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

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

Crustal melting in orogenic belts revealed by eclogite thermal properties. [PDF]
Nat Commun, 2022 AbstractPartial melting in the continental crust may play a critical role on the behavior of continents during collision. However, the occurrence of partial melt in orogenic continental crust is not well understood. Since the temperature of the orogen is controlled by the thermal properties of constituent rocks, we measured the thermal conductivity and

Crustal melting and continent uplift by mafic underplating at convergent boundaries. [PDF]
Nat CommunThe thick crust of the southern Tibetan and central Andean plateaus includes high-conductivity, low-velocity zones ascribed to partial melt. The melt origin and effect on plateau uplift remain speculative, in particular if plateau uplift happens before continental collision.

Isolated Crustal Partial Melting in the Southern Tibetan Plateau From H‐κ‐c Method
Geophysical 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]
Nature CommunicationsThe 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 ...

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

Melting by numbers: Assessing the effective melt fertility of crustal rocks [PDF]
Lithos, 2021 Partial melting of rocks and the corresponding metamorphic reactions can be simulated through a Lagrangian description, which considers a discrete mineral distribution at sample scale and an infinite heat source. Our model aims to determine the effective melt productivity of crustal rocks linked to texture and composition of the source. In addition, it

Lithosphere, 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.
