An Indian researcher has traced the tectonic evolution and the nature of the Greater Maldive Ridge (GMR) — a very crucial geodynamic features in the western Indian Ocean whose origin has been the centre of many a scientific debate.
- The study can help reconstruct the original Gondwanaland break up and dispersal that led to present-day configuration of continents, continental fragments, and formation of ocean basins in the Indian Ocean.
- The depth to the boundary between the earth’s crust and the mantle or the Mohorovicic discontinuity (Moho) over the GMR was systematically mapped along with the finer variation of effective elastic thickness (Te) at the place.
- The research related to The variations and isostatic compensation has been published recently in the journal ‘Gondwana Research’.
- The research work carried out by Dr. Priyesh Kunnummal under the guidance of Dr. S.P. Anand.
About Maldive Ridge
- The Maldive Ridge is an aseismic ridge that is not associated with earthquake activities. This ridge, located in the western Indian Ocean, southwest of India, is not well investigated.
- It is of paramount importance to gain knowledge on the structure and geodynamics of aseismic ridges (as it provides valuable inputs towards understanding the evolution of ocean basins).
