- Abstract
The Shyok-Darbuk section of eastern Ladakh forms a part of the Shyok Suture Zone, and is dominantly comprised of Early Eocene orthogneisses and mafic enclaves, and Miocene felsic granites and migmatites. The aim of the present study is to establish genetic linkage between leucosome of the migmatites from mixed zone and the felsic granite in the Darbuk region (DFG). It is observed that, partial melting, with or without segregation of initial melts, seems to be the main cause for the generation of felsic melts as represented by leucosomes and felsic granites. Leucosomes are considered as felsic partial melts that were retained in the partially molten zone (migmatite), and that the complex intrusive networks of melt channels in the migmatite region are considered to merge and coalesce during their ascent to upper crustal levels resulting in stocks and plutons of felsic granites that are observed in the Darbuk region.
