Abstract The possibility that the Proto‐Tethys Ocean may have undergone intra‐oceanic subduction during ocean closure remains poorly constrained due to a lack of geological evidence for a mature intra‐oceanic arc. Here we present new geochemica

New whole-rock major and trace element geochemical, zircon U-Pb geochronological, and Hf isotopic data from gabbroic rocks in New Zealand’s mid-Permian Dun Mountain ophiolite belt (DMO) provide insight into the evolution of subduction systems and e

The North Qaidam belt is an important polymetallic metallogenic belt in the northwestern region of China. However, the tectonic setting and age of related VMS deposits remain debated. Here we performed an integrated analysis of field relationship, ge

The identification of marine alkenones and anomalously high carbonate carbon isotopic values in sediments suggest the Qaidam Basin in the northern Tibetan Plateau was uplifted from sea level to its present altitude since the Mid-Miocene.

The formation and tectonic evolution of mafic oceanic crust can be determined through dating of calcite amygdules using U-Pb geochronology as well as geochemistry and biostratigraphic observations, according to a study of the New England Orogen, Aust

Although live birth evolved repeatedly in other clades, it has not been found in archosauromorphs, the group including modern birds and crocodilians. Here, the authors describe a fossilized pregnantDinocephalosaurusfrom ∼245 million years ago, prov

A diverse and well-preserved radiolarian assemblage from the Malongulli Formation, New South Wales, Australia, contains 13 species representing 10 genera and six families. One new genus, Wiradjuri, is introduced to accommodate pre-Devonian single-she
