To the west and northwest, the Sichuan Basin abuts the eastern edge of the Tibet Plateau. Major mountain ranges along this edge include the Daxue Mountains, the Qionglai Mountains, the Min Mountains, and the Longmen Mountains. The Sichuan Basin is separated from the Indian subcontinent to the southwest by the massive Hengduan Mountains, an extension of the Tibetan Plateau. Here, Mount Emei is a significant peak that rises abruptly from the basin floor.
