Mineralogy of polymetallic nodules and associated sediments from the Central Indian Ocean Basin
Todorokite is the dominant mineral phase in the nodules of the northern Central Indian Ocean Basin. These nodules are characterised by a rough surface texture, are relatively rich in Mn, Cu and Ni, and are associated with ...
Rock magnetic records of the sediments of the eastern Arabian Sea: Evidence for the late Quaternary climatic change
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 ...
Lime muds and their genesis off-Northwestern India during the late Quaternary
(Indian Academy of Sciences, 2012)
Two sediment types were found in five gravity cores collected from water depths between 56 m and 121 m along the northwestern continental margin of India. lime mud was abundant in the lower section while siliciclastic ...
Clay minerals as palaeomonsoon proxies: Evaluation and relevance to the late Quaternary records from SE Arabian Sea
(NCAOR, Goa, 2005)
Palaeoclimatic studies are largely dependent on the quality of records and a prudent use of environmental proxy indicators. In this study, the factors affecting the detrital clay minerals in marine environment and their ...
Indian summer monsoon variability during the Holocene as recorded in sediments of the Arabian Sea: Timing and implications
Indian monsoon precipitation fluctuated significantly during the Holocene and a reliable reconstruction of the timing of the events and their implications is of great benefit to our understanding of the effect and response ...
Controls on organic carbon distribution in sediments from the eastern Arabian Sea margin
Sediment cores from the upper continental slope of the eastern Arabian Sea have high organic carbon (OC), CaCO sub(3), and sand content at the top. The values decrease with increasing depth in the Holocene and Upper ...
