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 ... -
Elemental distributions in surficial sediments and potential offshore mineral resources from the western continental margin of India. Part 2. Potential offshore mineral resources
(NIO, Goa, India, 1994)The project entitled 'Geochemistry of sediments of the continental margins of India and deep sea regions' was initiated in 1976 and since then formed an important research activity of the Institute. The main objectives of ... -
Fine particle deposition at Vainguinim tourist beach, Goa, India
(Coastal Research Foundation, 1998)Vainguinim Beach is a small and narrow pocket beach located on the rocky coast of Dona Paula Bay, at the estuarine front of the Zuari River in Goa, India. The beach has been widely used for recreation and swimming by a ... -
Heavy mineral distribution in the surficial sediments from the eastern continental margin of India and their implications on palaeoenvironment
(Indian Society of Earth Sciences, Calcutta, 1996)Heavy mineral distribution from the surficial sediments of the Eastern Continental Margin of India, between Machilipatnam and Gopalpur shows that their concentration ranges from 0.4 to 13.9%. Heavy minerals such as opaques, ... -
Heavy mineral suite in the shelf sediments off Madras coast
(Indian Geophysical Union, 1972)The heavy mineral suite of the shelf sediments of this area (12~'00': 13~'05'N and 80~'00': 80~'36'E), are characterised by a dominant group of minerals such as hornblende, augite, hypersthene, garnet and opaque minerals; ... -
Heavy Minerals in the Sediments on the Outer Continental Shelf between Vengurla and Mangalore on the West Coast of India
(Geological Society of India, 1981)Fifty-eight sediment samples from the outer continental shelf between Vengurla and Mangalore were analysed for heavy minerals consist of principally opaques, hornblende, epidote, garnet, sillimanite, hypersthene and zircon, ... -
Impact of offshore placer mining experiments (PLAMEX) on the sediment size and heavy minerals
(Current Science Association, 2009)Two offshore placer mining experiments (PLAMEX) were conducted using submersible pumps specially designed by Central Mechanical Engineering Research Institute (CMERI), Durgapur (India) at 8 m water depth in Kalbadevi Bay ... -
Magnetic Surveys of the Continental Shelf off Visakhapatnam
(Indian Association for Limnology and Oceanography, 1980)Continuous magnetic surveys over the continental shelf off Visakhapatnam reveal total magnetic field anomalies of high amplitude and short period over the inner shelf and of comparatively low amplitude with long period ... -
Morphogenetic controls on the distribution of the littoral placers along central west coast of India
(M.S. University of Baroda, Vadodara, India, 1995)The total heavy mineral concentration along the central west coast of India varies from 0.17 to 98.54 percent. A zone of higher concentration is confined to the central protion of the coastal segment between 17 degrees 59' ... -
Pre- and post-monsoonal changes in grain size and heavy minerals in the sediments from Kalbadevi Bay, Ratnagiri, west coast of India
(NISCAIR (CSIR), 2011)Sediments from the Kalbadevi Bay, Ratnagiri collected during January, May and October have been studied for processes responsible for the observed grain size variations and heavy mineral distribution. The study shows ... -
Provenance signature of pre-cambrian and mesozoic rocks in the nearshore placers of Konkan, central west coast of India
(Taylor & Francis, 2009)Heavy mineral studies of the nearshore placer deposits of the Konkan Coast reveal a dominant assemblage comprised of garnet and kyanite along with other accessory minerals like epidote, olivine and rutile. The heavy mineral ... -
Shoreline configurations control on the concentration of nearshore heavy minerals: A case study from Konkan-Maharashtra, central west coast of India
(New Academic Publishers, Delhi, 2001)The geological and geophysical exploration in the nearshore areas between 3 and 19 m water depth, in four bays viz., Wada-Vetye, Ambolgarh, Rajapur and Vijaydurg along the Konkan Coast - central west coast of India (16 ... -
Transparent heavy minerals in the coastal sediments of south Maharashtra and their significance in delineating source and environment of transportation and deposition
(Allied, India, 2005)The transparent heavy minerals from the Placer rich Sands from the coastal sediments of Southern Maharashtra (South of 16 degrees 30 minutes to 15 degrees 43 minutes N Lat) are studied mainly to understand the probable ...
