedimentary system lakeshore-shallow lake, beach-bar and semi-deep lake subfacies occurring inside the lake. The alluvial fan-river sedimentary system evolved upward into a lake sedimentary system and then again gradually evolved into an alluvial fan-river sedimentary system. The compressional amalgamation of the Siberian plate,Yangtze plate and North China plate in the Eurasian tectonic domain played a main controlling role in the Jurassic basin filling in the Bohai Gulf area and the strike-slip motion of the Tanlu fault played a main controlling role in the Cretaceous basin filling in the gulf area.
