Greater Maldive Ridge

The Maldive Ridge is tectonic and not affected by natural disasters. This ridge, situated in the west Indian Ocean is in the south-west of India, has received relatively little attention. The study can help reconstruct the earliest Gondwanaland breakup and distribution, resulting in the present condition of territories, broken coastal pieces, and the establishment of coastal areas in the Indian Ocean. The study provides insights into the Wider Maldive Ridge’s earth’s crust infrastructure, lithospheric monetary benefits, and geological evolution. In the given article, we have mentioned all the essential information about Greater Maldive Ridge and Reconstructing Gondwanaland Break Up.

What is the Greater Maldive Ridge?

• The Greater Maldive Ridge is a tectonic hillside that is not impacted by natural disasters. This hillside is situated south of India in the west Indian Ocean. It expands from the Indian Peninsula’s western coast to the Arabian-Indian (or Carlsberg) Crust
• The Maldive Ridge’s mountain ranges rise just above the water, trying to form coastal islands (atolls) known as the Laccadive Islands, Maldive Islands, and Group of islands Outlying islands. The study can help reconstruct the initial Gondwanaland breakup and distribution, resulting in the present format of territories, coastal shards, and the establishment of the earth’s oceans in the Indian Ocean
• The Indian Institute of Geomagnetism, Mumbai, an independent foundation of the National Science And Technology, Government of India, has for the first time sketched potential geographical passes along the GMR using spacecraft higher-pressure data. The researchers theorised that an oceanic crust could support the GMR. Their research findings could help researchers better understand the plate-tectonic development of the Indian Ocean

About the study:

• The research was done utilising the Indian institute of geomagnetism, Mumbai, a self-reliant institute of the government of India’s department of science and technology

• The look used satellite-derived excessive-resolution gravity statistics for the first time to map possible geological go-sections alongside the GMR. 

• The researchers hypothesised that the GMR might be supported by an oceanic crust. The outcome of their studies ought to help researchers better understand the plate-tectonic evolution of the Indian ocean

• The Study can help reconstruct the authentic Gondwanaland breakup and dispersal, which resulted in the cutting-edge configuration of continents, continental fragments, and the formation of ocean basins in the Indian ocean

• It describes the crustal architecture of the greater Maldive ridge segment of the larger Chagos-Laccadive ridge (CLR) machine and the nation of gravitational equilibrium between the earth’s crust and mantle (isostasy)

• The look, which changed based on the translation of gravity anomalies (small variations in gravity pull) with broadband seismic and seismic refraction records, supplied the first 3-dimensional image of the variant of moho along the Maldive ridge and the adjacent ocean basins

What is the importance of this study?

Scientists studied the Gondwanaland breakup and dispersal that led to the present-day configuration of continents, continental fragments, and the formation of ocean basins in the Indian Ocean. The Study can help reconstruct the authentic Gondwanaland breakup and dispersal, which resulted in the cutting-edge configuration of continents, continental fragments, and the formation of ocean basins in the Indian ocean. The first of these stages was the separation of Madagascar from Africa and India. The second phase was the movement of India northward and then eastward in the Indian Ocean. The third stage was the splitting of Madagascar from India. Scientists can find out more details about the breakup and dispersal of Gondwanaland, which could help map the geological history of the Indian Ocean.

The study provides new insights into the breakup and dispersal of the Gondwanaland that led to the present-day configuration of continents, continental fragments, and the formation of ocean basins in the Indian Ocean. Studying the Indian Ocean continental drift history can reveal the absolute timing of their break-up and the configuration of India and its surrounding continents. Unlike previous studies, an international team of researchers considered the rate-dependent nature of the break-up of Gondwanaland in their study.

Conclusion

According to a recent study, the GMR is a product of the Indian plate moving northwards at a faster rate than the underlying oceanic lithosphere, a trend that has caused the oceanic crust to thicken over millions of years. This is something that has been called a ‘hotspot’, which is an area where magma rises to the surface and pushes the crust up as it cools. The GMR is also the home of the world’s second deepest oceanic trench, where the Indian plate dives beneath the Burma microplate. The region is characterised by a number of active submarine volcanoes, which are directly connected to the tectonics of the adjacent plates and the underlying mantle.
