The authors undertook fieldwork in 2004 and 2006 in the Pangong
metamorphic complex especially in the section from Tangtse to Pangong Tso (Fig. 1). The mineralogy and phase petrology of the
garnet–kyanite–staurolite gneiss have been studied in order to decipher
the regional P–T evolution using isochemical phase diagrams.
Muscovite and biotite in the gneisses and associated leucogranites
were dated by the K–Ar method. We present these results in order
to demonstrate the relevance of multiple garnet zonation and chemistry
to the tectono-metamorphic evolution of the Pangong complex
in relation to the subduction–collision tectonics of the Shyok suture
and the development of the Karakoram fault (Fig. 1).
