Complete information on Telangana Plateau of Peninsular Uplands

ADVERTISEMENTS:

Telangana Plateau or Andhra Plateau (12° 14-19° 54’N and 76° 50′-81° 50’E) covers 2,04,882 sq. km of area in Andhra Pradesh (north-south length 810 km, east-west width 535 km). Geologically the region consists of a peneplained part of die Peninsu­lar block mainly comprising gneissic complex of pre-Cambrian origin. Dharwar formations occur in Anantapur district, while Cuddapah rocks are seen in Cuddapah, Kurnool, NeUote, Guntur and Anantapur districts.

The Gondawanas appear in the Godavari basin while northern and western are covered by the Trappean lava. The region has two small physiographic units: (i) Telangana, and (ii) Rayalaseema Upland. The Telangana is a long belt of peneplains mainly developed over the gneissic rocks.

It has an average altitude between 300 m and 600 m with general slope towards the east. Its northern and north-eastern mar­gin is occupied by the Godavari valley which is distinct due to its faulted structure. The Hyderabad plateau around the metropolis is conspicuous by its imposing position and laterite and lava deposits.

ADVERTISEMENTS:

The Rayalaseema Upland is divided by the Penner into two sub-units. The former including most of Kurnool and western part of Anantapur district is a completely peneplained surface devel­oped on the gnessic basement.

The Rayalaseema Plateau is a vast tableland forming northward exten­sion of the Karnataka Plateau. Here the monotony of the plateau is broken by the narrow valleys of the Chitravati and Papaghni.
