Geophysical characterization of mantle melting anomalies: a crustal view [PDF]

open access: yes, 2007
18 pages, 4 figures, 1 tableAt present there is no single “unified theory” capable of explaining the variety of geological, geophysical, and geochemical observations that characterize what is generically known as hotspot magmatism.

Crustal Melting and the Flow of Mountains [PDF]

open access: yesElements, 2011
International audienceAs the continental crust thickens during mountain building, it can become hot enough to start melting, leading to a profound reduction In its strength.

Geochemical Insights into Crustal Melting in the Bhutan Himalaya [PDF]

open access: yes, 2016
Crustal melting and granitic intrusions are characteristics of many continental collision zones. The processes, sources and timing of melt generation in collision zones are critical to understanding crustal and tectonic evolution.

Crustal melting in orogenic belts revealed by eclogite thermal properties. [PDF]

open access: yesNat 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]

open access: yesNat Commun
The 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.

Melting by numbers: Assessing the effective melt fertility of crustal rocks [PDF]

open access: yesLithos, 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

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Behavior of apatite in granitic melts derived from partial melting of muscovite in metasedimentary sources

open access: yesChina Geology, 2021
: Fluid-absent and fluid-fluxed melting of muscovite in metasedimentary sources are two types of crustal anatexis to produce the Himalaya Cenozoic leucogranites.

Geochemistry of Precambrian dyke swarms in the Singhbhum craton, India: Implications for recycled crustal components in the mantle source

open access: yesFrontiers in Earth Science, 2023
The Singhbhum craton, eastern India records multiple stages of emplacement of Precambrian dyke swarms with contrasting petrogenetic models proposed for their formation.
