Sedimentological impacts of INDEX experiment
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)
The polymetallic nodule exploration programme (PMN) has already identified one Indian mine site in the Central Indian Basin (CIB) where deep-sea mining activities are likely to start in future. In order to assess the ...
Coexistence of pumice and manganese nodule fields-evidence for submarine silicic volcanism in the Central Indian Basin
(Pergamon, 1993)
Pumice, of various shapes and sizes, uncoated or coatEd. by ferromanganese oxides, have been recovered from deeper parts of the Central Indian Basin (CIB). The pumice field covers an area of 600,000 km sup(2), approximately ...
India's manganese nodule mine site in the Central Indian Ocean
(Current Science Association, Bangalore, India, 1996)
This commentary highlights the activities of massive exploration programme for manganese nodule deposits in the Central Indian Basin located 5 km below the ocean surface and India's claim for mine site development and ...
Technological challenges for manganese nodule mining
(Publ. and Inf. Dir., New Delhi, India, 1994)
The major technological challenges of deep-sea mining venture involve delineation of mine site and development of mining technology to bring out the minerals from extreme conditions (more than 5 km water depth, 0-3 degrees ...
Effect of benthic disturbance on geotechnical characteristics of sediments from nodule mining area in the Central Indian Basin
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)
Benthic disturbance is carried out in the Central Indian Basin for environmental impact assessment studies. Geotechnical measurements were made on sediments collected before and after disturbing the top 10-15 cm of the ...
Distribution of manganese nodules, rocks and sediments in the Central Indian Ocean Basin: Factors influencing performance of mining system
(Publ. and Inf. Dir., New Delhi, India, 1994)
Manganese nodule abundances in the Central Indian Ocean Basin (CIOB) as noted from seabed photographs (nil to 18.4 kg/m sup(2)) and grabs (nil to 21.5 kg/m sup(2)) are variable. The relative abundance varies from zero to ...
Petrogenesis of ferromanganese nodules from east of the Chagos Archipelago, Central Indian Basin, Indian Ocean
(Elsevier, 1999)
Deep-sea ferromanganese nodules occur over a large area and on many different sediment types of the Central Indian Basin, Indian Ocean. Selected samples were studied to determine their chemical and mineralogical compositions ...
Nodules size: An important factor in nodule mining?
(Int. Soc. of Offshore and Polar-Eng.(ISOPE), Colorado, USA, 1995)
A study of about 850 different sized nodules from 234 sites in the Central Indian Basin (CIB) showed a clear inverse relationship between size and grade of nodules. Among the different sized nodules, only the small (less ...
Polymetallic nodule resources of the Indian Ocean
(Offsetters, New Delhi, 1993)
The seabed resources are large and varied and considerable knowledge and technological development are required to exploit them economically. Beyond the Exclusive Economic Zone (EEZ), the deposits which are of utmost ...
Influence of bathymetry in manganese nodule pilot mine site selection: A case study from the Central Indian Basin
(Int. Soc. of Offshore and Polar-Eng.(ISOPE), Colorado, USA, 1995)
Although manganese nodules are observed in all world oceans, known reserves cannot be only criterion in future mine sites selection and sizing. Detailed and accurate depth data is another major prerequisite. With the advent ...
