Comparative analysis of the Late Cretaceous to Recent post-breakup basin evolution of the South-American and S-African margin of the southern Atlantic

该项目的重点是对巴西南部近海Peltanie和桑托斯盆地中存档的断裂后构造和地层记录与纳米比亚和安哥拉南部近海断裂后大陆边序列进行区域比较。对弗洛里亚诺波利斯-沃尔维斯海岭火山复合体南部和北部选定的代表性二维地震断面进行构造-地层分析，将提供控制解体后近海边缘发展的关键因素的全面的盆地到盆地文件，包括边缘配置、随时间推移的沉降发展、沉积物流入和储存模式、盆地填充类型（例如盐系统与非盐系统;富碳酸盐系统与碎屑岩为主系统）和海平面波动。将采用构造-地层联合回剥法来综合、量化和衡量上述因素对不同研究地点边缘发育的影响。

This project focuses on a regional comparison between the post-breakup tectonic and stratigraphic record archived in the Pelotas and Santos basins offshore southern Brazil and the post-breakup continental margin successions of offshore Namibia and southern Angola. Tectonic-stratigraphic analysis of selected, representative 2D seismic transects both south and north of the Florianopolis - Walvis Ridge volcanic complex will provide a comprehensive basin-to-basin documentation of the key factors controlling the post-breakup offshore margin development including the margin configuration, subsidence development through time, sediment influx and storage patterns, type of basin fill (e.g. salt vs. non-salt systems; carbonate-rich vs. clastics-dominated systems) and sea-level fluctuations. Combined tectonic-stratigraphic backstripping will be used to integrate, quantify and weigh the influence of the above factors on the margin development at the different study sites.
