Solution
The correct option is C Thorium
Answer: The correct answer is option (c) – Thorium
- The Monazite sands of Kerala are rich in Thorium.
- It has been suggested as a replacement for uranium as nuclear fuel in nuclear reactors, and several thorium reactors have been built.
- Uranium and Thorium, which are available in Jharkhand and the Aravalli ranges of Rajasthan, are used for generating atomic or nuclear power.
Coal
- In India coal was mainly formed over 2 main geological ages. Some were formed about 55 million years ago are the tertiary deposits, some were formed during the Gondwana period, around 200 million years ago.
- West Bengal – Jharkhand (Damodar Valley) is the major source of Gondwana coal in India, these are metallurgical coal.
- Bokaro, Raniganj, Jharia are the important coalfields.
- Wardha, Son, Mahanadi and Godavari valleys are the other important locations for coal deposits in India.
- Nagaland, Arunachal Pradesh, Assam, Meghalaya are the North Eastern states where tertiary coals are located.
- Thermal power stations and heavy industries are located near coalfields.
- The most abundant fossil fuel in India is Coal.
- Major part of India’s energy needs are met through coal.
- By using coal as a fuel, power is generated in thermal power stations, and this power is supplied to meet the domestic power requirements and as well as power requirements of industries.
Oil
- Naharkatiya,Moran-Hugrijan, and Digboi are the important oil fields in the state of Assam. The oldest oil producing state in India is Assam.
- In Gujarat, the most important oil field is located in Ankleshwar.
- In India after coal, mineral oil or Petroleum is the next major energy source.
- Oil is used as raw material in many manufacturing industries, lubricants for machinery, used for lighting and heat.
- Petroleum refineries act as an important industry for many chemical industries, fertiliser and synthetic textile industries.
- Petroleum is found in fault traps between non-porous rocks and porous rocks.
- About 16 per cent of India’s petroleum production is from Assam, 18 per cent from Gujarat, and 63 percent of India’s petroleum production is from Mumbai High.
- In the rock formations belonging to tertiary age, most of the petroleum occurrences in India are associated with fault traps and anticlines.
- Petroleum occurs where oil is trapped in the crest of the upfold, in regions of domes or anticlines and folding.
