摘要
在对黄骅坳陷板桥—北大港地区重力流沉积特征深入研究的基础上,详细描述了该区重力流沉积的岩石学特征、结构特征、构造特征以及生物特征。通过单井沉积剖面特征研究,分析了浊积岩发育的一般规律,识别出深水浊积扇沉积和重力流水道沉积等2种类型的沉积物重力流;并进一步分析了沉积微相、沉积组合序列,建立了浊积岩沉积序列模式,探讨了形成沉积物重力流的环境特征。
Based on the research of the gravity flow deposit characteristics in Banqiao-Beidagang area in Huanghua Depression, the characteristics of gravity flow deposit in the aspects of petrology, texture, structure and biology are detailedly described. According to the study of single well sedimentary section, the general development rule of turbidite is analyzed. Two types of sediment gravity flows are identified, which are deep water turbidite fan and gravity flow channel sediment. The sedimentary mirofacies and sedimentary assemblage are also analyzed, and the turbidite sedimentary sequence model is established. The environment characteristics for sediment gravity flow forming are discussed.
