Authigenic Gypsum in a Deep Sea Core from Southeastern Arabian Sea
(Geological Society of India, 1980)
Authigenic gypsum has been encountered in a deep sea core RC9-157 from the southeastern Arabian Sea at a depth of 4111 m which is a zone of lysocline. The formation of gypsum in the deep sea region is attributed to the ...
Foraminifera from the Deep Lake Terraces, Vestfold Hills, Antarctica
(Cushman Foundation for Foraminiferal Research, 1980)
Fourteen species of planktonic and forty-two species of benthonic foraminifera are identified from two transects of terraces near Deep Lake in the Vestfold Hills, Antarctica. All the planktonic and a few of the benthonic ...
Foraminiferal Constituent in Marine Sediments - A Parameter in some Coastal Engineering Problems
(Indian Association for Limnology and Oceanography, 1980)
Foraminifera, among other microorganisms, form a major constituent of marine sediments and their composition is directly related to the nature of the substrate in which they are entombed. Past and the present data indicate ...
Mineralogy of polymetallic nodules and associated sediments from the Central Indian Ocean Basin
(Elsevier, 1987)
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 ...
Petrography of basalts from the Carlsberg ridge
(CSIR-NISCAIR, 1989)
Petrographic characteristics of basalts collected from a segment of the Carlsberg Ridge (lat. 3 degrees 35'N to 3 degrees 41'N; long. 64 degrees 05'E to 64 degrees 09'E) show typical pillow lava zonations with variable ...
A petrographic study of Precambrian quartzites from Goa coast
(Indian Association for Limnology and Oceanography, 1980)
A petrographic and heavy minerals study of quartzites along the Goa Coast, India has been undertaken to decipher their sediment history. The quartzite outcrops exhibit well preserved primary sedimentary structures like ...
Frequency distribution of foraminifera off Trivandrum, west coast of India
(CSIR-NISCAIR, 1985)
Fifty two species belonging to 31 genera of recent foraminifera have been identified from sediment samples collected from the inshore waters. Based on relative abundance of species, it is observed that along the coast, the ...
