Congo River sand and the equatorial quartz factory
Eduardo Garzanti,Pieter Vermeesch,Giovanni Vezzoli,Sergio Andò,Eleonora Botti,Mara Limonta,Pedro Dinis,Annette Hahn,Daniel Baudet,Johan De Grave,Nicole Kitambala Yaya +10 more
TL;DR: The origin of sandstone consisting exclusively of quartz and most durable heavy minerals has been investigated in sedimentary petrology as discussed by the authors, showing that approximately 10% of the sand supplied to the Atlantic Ocean is generated by rapid fluvial incision into the recently uplifted Atlantic Rise.
Microsedimentological characterization using image analysis and μ-XRF as indicators of sedimentary processes and climate changes during Lateglacial at Laguna Potrok Aike, Santa Cruz, Argentina.

TL;DR: In this paper, a high-resolution study of lacustrine sediments from Laguna Potrok Aike, Santa Cruz province, Patagonia, Argentina, was conducted for the Lateglacial period using concurrent X-Ray Fluorescence (XRF) and Scanning electron microscope analyses.

TL;DR: The first record of denitrification evolution since Late Miocene is presented in the Eastern Arabian Sea, where the SAM generates moderate surface water productivity, based on the samples retrieved during the International Ocean Discovery Program (IODP) Expedition 355.
Sea level-controlled sediment transport to the eastern Arabian Sea over the past 600 kyr: Clay minerals and SrNd isotopic evidence from IODP site U1457
Zhaojie Yu,Zhaojie Yu,Christophe Colin,Shiming Wan,Rajeev Saraswat,Lina Song,Zhaokai Xu,Peter D. Clift,Huayu Lu,Mitchell W Lyle,Denise K. Kulhanek,Annette Hahn,Manish Tiwari,Ravi Mishra,Serge Miska,Anil Kumar +15 more
TL;DR: In this article, the clay mineralogy and Sr Nd isotopic compositions have been analyzed for the detrital fraction of sediments from IODP Site U1457 located in the Laxmi basin, eastern Arabian Sea to constrain the sediment sources and reconstruct a high-resolution record of sediment export to the Indus deep-sea fan over the past 600 kyr.

Sources, transport and deposition of terrestrial organic material: A case study from southwestern Africa
Nicole Herrmann,Arnoud Boom,Andrew S. Carr,Brian M. Chase,Robyn Granger,Annette Hahn,Matthias Zabel,Enno Schefuß +7 more
TL;DR: In this paper, plant wax derived n-alkanes and their compound-specific δ13C in soils, flood deposits and suspension loads from regional fluvial systems and marine sediments are analysed to characterize the origin of terrestrial organic material in the southwest African mudbelt.
