210Pb, 230Th, and 10Be in Central Indian Basin seamount sediments: Signatures of degassing and hydrothermal alteration of recent origin
Nath, B.N.; Borole, D.V.; Aldahan, A.; Patil, S.K.; Mascarenhas-Pereira, M.B.L.; Possnert, G.; Ericsson, T.; Ramaswamy, V.; Gupta, S.M. (American Geophysical Union, 2008)Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ... -

(Wiley, 2008)Isotopic (sup(210)Pb, sup(238)U-sup(230)Th, sup(10)Be), major and trace elements, and micromorphological and microchemical data, were used to identify recent (approx. 100 yrs) hydrothermal alteration of a greater than 200 ... -
Changing sedimentary environment during the late Quaternary: Sedimentological and isotopic evidence from the distal Bengal Fan
Kessarkar, P.M.; Rao, V.P.; Ahmad, S.M.; Patil, S.K.; AnilKumar, A.; AnilBabu, G.; Chakraborty, S.; SounderRajan, R. (Elsevier, 2005)The sediments recovered from two gravity cores of the lower and distal Bengal Fan were investigated for sedimentological properties and Sr -Nd isotopes.Each core exhibits two distinct units, the lower unit 2 and upper unit ... -
Evidence of Himalayan erosional event at approx. 0.5 Ma from a sediment core from the equatorial Indian Ocean in the vicinityof ODP Leg 116 sites
Nath, B.N.; Gupta, S.M.; Mislankar, P.G.; Rao, B.R.; Parthiban, G.; Roelandts, I.; Patil, S.K. (Elsevier, 2005)A sediment core collected from an area _100 miles south of the ODP Leg 116 (distal Bengal Fan) in the equatorial Indian Ocean was investigated for microfossils, mineralogy, mineral chemistry, magnetic susceptibility, grain ... -
Fluvial influx and weathering history of the Himalayas since Last Glacial Maxima - Isotopic, sedimentological and magnetic records from the Bay of Bengal
Chauhan, O.S.; Patil, S.K.; Suneethi, J. (Indian Academy of Sciences, 2004)From temporal variations in stable isotopes, mineral magnetism, clay minerals and granulometric parameters from a sup(14) C dated core have been used to understand weathering history and influence of climate on the terrigenous ... -
Paleoclimatic and diagenetic history of the Late Quaternary sediments in a core from the southeastern Arabian Sea: Geochemical and magnetic signals
Rao, V.P.; Kessarkar, P.M.; Thamban, M.; Patil, S.K. (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 ... -
Rock magnetic and geochemical record in a sediment core from the eastern Arabian Sea: Diagenetic and environmental implications during the late quaternary
Rao, V.P.; Kessarkar, P.M.; Patil, S.K.; Ahmad, S.M. (Elsevier, 2008)Rock magnetic concentration, grain size and mineralogy parameters together with organic carbon, calcium carbonate, redox-sensitive elements, delta sup(18) O of Globigerinoides ruber and radiocarbon dating were carried out ... -
Rock magnetic records of the sediments of the eastern Arabian Sea: Evidence for the late Quaternary climatic change
AnilKumar, K.; Rao, V.P.; Patil, S.K.; Kessarkar, P.M.; Thamban, M. (Elsevier, 2005)Rock-magnetic measurements along with grain size, acid-insoluble residue (AIR), organic carbon (OC), CaCO sub(3) and delta sup(18)O of the planktonic foraminifers of the sediments were determined for 15 gravity cores ...
