Solid Earth SciencesCollisional orogeny produces large volumes of tonalitic melts at two stages: first, during the oceanic subduction below the continent (continental arc), and again, during the post-collisional stage.

Miocene Crustal Anatexis of Paleozoic Orthogneiss in the Zhada Area, Western Himalaya
Acta Geologica Sinica, 2022AbstractGranitic gneiss (orthogneiss) and Himalayan leucogranite are widely distributed in the Himalayan orogen, but whether or not the granitic gneiss made a contribution to the Himalayan leucogranite remains unclear. In this study, we present the petrological, geochronological and geochemical results for orthogneisses and leucogranites from the Zhada

Oligocene crustal anatexis in the Tethyan Himalaya, southern Tibet
Lithos, 2016Abstract Recent studies in the Xiaru and Malashan gneiss dome of the Tethyan Himalaya, southern Tibet identify that Xiaru and Paiku tourmaline-bearing leucogranite dike formed at ~ 28–29 Ma. Together with ~ 28 Ma Kuday garnet-bearing leucogranites, it is demonstrated that the Himalayan orogenic belt experienced a major episode of crustal melting in ...

Fluid-absent (dehydration) melting of biotite in metapelites in the early stages of crustal anatexis
Contributions To Mineralogy and Petrology, 1988Experimental investigation of the fluid absent melting reaction biotite+plagioclase+A12SiOs+quartz~ garnet + K-feldspar + melt at 10 kbar, indicated that melt- ing began between 760 and 800~ and was extensive at 850 ~ C. This reaction apparently has a positive dP/dT at least up to 10 kbar, compared to a calculated backbending in a simplified system ...
