Which one of the following coalfields belongs to lignite-type coal deposit?

Correct option is C

1. Makum, Assam (Lignite):
· Makum coalfield in Assam is known for its lignite deposits. Lignite, also called brown coal, is a lower-rank coal with high moisture and low carbon content. It is often found in areas with recent sedimentary deposits.
2. Other Coalfields (Non-Lignite):
· Raniganj, West Bengal: Produces high-grade bituminous coal, suitable for industrial use.
· Singrauli, Madhya Pradesh: Supplies bituminous coal primarily for thermal power plants.
· Talcher, Odisha: Produces a mix of bituminous and sub-bituminous coal used for power generation.
Key Points: 1. Coal Classification:
· Peat → Lignite → Bituminous → Anthracite (in order of increasing carbon content and energy efficiency).
2. Major Lignite Deposits in India:
· Neyveli (Tamil Nadu) and Gujarat are major producers.
3. Makum Coalfield Features:
· Located in the Tinsukia district of Assam.
· Contains lignite and bituminous coal deposits with high sulfur content.
· Important for regional industrial and power-generation purposes.
4. Applications of Lignite:
· Thermal power generation.
· Synthetic natural gas and chemical feedstocks.
Additional Knowledge: 1. Raniganj Coalfield:
· Oldest coalfield in India, producing high-quality bituminous coal, located in West Bengal.
2. Singrauli Coalfield:
· Spans Madhya Pradesh and Uttar Pradesh, with major bituminous coal reserves fueling India's energy requirements.
3. Talcher Coalfield:
· Located in Odisha, producing sub-bituminous and bituminous coal widely used in power plants.
4. Lignite in Assam:
· Found in Makum and adjoining areas, contributing to regional energy needs.
