Abstract Rare Earth Element and Yttrium (REY)-rich deep sea sediments have been
estimated to be a highly important potential resource. However, the main material sources …

Metalliferous sediments are the most widespread hydrothermal object in the World Ocean.
Their fields are halos of dispersion of submarine hydrothermal mineral forming systems, and …

The Indian Ocean Nodule Field (IONF) is significant from several points of view. Roughly
bordered by 10° S to 16° 30′ S and 72° E to 80° E and located within the Central Indian …

Volcanic glass and pumice found in siliceous abyssal sediments of the Central Indian Basin,
south of the Equator, have previously been assigned various origins including intra-basin …

As a potential mineral resource, the clay minerals enriched in rare earth elements including
yttrium (REY) in the deep sea have been attracting great attention. However, the enrichment …

We have investigated the sediments from a site where a newly discovered submarine
hydrothermal alteration of recent origin is located to identify the source components and …

The Indian Ocean Nodule Field: Geology and Resource Potential, Second Edition, provides
a view of the most recent studies along with classical theories starting from the 1960s. New …

We report the occurrences of magnetite-rich spherules, Ti-rich particles and possibly
nontronite recovered at 19° S and 76° E from the pelagic clay in the Central Indian Ocean …

The morphotectonic features of the Central Indian Ocean Basin (CIOB) provide information
regarding the development of the basin. Multibeam mapping of the CIOB reveals presence …

Volcanic glasses associated with pumice, micronodules and palagonite like lithic fragments
were recovered from a volcanic terrain in a fracture zone defined as Rodriguez Triple …
