Geochemical variability of MORBs along slow to intermediate spreading Carlsberg-Central Indian Ridge, Indian Ocean
(Elsevier, 2013)ICP-MS trace element data from the Carlsberg Ridge MORBs from two different locations is presented. Using this data the intra-ridge geochemical variations of the Carlsberg Ridge - Central Indian Ridge MORBs is reassessed. ... -
Geochemical, mineralogical, and Sr-Nd isotopic compositions of ferromanganese encrustations from Central Indian Ridge at 06�38.5-S
(John Wiley & Sons, 2018)Mineralogical, geochemical, and isotopic (Sr and Nd) studies of 14 ferromanganese encrustations on basaltic substrates from Central Indian Ridge at 06�38.5-S indicate that except for two (NC3 and NC4), the samples are ... -
Geochemistry and granulometry as indicators of paleoclimate, weathering, and provenance of sediments for the past 1,00,000 years in the eastern Arabian Sea
(Elsevier, 2022)Geochemical and granulometric investigation of a 408 cm long sediment core raised from the Eastern Arabian Sea was carried out to decipher the climate, weathering, dust flux and provenance of sediments during the past 100 ... -
Geochemistry of aerodynamically distorted Australasian microtektites: Implications for ejecta on Mars and Venus
(Springer, 2021)We report microtektites recovered from a large area of the deep seafloor (Central Indian Ocean) that appear to have undergone aerodynamic distortion during re-entry into the atmosphere. Considering the geographic locations, ... -
Geochemistry of calcareous sediments from the SW Carlsberg Ridge: Evidence for deeper carbonate compensation depth
(NISCAIR, CSIR, 1995)Concentration of Mn, Fe, Ni, Co, Zn, Ca, Mg, K, Al, Si, Ti, P and CaCO sub(3) show wide range for the calcareous sediments from SW Carlsberg Ridge (CR). Compared with the average pelagic clays, the CR sediments are enriched ... -

Geochemistry of deep-sea sediment cores from the Central Indian Ocean Basin
(NISCAIR, New Delhi, 1993)Four sediment cores from the Central Indian Ocean Basin (CIOB) were studied to characterise the coarse fraction (less than 63 mu), transition metal and major oxide contents. Transition metals (Mn, Cu, Ni, Zn) show enrichment ... -
Geochemistry of ferromanganese micronodules and associated Mn and trace metals diagenesis at high terrigenous depositional site of middle fan region, Bay of Bengal
(Elsevier, 2003)The influence of sedimentation on the morphology, growth and geochemistry of the micronodules, and on Mn enrichment in the sediments of the Bay of Bengal has been evaluated. Mn accumulation is 307-219 mg cm u2 kyr u-1 in ... -
Geochemistry of ferromanganese nodule-sediment pairs from central Indian Ocean Basin
(Elsevier, 2011)Fourteen ferromanganese nodule-sediment pairs from different sedimentary environments such as siliceous ooze (11), calcareous ooze (two) and red clay (one) from Central Indian Ocean Basin (CIOB) were analysed for major, ... -
Geochemistry of ferromanganese nodules from different areas in North Equatorial Pacific

Geochemistry of metals in grain size fractionated sediments from estuarine and coastal regions along Mumbai: A baseline information
(CSIR-NISCPR, New Delhi, 2023)Differential metal accumulation in fractionated sediments within highly urbanized land-sea ecosystems is significant, often due to an imbalance between sluggish hydrodynamics and over dumping of contaminants. Here, an ... -
Geochemistry of organic matter in the ocean. By E.A. Romankevich

Geochemistry of polymetallic nodules from the Central Indian Ocean basin
(Elsevier, 1992)Polymetallic nodules dredged at fourteen stations between 12 degrees-15 degrees S and 76 degrees-80 degrees E in the Central Indian Ocean Basin (CIOB) display wide variations in shape, size, texture, mineral phases and ... -
Geochemistry of Sediment cores of the Western Equatorial Indian Ocean
(Indian Association for Limnology and Oceanography, 1983)Geochemical investigations including partition analysis have been carried out on nine sediment cores from the western equatorial Indian Ocean. The results show that a core from the Arabian Sea exhibits a greater terrigenous ... -
Geochemistry of sediments
(Oxford and IBH, New Delhi, 2001)Considering the potential of elemental data in marine sediments as diagnostic tools of various geological and oceanographic processes, sediment geochemical data from the Indian Ocean region has been reviewed in this article. ... -
Geochemistry of sediments in contact with oxygen minimum zone of the eastern Arabian Sea: Proxy for palaeo-studies
(Springer, 2022)The Arabian Sea encompasses oxygen minimum zone with denitrifying conditions. For the present study, sediments were collected across three transects off Goa transect (GT), Mangalore transect (MT) and Kochi transect (KT) ... -
Geochemistry of sediments of the eastern continental shelf of India
(Indian Association for Limnology and Oceanography, 1985)The bulk and partition geochemistry of Al, Fe, Ti, Mn, Zn, and Cu have been investigated in sediments of the eastern continental shelf of India. The results show that (1) the bulk geochemistry varies from one shelf unit ... -
Geochemistry of surficial sediments along the central southwest coast of India - Seasonal changes in regional distribution
(Coastal Education and Reserch Foundation, 2003)The coastal sediments (129 samples) of central- southwest coast of India, in and around Cochin, the second biggest industrial city along the west coast of India, were analyzed for their textural and geochemical fractions ... -
