A project on various minerals found in odisha
Answers
Answer:
Orissa has a lion share of the Country's mineral reserves. The chromite, nickel, bauxite, iron ore and coal resources of the state respectively stand at a staggering 83, 92, 55, 38 and 26 percent of India's total reserves. ... Many cement and sponge iron plants have been set up.
Explanation:
MINERALS OF ODISHA
Odisha topped among all the states as it contributed above 10% to total mineral production in the country.
The value of principal minerals produced remained at Rs. 22567.67 crore, an increase of 31.64% over the previous year period.
The value of minor minerals remained Rs. 85.68 crores.
Coal, bauxite, chromite, iron & manganese ore and limestone almost contributed 99% of the total value of mineral production.
The state is gifted with large reserves of bauxite, chinaclay, chromite, coal, dolomite, fireclay, graphite, gemstones, iron ore, limestone, manganese ore, mineral sand, nickel ore, pyrophylite and quartz.
The rich mineral wealth of the state is attributed to its favourable Geological condition & setup.
Situated on the eastern fringe of the peninsular India, Orissa has about 72.5%of the area occupied by Precambrian metamorphic rocks (of Archaean and Proterozoic age) which hosts the majority of the minerals.
The Gondwanas hosting the coal resources occur over about 8% of the landmass.
The tertiary and quaternary formations, occupying rest of the area, provide avenues for aluminous/ nickeliferous laterite and heavy minerals (in beach sand).
The Archaean rocks in northern Orissa include the Supracrustal belts of meta sedimentary rocks including Iron Ore Super Group having deposits of iron, manganese, gold and base metals. These are also represented by the gneisses, granite, migmatite (Singhbhum, Bonai and Mayurbhanj Plutons) and mafic/ ultramafic intrusives. These intrusive are linked with the chromite, titaniferous vanadiferous magnetite and PGM.
The Bastar cratonic complex of Archaean age in the Western Orissa includes gneisses, granite, migmatite and Strontium‐Tantalum‐Niobium bearing pegmatites.
Proterozoic rocks in the western Orissa exhibit platformal sedimentary formations and associated limestone deposits.
In north‐western Orissa they contain meta-sediments of low to medium metamorphic grade classified as the Gangpur Group, which host manganese, limestone and Lead‐Zinc deposits.
In central and southern Orissa, the Proterozoics are represented by the Eastern ghats granulite belt comprising of khondalite, charnockite, migmatite, anorthosite and alkaline rocks accounting for the mineralization of bauxite, manganese, graphite and gemstones.
The Mesozoic rocks of Gondwana Super Group host the major coal resources of the state. Formations of Cenozoic age occupy the eastern coastal plains in form of alluvial sediments, ash beds and low level laterite, providing avenues for occurrence of beach sand minerals and building materials. The deltaic fans extending into offshore regions play hosts for oil and gas.
