Description Marine minerals have been center of attraction to mankind since ancient times. The technological advances in the recent years show that the retrieval of underwater minerals from deep-sea can no longer be a dream. Marine minerals are terrigenous (placers), biogenous (ooze, limestone) or chemogenous (phosphorites and polymetallic nodules) type. In recent years, hydrothermal deposits, cobalt crust and methane gas hydrates are considered as frontier resources. Their distribution depends upon proximity to the source, supply rate, sediment type and seabed topography. Indian Ocean is second largest and least explored for nonrenewable resources. Compared to deep-sea, relatively better knowledge is available for the near shore deposits. A concise account of present status of nonrenewable marine minerals from the near shore and deep-sea in the Indian Ocean is presented here.
