Impact of the Cretaceous-Paleogene event on sedimentary organic matter in southern high-latitude regions
The Cretaceous–Paleogene (K/Pg) boundary marks one of Earth’s significant mass extinctions, disrupting terrestrial and marine ecosystems. We investigate sedimentary organic matter and geochemical proxies from two high-latitude K/Pg sections: El Puesto (continental, Chilean Patagonia) and Filo Negro (marine, Seymour Isl...

A high-resolution chronology and terrestrial ecosystem record of Early Pliocene Warmth onset in Europe from Camp dels Ninots, NE Iberia
The Early Pliocene Warmth (EPW) was one of the most recent intervals of sustained global temperatures above present, but its expression in European terrestrial environments remains poorly constrained. Here we establish a continental chronological and paleoenvironmental framework for the Camp dels Ninots maar-lake suc...

Quaternary Sedimentary Sequence and Paleoclimatic Evolution in the Southern Yinchuan Basin: Evidence from Sedimentology, Geochemistry, and Detrital Zircon U–Pb Geochronology of ZK01 Borehole
The Yinchuan Basin is situated at the leading edge of the latest northeastward expansion of the northeastern Tibetan Plateau. Sedimentary sequences at basin margins are crucial for understanding basin–mountain coupling relationships, yet systematic studies remain scarce. Here, we present a comprehensive sedimentologica...

A preliminary palynological and magnetic susceptibility record from the southern Sanjiang Plain, NE China: implications for orbital-scale monsoon variability since the Middle Pleistocene
The Sanjiang Plain, characterized by thick Quaternary sedimentary sequences and limited anthropogenic disturbance, represents an ideal archive for regional paleoenvironmental reconstruction. While extensive studies have focused on Holocene variability, the Pleistocene climatic evolution of this region remains inadequ...

Integrated sedimentological and sequence stratigraphic framework of the Paleocene–Eocene Series at Kef Essnoun, Djebel Onk (Northeastern Algeria)
The Paleocene–Eocene succession at jebel Onk, northeastern Algeria, remains poorly understood, despite its significance for reconstructing paleoenvironments during a critical period of global change. Unlike the well-studied equivalent series in the Metlaoui–Gafsa Basin, the Algerian counterpart lacks a robust stratigra...

A comprehensive chronostratigraphic framework for Oligocene and Miocene fossil plant sites of the Pacific Northwest (USA) from U-Pb zircon geochronology and Bayesian age modeling
A wealth of Oligocene to Miocene fossil floras in the Pacific Northwest of the United States—including Washington, Oregon, and Idaho—offers critical proxy evidence of regional terrestrial environments and climate during times of dynamic regional volcanism, tectonics, and global climate. However, the lack of a well-reso...
