Mineral chemistry and alteration characteristics of spinel in serpentinised peridotites from the northern central Indian Ridge
(Geological Society of India, 2015)
Serpentinites (frequently cross cut by gabbroic dikelet), collected from Northern Central Indian Ridge (NCIR), Indian Ocean, contain both Cr-rich (Group I) and Cr-poor (Group II) variety of spinel. Based on mineralogy they ...
Major and trace element geochemistry of S-type cosmic spherules
(The Meteoritical society, U.S., 2016)
Micrometeorites that pass through the Earth's atmosphere undergo changes in their chemical compositions, thereby making it difficult to understand if they are sourced from the matrix, chondrules, or calcium–aluminum-rich ...
Geologic implications of gas hydrates in the offshore of India: Results of the National Gas Hydrate Program Expedition 01
(Elsevier, 2014)
The Indian National Gas Hydrate Program Expedition 01 (NGHP-01) is designed to study the occurrence of gas hydrate along the passive continental margin of the Indian Peninsula and in the Andaman convergent margin, with ...
The abrupt onset of the modern South Asian monsoon winds
(Macmillan Publishers Limited, 2016)
The South Asian Monson (SAM) is one of the most intense climatic elements yet its initiation and variations are not well established. Dating the deposits of SAM wind-driven currents in IODP cores from the Maldives yields ...
Microbial iron reduction and methane oxidation in subsurface sediments of the Arabian Sea
(Elsevier, 2015)
Arabian Sea is one of the most productive regions of the world's ocean with seasonal upwelling and a characteristic oxygen minimum zone. It receives a continuous input of windborne iron-rich dust which possibly stimulates ...
Sedimentary pigments and nature of organic matter within the oxygen minimum zone (OMZ) of the Eastern Arabian Sea (Indian margin)
(Elsevier, 2016)
Sedimentary pigments, carbon and nitrogen content and their stable isotopes were studied in three short cores collected from the oxygen minimum zone (OMZ) of the Eastern Arabian Sea (EAS). Nine pigments including chlorophyll ...
Linkage between speciation of Cd in mangrove sediment and its bioaccumulation in total soft tissue of oyster from the west coast of India
(Elsevier, 2016)
This study established a mechanistic linkage between Cd speciation and bioavailability in mangrove system from the west coast of India. High bioaccumulation of Cd was found in the oyster (Crassostrea sp.) even at low Cd ...
Phosphorous fractionation in mangrove sediments of Kerala, south west coast of India: the relative importance of inorganic and organic phosphorous fractions
(Springer, 2016)
The study of phosphorous dynamics in mangrove ecosystems of the northern Kerala coast aims to delineate its relationships with other biogeochemical parameters. Our intension is to check the validity of the hypothesis that ...
Partitioning of metals in different binding phases of tropical estuarine sediments: importance of metal chemistry
(Springer, 2016)
Distribution of metals in different binding phases of estuarine sediments provides chemically significant description of metal–sediment interactions. This study describes the influences of ligand field stabilization energy ...
A comparison of Mg/Ca ratios in Globigerinoides ruber (white): sensu stricto versus a mixture of genotypes
(Geological Society of India, 2016)
Mg/Ca ratios were measured in core AAS9/21 from the eastern Arabian Sea (EAS), on two sets of planktonic foraminifera, one with a mixture of Globigerinoides ruber genotypes (sensu stricto and sensu lato) and the second ...
