Significance of Leucogranitic Gneiss in the Archean Teton Range

open access: yesThe UW National Parks Service Research Station Annual Reports, 2008
In previous years of this project, we have developed the hypothesis that the high-pressure granulites exposed in the Moose Basin area of the Teton Range represent evidence of a 2.7 billion year­old continent-continent collision. We have described gneisses in the Teton Range that show two distinct metamorphic histories. In the northwest there are high­

Radiogenic Heating as the Thermal Driver of Himalayan Crustal Heating During Prolonged Thickening

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The thermal evolution of the crust during continental collision evolves from cold to hot with time, which impacts crustal reworking and differentiation. However, it remains elusive as to the mechanism driving the crust to be hot during the protracted collision.

Geochronology, Geochemistry, and In Situ Sr-Nd-Hf Isotopic Compositions of a Tourmaline-Bearing Leucogranite in Eastern Tethyan Himalaya: Implications for Tectonic Setting and Rare Metal Mineralization [PDF]

open access: yes
Himalayan leucogranite is an excellent target for understanding the orogenic process of the India–Asia collision, but its origin and tectonic significance are still under debate. An integrated study of geochronology, geochemistry, and in situ Sr-Nd-

Une occurrence uranifère à sélénium et bismuth dans la ceinture métamorphique du leucogranite de Mortagne-sur-Sèvre (Vendée) [PDF]

open access: yes, 1980
The Retail mineralized vein is located in metamorphic formations along the Mortagne leucogranite border. It is characterized by three different mineralogical associations which result in three crystallization stages produced by hydrothermal solutions in ...

Late Jurassic Leucogranites of Macau (SE China): A Record of Crustal Recycling During the Early Yanshanian Orogeny

open access: yesFrontiers in Earth Science, 2020
The Yanshanian Orogeny consists of Jurassic to Cretaceous compressional-extensional cycles related to the subduction of the Paleo-Pacific Ocean beneath East Asia. Numerous granitic plutons were emplaced across southeast China at distinct intervals over a

Some progress on understanding the Phanerozoic granitoids in China

open access: yesChina Geology, 2018
: There are large volumes of the Phanerozoic granitoid rocks in China and neighboring areas. In recent years, numerous new and precise U-Pb zircon ages have been published for these granitoids, and define many important magmatic events, such as ca.
