Pliocene-Quaternary crustal melting in central and northern Tibet and insights into crustal flow [PDF]

open access: yesNature Communications, 2016
The role of the low velocity-high conductivity zones (LV–HCZs) in developing the Tibetan Plateau has remained controversial. Here, Wang et al.present new geochemical and petrological data that show the LV–HCZs are sources of partial melt thus giving ...

Dichotomy in crustal melting on early Mars inferred from antipodal effect [PDF]

open access: yesInnovation(China), 2022
Summary: The Martian crustal dichotomy (MCD) between the southern highlands and the northern lowlands is the planet’s most ancient crustal structure, but its origins and evolution remain enigmatic.

Water availability controls crustal melting temperatures

open access: yesLithos, 2021
Although the capacity for water to lower the solidus during crustal melting is well recognised, a modern consensus is that most granitic magmas are generated under fluid-absent melting conditions at temperatures ≥850 °C, and that water has little ...

A modern pulse of ultrafast exhumation and diachronous crustal melting in the Nanga Parbat Massif. [PDF]

open access: yesSci Adv, 2022
We combine monazite petrochronology with thermal modeling to evaluate the relative roles of crustal melting, surface denudation, and tectonics in facilitating ultrafast exhumation of the Nanga Parbat Massif in the western Himalayan syntaxis.

Melting conditions in the modern Tibetan crust since the Miocene

open access: yesNature Communications, 2018
Crustal melting may play a fundamental role in orogenic processes, but quantifying crustal melt remains difficult. Here, the authors combine pressure-temperature paths, electrical conductivity and geophysical data to elucidate the melting conditions in ...

Isolated Crustal Partial Melting in the Southern Tibetan Plateau From H‐κ‐c Method

open access: yesGeophysical Research Letters, 2023
The crustal thickness and average Vp/Vs ratio are basic parameters to understand the current state and the tectonic processes in the Tibetan Plateau (TP).

Metamorphism of Venus as driver of crustal thickness and recycling [PDF]

open access: yesNature Communications
The composition and thickness of the venusian crust and their dependence on thermal gradients and geodynamic setting are not well constrained. Here, we use metamorphic phase transitions and the onset of melting to determine the maximum crustal thickness ...

Melting-induced crustal production helps plate tectonics on Earth-like planets

open access: yesEarth and Planetary Science Letters, 2016
Within our Solar System, Earth is the only planet to be in a mobile-lid regime. It is generally accepted that the other terrestrial planets are currently in a stagnant-lid regime, with the possible exception of Venus that may be in an episodic-lid regime.

The Role of Fluids in Melting the Continental Crust and Generating Granitoids: An Overview

open access: yesGeosciences, 2022
Granite is a distinctive constituent part of the continental crust on Earth, the formation and evolution of which have long been hot research topics.

Neodymium Isotope Constraints on the Origin of TTGs and High-K Granitoids in the Bundelkhand Craton, Central India: Implications for Archaean Crustal Evolution

open access: yesLithosphere, 2022
The Bundelkhand craton in central India consists mainly of abundant high-K granitoids formed at the Archaean-Proterozoic boundary and several enclosed rafts of TTGs (tonalite-trondhjemite-granodiorites) up to 3.5 Ga.
