Clay mineral distribution on tropical shelf: an example from the western shelf of India
(Indian Association of Sedimentology, 1989)Seventy-five sediment samples collected from the Kerala continental shelf and slope during the 17th and 71st Cruises of RV Gaveshani were analysed by X-ray diffraction for clay mineral content. The distribution of total ... -
Clay mineralogy of the mud banks of Cochin
(Current Science Association, 1968)The mineralogy of the sediments constituting the mud banks formed off Cochin, Kerala, India was studied. The clay mineral composition was used as a means of understanding the nature and source of origin of the muds. Fine ... -
Distribution and composition of verdine and glaucony facies from the sediments of the western continental margin of India
(Society for Sedimentary Geology, Tulsa, USA, 2000)Investigations on green grains from sediments of the western continental margin of India, between Ratnagiri and Cape Comorin, (water depth 37-330 m) indicate the presence of verdine and glaucony facies. Verdine facies ... -
Isolation and x-ray structure of deoxycholic acid from the sponge Ircinia sp.
(Natural Product Communications Inc., 2011)Ethyl acetate extract of the sponge Ircinia sp., collected by SCUBA divers off the coast of southern India, contained a cholest-based sterol of insignificant antimicrobial activity, with one carboxylic acid side chain (3 ... -
Nature, distribution and origin of clay minerals in grain size fractions of sediments from manganese nodule field, Central Indian Ocean Basin
(CSIR-NISCAIR, 1988)DT, IR and X-ray diffraction analyses have been carried out on 3 grain size fractions (1, 1-2 and 2-4 mu m) of sediments from the Central Indian Ocean Basin. Results indicate that there are 2 smectite minerals (montmorillonite ... -
Sediment boron and its relation to sediment properties in a tropical estuary
(Indian Association for Limnology and Oceanography, 1988)Boron in the sediments of Mandovi estuary varied from 8.0 to 258.0 ppm with an average of 118 ppm. It showed an inverse relation to the texture of sediments and was found to be concentrated in silt and clay fraction with ...
