Our changing coastlines
(CSIR-NISCAIR, 1989)
Our coastlines keep alive the sense of continuing creation and of the relentless drive of life In recent years, much has been done both to understand the processes that underlie their creation and to exploit their environment ...
Mineralogy of the carbonate sediments - western continental shelf of India
(Elsevier, 1981)
An X-ray diffraction study of forty-six sediment samples and three oolitic limestone samples from the western continental shelf of India shows that aragonite is the dominant carbonate mineral (99% maximum), followed by ...
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 ...
Slumping on the western continental margin of India
(Asociacion Argentina de Geofisicos y Geodestas, 2001)
A short gravity core from the Western Continental Margin of India has been examined to understand the nature and characteristics of slumping in the area. The present study and also the earlier studies revealed that the ...
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 ...
Sediment movement on the continental shelf off Bombay, India
(Elsevier, 1994)
Daily beach profiles and littoral environmental observations off Baga, Calangute and Miramar beaches during November-December 1999
(Goa: NIO, 2002)
This report presents the results of the field observations and theoretical studies on the coastal processes at Baga, Calangute and Miramar beaches along the North Goa coast, India. The field observations undertaken for a ...
Morphological variations in the polymetallic nodules from selected stations in the Central Indian Ocean
(Springer, 1987)
Polymetallic nodules from the Central Indian Ocean largely range in size from 2 to 6 cm. The smaller nodules (4 cm) are subspheroidal to spheroidal in shape and with the increase in size, nodules become more discoidal and ...
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 ...
