The tempo of back-arc basin evolution: Insights from the early Paleozoic Proto-Tethyan North Qilian orogenic belt, northeastern Tibet
Back-arc basins are pivotal sites for the generation and consumption of oceanic lithosphere
in mature intra-oceanic convergent plate margins. However, the processes and mechanisms …

Generation of ultraslow-spreading oceanic crust traced by various mafic blocks from ophiolitic mélange in the Xigaze Ophiolites, southern Tibet
Construction of oceanic crusts in ultraslow-spreading ridges are controlled by detachment
faults, but the specific ways they are determined by detachments remain unclear. Abundant …

Commentary on Jaillard, E.,(2022): Late Cretaceous-Paleogene orogenic build-up of the Ecuadorian Andes: Review and discussion
AM Alemán - Earth-Science Reviews, 2024 - Elsevier
Abstract Although Jaillard's (2022) paper denotes the first attempt to propose a model for the
orogeny build-up of the Ecuadorian Andes, it is based on endorsing the poorly constrained …

Oxidized primary arc magmas: Constraints from Cu/Zr systematics in global arc volcanics
SY Zhao, AY Yang, CH Langmuir, TP Zhao - Science Advances, 2022 - science.org
Arc volcanics are more oxidized than mid-ocean ridge basalts (MORB), but it is debated
whether this is a mantle feature or a result of magmatic evolution. Copper, a sulfur-loving …
