According to the Maritime Zones Act 2005, natural resources refer to minerals and other non-living materials found in the subsoil and seabed and the marine organisms in a sedentary state, that is, they are unfit for movement when they are harvested or depend on water or soil movement for displacement .
The island of Mauritius emerged from the sea about 7-10 million years ago; four volcanic episodes created the land mass that we can now see. Each phase created a different layer of minerals, starting from the oldest to the most recent: 
Deep-sea drilling of the ocean floor reveals the presence of polymetallic nodules in the Indian Ocean. It is estimated that these nodules have a coverage of about 10-15 million km2, weighing about 1.5×1011 tonnes, across the whole of the Indian Ocean .
Mauritius is located in the West Indian Ocean Basin; geomorphological analyses of the seabed near Mauritius report numerous seamounts and guyots (flat based mountains), trenches and fractures . All these different structures influence the type of minerals that can possibly be found in the areas close to Mauritius.
Recently, new discoveries suggest that Mauritius may be lying on a part of an oceanic crust or microcontinent called ‘Mauritia’. The land mass broke off Madagascar during plate separation 65 million years ago but finally sunk to the bottom . Being made of continental granite, mineral content in this layer could be fascinating. Detrital zircons have already been found in the granitic rock as lava-plumes have brought minerals to the surface .
Shallow water species that have been identified include the:
To date, 8,000 sedimentary marine organisms have been documented in the Western Indian Ocean shallow waters . A comprehensive study of the marine creatures on the ocean floor is still to be made as deep sea exploration is quite difficult to undertake.
In 2011, 6 new sea creatures were discovered in vents in the South West Indian Ocean floor . More recently, oil and gas reserves have been detected near Seychelles . All these discoveries suggest that the deep ocean floor around Mauritius may be hiding a lot of amazing treasures.
