Yarkand River
This natural physical landmass in South Asia is the dry-land portion of the Indian Plate, which has been relatively isolated from the rest of Eurasia. The Himalayas (from Brahmaputra River in the east to Indus River in the west), Karakoram (from Indus River in the east to Yarkand River in the west) and the Hindu Kush mountains (from Yarkand River westwards) form its northern boundary. In the west it is bounded by parts of the mountain ranges of Hindu Kush, Spīn Ghar (Safed Koh), Sulaiman Mountains, Kirthar Mountains, Brahui range, and Pab range among others, with the Western Fold Belt along the border (between the Sulaiman Range and the Chaman Fault) is the western boundary of the Indian Plate, where, along the Eastern Hindu Kush, lies the Afghanistan–Pakistan border. In the east, it is bounded by Patkai, Naga, Lushai and Chin hills. The Indian Ocean, Bay of Bengal and Arabian Sea forms the boundary of the Indian subcontinent in the south, south-east and south-west.
