Phosphorites from the error seamount, Northern Arabian Sea
(Elsevier, 1986)
Phosphorites were dredged from the flanks of the Error Seamount, off the Somali Coast from depths of 400-460 m. These occur as dense slabs and irregular lumps associated with limestones. Polished and thin section studies ...
Geochemical evidence of terrigenous influence in deep-sea sediments upto 8°S in the Central Indian basin
(Elsevier, 1989)
Thirty-two representative deep-sea sediment samples have been studied from three manganese nodule-bearing environments in the Central Indian Basin: diatomaceous-radiolarian ooze-clay, pelagic brown clay and calcareous ooze. ...
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 ...
Clay mineral distribution in the shelf sediments off the northern part of the east coast of india
(Elsevier, 1988)
Forty-eight sediment samples from the continental shelf between Visakhapatnam and the Ganges were analysed by X-ray diffraction for the composition and distribution of clay minerals. Estuarine samples of the Hooghly are ...
Microbial origin of the phosphorites of the western continental shelf of India
(Elsevier, 1988)
Phosphatised algal nodules were recovered by dredging from the western continental shelf off Goa at depths ranging from 70 to 150 m. Energy dispersive X-ray analysis indicates that the phosphorus present in the algal nodules ...
Clay mineral distribution on the Kerala continental shelf and slope
(Geological Society of India, 1983)
Seventy-five sediment samples collected from the Kerala continental shelf and slope during the 17th and 71st Cruises of @iRV gaveshani@@ were analysed by X-ray diffraction for clay mineral cntent. The distribution of total ...
Clay minerals in the sediments around the Andaman Islands
(CSIR-NISCAIR, 1983)
Clay minerals in the eastern side of Andaman Islands consist of montmorillonite, kaolinite, illite and Fe-rich chlorites while on western side they consist of illite and Fe-poor chlorite with minor kaolinite and montmorillonite. ...
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 ...
Distribution and dispersal of clay minerals on the western continental shelf of India
(Elsevier, 1982)
Sediment samples distributed over a distance of 1700 km from the inner continental shelf of western India were analysed for their clay-mineral content by X-ray diffraction. The clay minerals present in the sediments, in ...
On the possibility of high-velocity tidal sterams as dynamic barriers to longshore sediment transport: evidence from the continental shelf off the Gulf of Kutch, India
(Elsevier, 1982)
Differences in the bathymetry, bottom topography and the abundance of mica and clay minerals on the continental shelf north and south of the Gulf of Kutch, a macrotidal bay, indicate the presence of two distinct sedimentary ...
