Geochemical proxy records on terrestrial input, redox conditions, and organic matter preserved in a tropical paleo-lagoon during the mid-Holocene (Laguna de Bai, Philippines)

First foraminiferal record and multi-proxy reconstruction of paleoenvironmental changes in the Gulf of Gdańsk (SE Baltic Sea) over the last 5000 years

We present new multi-proxy data investigating major environmental transitions over the last 5 kyr BP, based on a sediment core retrieved from the Gulf of Gdańsk (SE Baltic Sea). Between 5 and 1.5 kyr BP, the bay experienced low-energy depositional conditions, which were disrupted around 4 kyr BP, likely due to intens...

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...

Carbon and nitrogen isotopes reveal organic matter provenance and late holocene dynamics off northeastern Hainan Island

Paleoenvironmental Controls on Organic Matter Enrichment in Marine–Continental Transitional Shales of the Upper Carboniferous Yanghugou Formation, Western Ordos Basin

Organic matter enrichment in marine–continental transitional shales is influenced by volcanism, continental weathering, and paleoceanographic evolution, but their interactions during the Late Paleozoic Ice Age (LPIA) remain unclear. Mineralogical, elemental, and organic geochemical data from the Upper Carboniferous Yan...

Paleomagnetic and oxygen isotopic records from the upper Pliocene marine succession in the Western North Pacific: insights into the Mammoth and Kaena subchrons

Robust chronological frameworks that integrate paleomagnetic and oxygen isotope records are essential to stratigraphic correlation across diverse geological records. However, such records remain scarce for the Late Pliocene. This issue is particularly evident in the western North Pacific region around Japan, where many...

Terrestrial paleoenvironments and paleoclimate during the Miocene climate optimum at Buluk, East Turkana, Kenya

Understanding the environmental and climatic context of Neogene fossil localities in eastern Africa is critical for determining potential drivers of evolution in our hominoid ancestors and their floral and faunal communities. In this study, we reconstructed paleoenvironments and paleoclimate conditions for strata assoc...
