Petrochemistry of Some Granitic Rocks from the Nanga Parbat Massif, NW Himalaya, Pakistan
Abstract
Petrographic notes and chemical analyses are given for ten granitic rocks from the Nanga Parbat massif, northwestern Himalayas. Chemical and normative variation diagrams are used to show that the granitic rocks originated through alkali metasomatism of metasediments, a specific chemical change beidg controlled by original composition of the particular lithologic facies Scanty previous data are included for comparison.
