Marine mineral resources of the Central Indian Basin: Ferromanganese nodules and crusts
(Gulf Pub., Houston, USA, 1996)
The morphology, mineralogy and composition of ferromanganese nodules and crusts from the Central Indian Basin and southwestern flank of the Charlsberg Ridge have been characterized from the analyses of data and samples ...
Aeolian deposition of Arabia and Somalia sediments on the southwestern continental margin of India
(Current Science Association, Bangalore, India, 1996)
Kaolinite, smectite, illite and chlorite as major clay minerals and palygorskite and gibbsite in minor quantities have been recorded from the slope of southwestern continental margin of India. Contribution of kaolinite, ...
Australian minitektites discovered in the Indian Ocean
(Meteoritical Society, Fayetteville, USA, 1999)
Large area sampling with a box core in the Indian Ocean has led to the discovery of minitektites (> 1-3.75 mm long) and a tektite fragment (approx 1.25 mm) occuring with microtektites belonging to the Australasian tektite ...
Petrology of seamounts in the Central Indian Ocean Basin: Evidence for near-axis origin
(Springer, 1995)
Previous studies on the distribution and morphology of ancient seamount chains (>50 Ma) in the Central Indian Ocean basin (CIOB) indicated their generation from the fast spreading Southeast Indian Ridge. The petrology of ...
Relationship between size and geochemistry of polymetallic nodules from the Central Indian Ocean Basin: Significance in selection of high grade nodules
(Publ. and Inf. Dir., New Delhi, India, 1994)
Morphological, mineralogical and geochemical studies on nodules of different sizes collected from the Central Indian Ocean Basin (CIOB) show two suits of nodule formation by oxic diagenetic and hydrogenous process resulting ...
Signatures of rare-earth elements in banded corals of Kalpeni atoll-Lakshadweep archipelago in response to monsoonal variations
(NISCAIR, CSIR, 1996)
Concentrations of rare-earth elements (REE) have been determined in seasonal bands of Porites species collected from the Lakshadweep lagoon. Total REE (REE) are very low (less than 3 ppm) in these corals. Seasonal variations ...
Impact microcraters on an Australasian microtektite
(Meteoritical Society, Fayetteville, USA, 1996)
Microcraters attributable to impact have been discovered on an Australasian microtektite from a core in the Central Indian Basin. The craters resemble lunar microcraters and those generated during impact experiments. The ...
Coexistence of pumice and manganese nodule fields-evidence for submarine silicic volcanism in the Central Indian Basin
(Pergamon, 1993)
Pumice, of various shapes and sizes, uncoated or coatEd. by ferromanganese oxides, have been recovered from deeper parts of the Central Indian Basin (CIB). The pumice field covers an area of 600,000 km sup(2), approximately ...
Ferrobasalts from the Central Indian Ocean Basin
(Springer, 1999)
The occurrence of ferrobasalts recovered from the Central Indian Ocean Basin crust generated at the Southeast Indian Ridge during a phase of moderate to fast spreading accretion (approx 110-190 mm/yr, full rate) is reported. ...
Phosphorite concretions in a sediment core from a bathymetric high off Goa, western continental margin of India
(Current Science Association, Bangalore, India, 1996)
A sediment core collected from a bathymetric high off Goa on the western continental margin of India, has yielded phosphorite concretions with an average Pd2O5 content of 32.75%, the P2O5 concentrations being highest ever ...
