Vindhyachal-Baghclkhand Plateau (21° 29′ – 25° I 1’N and 78° 15-84° 15’E) covers an area of about 1, 40,172 sq. km in the central part of the Peninsular Foreland. It is a transition zone incorpo­rating the Vindhyachal and Satpuranchal. The re­gion has general elevation ranging from 150 m to 1200 m with uneven relief.

The main elements of physiography are the scarps of the Vindhyan sandstones between the Ganga plain and the Narmada- Son trough. The Bhanrer and Kaimur (seldorm ex­ceeding 800 m) lie much closer to the trough-axis. Between the two scarps are the plateaus of Satna, Rewa and Mirzapur.

The general horizontality of strata shows no signs of marked disturbance except minor crumplings in the west and tilting to the north. The ridges show massive quartzite cappings and hogback structure.

The Narmada-Son trough is a structural dislo­cation along the junction of the Archaeans and the Bijawars. South of this trough has the eastern exten­sion of the Satpura which is an area of radial drain­age (Amarkantak 1087 m) which marks the shore­line of the Cuddapah sea.

ADVERTISEMENTS:

The whole surface is an assemblage of flat-topped plateaus (Chhindwara, Seoni, Maikal, Deogarh etc), with general elevation between 600-900 m. Among the basins, Singrauli and Dudhi (150-300 m) are Upper Gondwana ba­sins. Several erosion surfaces (300-400 m, 450-550 m and above 600 m) have been identified in the region.

Besides the Narmada and the Son, Durgawati, Karmanasa, Jirggo, Tons, Ken, Belandare and other streams of the region exhibit the dendritic pattern.
