Covariation between molybdenum and uranium isotopes in reducing marine sediments

Mingyu Zhao et al.

Summary: The study found enrichments of isotopically altered molybdenum and uranium in reducing sediments from the Bering Sea, likely indicating a close association between the reduction of U and Mo and organic carbon degradation.

The Devonian-Carboniferous transition at Borkewehr near Wocklum (northern Rhenish Massif, Germany) - a potential GSSP section

Sven Hartenfels et al.

Summary: The Borkewehr section is the best and most complete Devonian/Carboniferous Boundary succession in the Rhenish Massif of Germany. It provides important data on stratigraphy, biostratigraphy, and climate change, which contributes to the understanding of global geological and biological evolution.

Mercury evidence of intense submarine volcanism and hydrothermal activity during a mid-Tournaisian anoxic event in the Carnic Alps

Michal Rakocinski et al.

Summary: Through high-resolution inorganic geochemistry and framboidal pyrite analyses, it was found that the mid-Tournaisian event in the Carnic Alps was associated with widespread anoxic/euxinic conditions and intense volcanic activity. Additionally, significantly anomalous Hg content was observed for the first time during this period.

Reconstructing the Variscan Terranes in the Alpine Basement: Facts and Arguments for an Alpidic Orocline

Michel Faure et al.

Summary: The existence of the Variscan belt in the Alpine basement has been acknowledged, but its correlation to the litho-tectonic domains outside of the Alpine chain is still disputed. By studying various geological units, a preliminary reconstruction of the Variscan orogen in the Alpine basement can be made.

The Devonian-Carboniferous boundary in the Carnic Alps (Austria and Italy)

Claudia Spalletta et al.

Summary: The section discusses four sections in the Carnic Alps that expose rocks spanning the Devonian-Carboniferous boundary, primarily consisting of limestone with interruptions of black shales. The data from these sections, including conodont biostratigraphy, biofacies, and geochemistry patterns, confirm the suitability of the proposed timeline for defining the revised Devonian-Carboniferous boundary by the DCB working group.

Mercury fluxes record regional volcanism in the South China craton prior to the end-Permian mass extinction

Jun Shen et al.

Summary: The study suggests that regional volcanic activity in the South China craton was influenced by the Siberian Traps large igneous province magmatism, possibly contributing to major biotic and environmental stresses associated with the Permian-Triassic boundary mass extinction, with four distinct mercury enrichment intervals identified. Evidence of strong volcanism in the Tethyan region is found to have started about 2 million years before the latest Permian mass extinction event.

Review of Devonian-Carboniferous Boundary sections in the Rhenish Slate Mountains (Germany)

R. Thomas Becker et al.

Summary: This study reviews 30 Devonian-Carboniferous Boundary sections of the Rhenish Slate Mountains and adjacent subsurface areas, focusing on litho-, event, conodont, ammonoid, sequence, and chemostratigraphy. It refines the terminology of the Hangenberg Crisis Interval and distinguishes various conodont and ammonoid zones within different intervals. The study also highlights the subdivision and characteristics of different subzones within the defined intervals.

Was climatic cooling during the earliest Carboniferous driven by expansion of seed plants?

Bo Chen et al.

Summary: The expansion of land plants is believed to have played a key role in triggering the Late Paleozoic Ice Age (LPIA), with limited evidence linking climatic events to terrestrial floral changes. Analyses from the lowermost Carboniferous of South China and Vietnam show that climatic cooling coincided with perturbations to the global carbon cycle, continental weathering regimes, and a major diversification episode among seed plants. These findings suggest that terrestrial floral changes triggered intensified weathering of basalts, enhanced marine productivity, and reduced atmospheric pCO2, leading to global cooling in the Early Carboniferous.
