Abstract Here are described the analyses of sediments from the lower slope of the Pelotas Basin in the southern Brazilian continental margin, southwestern Atlantic. The samples were obtained from the core SIS-249, collected adjacent to the Rio Grande Terrace (RGT) at a water depth of 2091 m, an area poorly known in terms of sedimentary characteristics compared to the oil and gas-rich basins to the north. The age model indicates that the sampled sediments were accumulated during the last glacial period, between 112.5 and 34.47 ka (MIS 5 to MIS 3). The fine (

巴西大陆边缘南部里奥格兰德阶地下坡的晚更新世沉积物堆积

摘要 这里描述了巴西南部大陆边缘、大西洋西南部佩洛塔斯盆地下坡沉积物的分析。样品取自 SIS-249 岩心,在里奥格兰德台地 (RGT) 附近采集,水深为 2091 米,与北部富含石油和天然气的盆地相比,该地区在沉积特征方面知之甚少。 . 年龄模型表明采样的沉积物是在最后一个冰期积累的,介于 112.5 至 34.47 ka(MIS 5 至 MIS 3)之间。罚款(
