Journal ArticleDOI
Constraints on the depths and temperatures of basaltic magma generation on Earth and other terrestrial planets using new thermobarometers for mafic magmas
TL;DR: In this article, a thermobarometer based on magma Si and Mg contents was used to estimate the pressures and temperatures of basaltic magma generation on Earth and other terrestrial planets.
Journal ArticleDOI
Copper systematics in arc magmas and implications for crust-mantle differentiation.
Cin-Ty A. Lee,Peter Luffi,Emily J. Chin,Romain A. Bouchet,Romain A. Bouchet,Rajdeep Dasgupta,Douglas M. Morton,Véronique Le Roux,Véronique Le Roux,Qing-Zhu Yin,Daphne Jin +10 more
TL;DR: The redox state of arc magmas is tracked from mantle source to emplacement in the crust on the basis of copper’s (Cu) affinity for reduced sulfur phases, suggesting that the formation of sulfide-bearing cumulates under reducing conditions may be a critical step in continent formation.
Journal ArticleDOI
Building and Destroying Continental Mantle
TL;DR: In this paper, the authors show that continents are underlain by highly melt-depleted peridotites, which result in a chemically distinct boundary layer that is intrinsically buoyant and strong (owing to dehydration).
Journal ArticleDOI
The redox state of arc mantle using Zn/Fe systematics
Cin-Ty A. Lee,Peter Luffi,Véronique Le Roux,Rajdeep Dasgupta,Francis Albarède,Francis Albarède,William P. Leeman,William P. Leeman +7 more
TL;DR: It is shown that Zn/FeT is redox-sensitive and retains a memory of the valence state of Fe in primary arc basalts and their mantle sources, suggesting that the higher oxidation states of arc lavas must be in part a consequence of shallow-level differentiation processes, though such processes remain poorly understood.
Journal ArticleDOI
Near-Ultrahigh Pressure Processing of Continental Crust: Miocene Crustal Xenoliths from the Pamir
Bradley R. Hacker,Peter Luffi,Valery Lutkov,V. Minaev,Lothar Ratschbacher,Terry Plank,Mihai N. Ducea,Alberto Patino-Douce,Michael McWilliams,James R. Metcalf +9 more
TL;DR: Xenoliths of subducted crustal origin hosted by Miocene ultrapotassic igneous rocks in the southern Pamir provide important new information regarding the geological processes accompanying tectonism during the Indo-Eurasian collision as mentioned in this paper.
