通过对综合古生物和非古生物资料的古生态信号进行解释，对莫桑比克近海4区钻井的古近系演替进行了沉积史重建。实现了高分辨率综合生物地层格架。基于孢形、有孔虫和钙质纳米化石的经验指标，结合岩性测井曲线和矿物学数据，得到了相应的经验指标。根据古温度、水深、离海岸线的距离、地表径流强度和入海河流流量等因素进行了推断。全球气候趋势、内陆构造隆升、海平面上升旋回、深海沉积和浊积岩沉积之间的联系已被广泛研究。
Summary The reconstruction of the depositional history of the Paleogene succession from wells drilled in Area 4, offshore Mozambique, was carried out by interpreting paleoecological signals from integrated paleontological and non-paleontological datasets. A high-resolution integrated biostratigraphic framework was realized. Empirical indices based on palynomorphs, foraminifera and calcareous nannofossils were derived from this study and integrated with the lithological log curves and the mineralogical dataset. Inferences were made in terms of paleo-temperature, bathymetry, distance from the coastline, intensity of surface runoff and fluvial discharge into the sea. Connections among global climatic trends, tectonic uplift of the hinterland, eustatic cycles, sediment accumulation and turbidite deposition in deep marine settings have been extensively investigated.
