Paired measurements of foraminiferal delta 18 O and Mg/Ca ratios of Indian monsoons reconstructed from Holocene to Last Glacial record
(Geological Society of China, 2011)The effect of seasonally reversing monsoons in the northern Indian Ocean is to impart significant changes in surface salinity (SS). Here, we report SS changes during the last 32 kyr in the Lakshadweep Sea (southeastern ... -

(CSIR-NISCAIR, 2014)Important archaeological sites of our investigation include Dwarka, Bet Dwarka, Kindar Kheda, Pindara, Somnath and sites in Gulf of Khambhat and evidences recorded from these sites include stone anchors, remains of jetties ... -
Palaeoceanographic conditions during the formation of ferromanganese crust from the Afanasiy Nikitin seamount, north central Indian Ocean: geochemical evidence
(Elsevier, 1997)A ferromanganese crust dredged from the summit of the Afanasiy-Nikitin seamount in the composed of fresh-water phreatic calcite cement, Terebratulinae casts, rounded and ferruginised basalt clasts and weathered coralline ... -
Palaeoceanographic implications of abundance and mean proloculus diameter of benthic foraminiferal species Epistominella exigua in sub-surface sediments from distal Bay of Bengal fan
(Indian Academy of Sciences, 2005)Temporal variation in abundance and mean proloculus diameter of the benthic foraminiferal species Epistominella exigua has been reconstructed over the last approx. 50,000 yr BP, from a core collected from the distal Bay ... -

Palaeoclimatic significance of gypsum pseudomorphs in the inner shelf sediments off Machalipatnam bay
(Geological Society of India, 1988)Pseudo-gypsum crystals have been found in the coarse fraction of the sediments from the inner continental shelf off Machilipatnam Bay. They range in size from 3 to 7 mm are elongate and lenticular in shape. Bassanite and ... -
Palaeoecology of Fossil Diatoms (The Thermometers of Salinity) of Lake Bonneville, Utah, USA
(1980)Kolbe (1927) described diatoms as indicators of salinity hence the fossil diatoms can yield paleoecological information considerable importance to the geologist regarding the environment in which their enclosing sediments ... -
Palaeogene hardgrounds and associated intraclast lag deposits as the substrates of ferromanganese crusts and nuclei of nodules: Inferences of abyssal current in the Central Indian Ocean Basin
(Palaeontological Society of India, 1995)The Palaeogene substrates of ferromanganese crusts and nuclei of nodules collected from the Central Indian Basin chiefly consist of incipient to younger pelagic hard grounds and associated intraclast lag deposits. The ... -

Paleocene on-spreading-axis hotspot volcanism along the Ninetyeast Ridge: An interaction between the Kerguelen hotspot and the Wharton spreading center
(Indian Academy of Sciences, Bangalore, India, 1999)Investigations of three plausible tectonic settings of the Kerguelen hotspot relative to the Wharton spreading center evoke the on-spreading-axis hotspot volcanism of Paleocene (60-54 Ma) age along the Ninetyeast Ridge. ... -
Paleoclimatic and diagenetic history of the Late Quaternary sediments in a core from the southeastern Arabian Sea: Geochemical and magnetic signals
(The Oceanographic Society of Japan, 2010)Geochemical and rock-magnetic investigations were carried out on a sediment core collected from the SE Arabian Sea at 1420 m depth in oxygenated waters below the present-day oxygen minimum zone. The top 250 cm of the core ... -
Paleodepositional and Hydrocarbon Source-Rock Characteristics of the Sonari Succession (Paleocene), Barmer Basin, NW India: Implications from Petrography and Geochemistry
(Springer, 2022)Lignite deposits, associated with Akli Formation (Paleocene), from the Sonari mine of Barmer Basin, Rajasthan, were investigated by applying organic petrography, palynofacies, and geochemistry in order to understand the ... -
