A tektite fragment discovered in the Central Indian Basin
(Current Science Association, 1998)
On the basis of various lines of evidence, tektites are now considered as glassy objects generated by meteorite impacts, distributed in four known strewn fields, of which, the Australasian tektite strewn field is the ...
Micrometer- and nanometer-sized platinum group nuggets in micrometeorites from deep-sea sediments of the Indian Ocean
(The Meteoritical Society, 2011)
We examined 378 micrometeorites collected from deep-sea sediments of the Indian Ocean of which 175, 180, and 23 are I-type, S-type, and G-type, respectively. Of the 175 I-type spherules, 13 contained platinum group element ...
Depth anomalies in the Arabian Basin, NW Indian Ocean
(Springer, 2008)
Unreported depth anomalies in the Arabian Basin, northwest Indian Ocean is presented previously, to provide constraints on the evolution of the oceanic lithosphere of that basin. The depth anomaly reported in this study ...
Periodic deformation of oceanic crust in the central Indian Ocean
(AGU, 1998)
New seismic reflection profiles of ~~ 5370 km, running through the Ocean Drilling Program Leg 116 sites and Deep Sea Drilling Project Sites 215 and 218, were obtained to investigate the spatial extent, timing, and nature ...
Chemistry of surface sediment along a north-south transect across the equator in the Central Indian Basin: An assessment of biogenic and detrital influences on elemental burial on the seafloor
(Elsevier, 1998)
The detailed chemistry of the surface sediment collected along a north-south transect across the equator in the Central Indian Ocean suggest that: biogenic sedimentation north of equator is dominated by carbonate ooze and ...
Geochemical implications of gabbro from the slow-spreading Northern Central Indian Ocean Ridge, Indian Ocean
(Cambridge University Press, 2011)
Gabbro samples (c. < 0.4 Ma old) dredged from close to the ‘Vityaz Megamullion’ on the slow-spreading Northern Central Indian Ridge (NCIR, 18-22 mm yr sup(-1)) include mostly olivine gabbro and Fe-Ti oxide gabbro. The ...
Drift pumice in the central Indian Ocean Basin: Geochemical evidence
(Elsevier, 2008)
Abundant white to light grey-coloured pumice without ferromanganese oxide coating occurs within the Quaternary sediments of the Central Indian Ocean Basin (CIOB). Two distinct groups of pumice are identified from their ...
