Question

Which of the gondwana group show rich in plant fossil?

Answer 1

Origin of Gondwana Rocks:

It is widely accepted that Gondwana Rocks are of fluviatile origin, that is, these have been deposited by streams and rivers in the so called Gondwana basin. The basin itself is thought to have been of the nature of a gradually sinking broad trough where deposition of the sediments was accompanied by the subsidence of the basin (under the load) so that huge accumulations were possible in due course of time. This mode of origin is confirmed by their fossil content as well as their geotectonic (structural) relations with other rocks in the area of occurrence.

The Gondwana Group of rocks form the most important – stratigraphically, geologically and economically—groups of India.
