TL;DR: It is shown that chemical weathering in Central Africa, reconstructed from geochemical analyses of a marine sediment core, intensified abruptly at the same period, departing substantially from the long-term weathering fluctuations related to the Late Quaternary climate.

TL;DR: In this article, the authors report rare earth element (REE) and neodymium (Nd) isotope data for the organic fraction of sediments collected from various depositional environments, i.e., rivers, estuaries, coastal seas and open-ocean settings.

TL;DR: In this article, the authors analyzed size-fraction of sediment samples collected near the mouth of 53 rivers worldwide to better understand the factors controlling the distribution of Hf and Nd isotopes in sediments.

TL;DR: The IGUANES cruise on the R/V L'Atalante along the Demerara passive transform margin off French Guiana and Surinam as discussed by the authors highlights the lateral variability of the 350 km-long Guiana-Surinam transform margin due to the presence of a releasing bend between two transform segments.
