The recent observed seismicity in the peninsular shield region has attracted the
Geoscientific community to update the seismic zoning map of India. The lineament
fabric of any region gives useful informations about the status of  the stress pattern
and also indirect information about the subsurface configuration. The present work
have been carried out to study the lineament fabric of central-eastern part of M.P.
using IRS-1B LISS-I data. The two distinct lineament patterns have emerged from the
study are the ENE-WSW and NW-SE trends. The Satpura lineaments truncate the
Vindhyan lineaments which extend uninterruptedly and hence the Satpura  trend
appear to be younger than the other two trends. The Son-Narmada and Tapti
lineaments appear to be crustal lineaments of continental proportion perhaps extend
right up to the Moho. These lineaments exist since the early Proterozoic and have been
reactivated during different periods in the geologic history and highly influences the
sedimentary and structural history of the area. From the nature of these lineaments
and distribution of rock formations, it has been interpreted that the Satpura forms a
horst, flanked on north by the Narmada graben and on south by the Purana graben,
respectively. The Satpura horst appears to be still rising. The Bundelkhand block
(Northern Tectonic Block) seems to be tectonically stable block and unrelated to
southern tectonic block which have apparently evolved independent of each other.
