ABSTRACT The Early Jurassic Polaris Alaskan-type intrusion in the Quesnel accreted arc
terrane of the North American Cordillera is a zoned, mafic-ultramafic intrusive body that …

The “wet” silicate solidus of mantle peridotite defines the initial melting temperature of
Earth's mantle under water‐saturated conditions and the second critical endpoint (SCEP) …

The Neoproterozoic tectonic setting of the West Cathaysia terrane and its relationship with
the Yangtze Block are critical to understanding the formation and tectonic evolution of South …

The second part of this article can be found here: 10.3389/feart. 2023.819109 (DOI). At the
late Triassic New Afton alkalic porphyry Cu-Au deposit (British Columbia, Canada), pyrite is …

New studies in the central and southern parts of the Murchison Domain in the Youanmi
Terrane, western Yilgarn Craton, reveal previously unidentified igneous rock types in …

Plume-derived high-MgO lavas provide important information on the lithological, thermal
and chemical variations of Earth's deep mantle. Here we present results from detailed field …

Olivine in cumulates from the Early Jurassic Polaris Alaskan-type ultramafic-mafic intrusion
in the North American Cordillera displays a wide range of textures and compositions …

The chemical composition of a basalt is a critical indicator of mantle thermal condition and
tectonic setting. The Yangtze Block, which is a part of the Rodinia supercontinent, formed …

Ultramafic magmas (MgO≥ 18 wt%) are generally thought to be primary mantle melts
formed at temperatures in excess of 1600° C. Volatile contents are expected to be low, and …

A method was developed for the quantitative estimation of the content of trapped melt in
various dunite types and the composition of this melt on the basis of the major-and trace …
