The evolution of rock-forming minerals (orthopyroxene, garnet, biotite, and amphibole) is studied in successive generations of granites and leucosomes. It is shown that the trace element partition coefficients between solid phases and melt are govern

The P–T conditions of Early Paleozoic metamorphism in the Sangilen block of the Tuvino-Mongolian Massif (southeastern part of the Central Asian Mobile Belt) achieved a value of 910–950°C and 3–4 kbar, which corresponded to the conditions of ul

Based on the density functional theory (DFT), frequency shifts of garnet end-members upon isotope substitutions (18O/16O, as well as “non-traditional” stable isotopes) were calculated. According to the calculations, the temperature dependencies o

The possibilities of using the average compositions of tonalite–trondhjemite–granodiorite association rocks (TTG), which make up a significant part of the Archaean continental crust, have been examined. The results of the TTG average compositions
