The stratigraphic and geochemical record of Playa Cycles: monitoring a Pangaean monsoon-like system (Triassic, Middle Keuper, S. Germany)
Lutz Reinhardt,Werner Ricken +1 more
TL;DR: In this article, the playa cycles of the Middle Upper Triassic Steinmergel-Keuper, located in southern Germany, were studied both in terms of lateral facies shift variations and long-term cyclic patterns.

Dust transport from Patagonia to Antarctica – A new stratigraphic approach from the Scotia Sea and its implications for the last glacial cycle
TL;DR: In this article, two deep-sea cores from the Scotia Sea were used to reconstruct past atmospheric circulation in the southern hemisphere and to resolve a long-standing debate on the interpretation of magnetic susceptibility (MS) records in Southern Ocean (SO) sediment.

Carbon–sulfur–iron relationships and δ13C of organic matter for late Albian sedimentary rocks from the North Atlantic Ocean: paleoceanographic implications
TL;DR: In this article, the authors investigated organic carbon content, δ13C values of the kerogens, maceral composition of the organic matter, C/S ratios, Fe-TOC-S relationships and framboidal pyrite size distribution in order to evaluate processes that led to the accumulation of organic matter-rich black shale deposits.

Interhemispheric ice-sheet synchronicity during the last glacial maximum
Michael E Weber,Peter U. Clark,Werner Ricken,Jerry X. Mitrovica,Steven W. Hostetler,Gerhard Kuhn +5 more
TL;DR: A chronology for the Weddell Sea sector of the East Antarctic Ice Sheet is developed that indicates that the advance to and retreat from their maximum extent was within dating uncertainties synchronous with most sectors of Northern Hemisphere ice sheets.

A comparative study on structural differences of xylite and matrix lignite lithotypes by means of FT-IR, XRD, SEM and TGA analyses: An example from the Neogene Greek lignite deposits
Ioannis K. Oikonomopoulos,Maria Perraki,Nikolaos Tougiannidis,Theodora Perraki,Manfred J. Frey,P. Antoniadis,Werner Ricken +6 more
TL;DR: The FT-IR spectra for both Neogene xylite and matrix lignite samples from six different Greek Lignite deposits (NW Greece) showed significant differences as discussed by the authors.
