Carbonate mineralogy and faunal relationship in tropical shallow water marine sediments: Cape Comorin, India
(Elsevier, 1982)The carbonate mineralogy of Recent sediments from the western and eastern continental shelves around Cape Comorin off the southern tip of India was determined by X-ray diffraction analyses. The results show that in the ... -
Dune associated calcretes, Rhizoliths and Paleosols from the western continental shelf of India
(Geological Society of India, 1997)The calcareous deposits on the western continental shelf of India, off Bhatkal (water depths 50 to 58 m) occur as crusts, sheets, cylinders and reddish brown mudstones. The outer layers of the crusts are micrite-dominated ... -
Early Pliocene paleoceanography of the Vityaz Fracture Zone (VFZ), Central Indian Ridge
(Geological Society of China, 2007)Planktic foraminifera from the calcareous substrate of a ferromanganese crust in the Vityaz Fracture Zone (VFZ), Central Indian Ridge were studied to reconstruct the early Pliocene paleoceanography of this region. Eleven ... -
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 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 ... -
Late Quaternary Halimeda bioherms and aragonitic faecal pellet-dominated sediments on the carbonate platform of the western continental shelf of India
(Elsevier, 1994)The Fifty Fathom Flat is a drowned carbonate platform located on the outer continental shelf of western India. It unique because the carbonate depositional environment prevailed until Early Holocene in spite of its proximity ... -
Occurrence of faecal pellet-filled simple and composite burrows in cold seep carbonates: A glimpse of a complex benthic ecosystem
(Elsevier, 2011)Ichnofossils preserved in marine sedimentary records provide unique information on various activities (feeding, dwelling, excretion etc.) of benthic organisms. Here we report faecal pellet-filled tubular (simple and ... -
On the nature of the calcareous substrate of a ferromanganese crust from the Vityaz Fracture Zone, Central Indian Ridge: Inferences on palaeoceanography
(Springer, 2002)A 15-cm-thick carbonate substrate encrusted with ferromanganese oxides from the Vityaz Fracture Zone, Central Indian Ridge was analysed to reconstruct the palaeoceanography of the region. Based on the calcareous nannoplankton ... -
Preliminary geotechnical properties of deepsea sediments from the Central Indian Basin
(Int. Soc. of Offshore and Polar-Eng.(ISOPE), Colorado, USA, 1995)Geotechnical properties of the Plio-Pleistocene sediments from nodule bearing area in the Central Indian Basin have been studied to know shear strength and water content variation with depth. It reveals that surface sediments ... -
Rare earth element studies of surficial sediments from the southwestern Carlsberg Ridge, Indian Ocean
(Indian Academy of Sciences, Bangalore, India, 1995)The rare earth element (REE) contents of sixteen surficial calcareous sediments from the southwestern Carlsberg Ridge, Indian Ocean, have been determined. The total REE vary from 35 ppm to 126 ppm and are inversely related ... -
Spatial and temporal variations of carbonate content in the beach and nearshore environments off Goa, west coast of India
(NISCAIR, New Delhi, 1993)Sediment samples collected from dunes, beaches (Calangute, Baina and Colva) and nearshore environments along the coast of Goa, have been analysed for their carbonate content. The results show the presence of very high ... -
Texture, carbonate content and component composition of Mauritius beach sands, Indian Ocean
(Tirunelveli: JCSONLINE, 1988)Samples collected from beaches bordering the southern, southeastern, western and northwestern shores representing swell (windward) and non-swell (leeward) dominated environments of the island of Mauritius were studied in ...
