Explanation:

The northern boundary of the Peninsular Block may be taken as an irregular line running from
Kachchh along the western flank of the Aravalli Range near Delhi and then roughly parallel to
the Yamuna and the Ganga as far as the Rajmahal Hills and the Ganga delta. Apart from these,
the Karbi Anglong and the Meghalaya Plateau in the northeast and Rajasthan in the west are
also extensions of this block. The north-eastern parts are separated by the Malda fault in West
Bengal from the Chotanagpur plateau. Since the Cambrian period, the Peninsula has been
standing like a rigid block with the exception of some of its western coast which is submerged
beneath the sea and some other parts changed due to tectonic activity without affecting the
original basement. As a part of the Indo-Australian Plate, it has been subjected to various
vertical movements and block faulting. The rift valleys of the Narmada, the Tapi and the
Mahanadi and the Satpura block mountains are some examples of it.
