The Neoproterozoic Throssell Range Group, Western Australia: A Peri‐Marginal Continental Basin in Rodinia and Its Implications for the Centralian Superbasin

Basin Research, Volume 38, Issue 1, January–February 2026.
This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

Upper Cretaceous Seismic Stratigraphy and Magma‐Enhanced Petroleum System of the Offshore Indus Basin

Basin Research, Volume 38, Issue 1, January–February 2026.
Seismic data reveals Cretaceous stratigraphy and hydrocarbon potential beneath volcanic rocks in Offshore Indus Basin, where magmatic intrusions enhanced source rock maturation and hydrocarbon generation by 8%–18% during favourable timing coinciding with Deccan volcanism.

The polyphase Belokurikhinsky granite massif, Gorny Altai: isotope-geochemical study of zircon

Записки Горного института
Based on the isotopic-geochemical analyses of zircons from granites of the Belokurikhinsky massif in the Gorny Altai using the U-Pb method, the ages of three intrusion phases have been determined for the first time: the age of the first phase refers to ...

Localized and Transient Oxygenation of Shallow Oceans of Southwestern Laurentia at the Ediacaran–Cambrian Boundary

Geobiology, Volume 24, Issue 1, January/February 2026.
ABSTRACT The Ediacaran–Cambrian boundary, which precedes one of the most significant biotic diversification events in Earth's history, is associated with a global negative carbon isotope excursion termed the BAsal Cambrian carbon isotope Excursion (BACE).

Ultrahigh‐Temperature Metamorphism and Near‐Isobaric Cooling of Garnet‐Orthopyroxene Granulite Xenoliths in the Sancheong Anorthosite, Yeongnam Massif, Korea

Journal of Metamorphic Geology, Volume 44, Issue 1, Page 20-46, January 2026.
ABSTRACT Elevated heat flow associated with mafic magmatism in accretionary orogens has often been proposed as a driving mechanism for (ultra)high‐temperature (UHT) metamorphism and anatexis. The Sancheong–Hadong complex, located in the southern Yeongnam Massif, Korea, consists of a ca.
