Why are granitic rocks found in Tibet? Why are shallow marine sedimentary rocks present in the
higher parts of the Himalaya? What will be an ideal response?
Granitic plutons resulted from subduction and partial melting of the Indian plate beneath Eurasia.
Upon impact of India with Eurasia, India’s low density and resistance to subduction caused it to
be underthrust about 2000 km beneath Asia. This underthrusting caused sedimentary rocks
formed in the sea south of Asia to be thrust northward into Tibet.
