In the mineral and energy resources sector of Tamil Nadu, the extensive tertiary sedimentary deposits of lignite that fuel the Neyveli thermal power generation complex are primarily concentrated in which district?

  1. A
    Salem district
  2. Cuddalore districtAnswer
  3. C
    Tiruchirappalli district
  4. D
    Ramanathapuram district

Answer

Cuddalore district is the primary location of the Neyveli lignite deposits that power Tamil Nadu's major thermal energy sector.
Cuddalore district encompasses the Neyveli basin, which contains the largest proven reserves of tertiary lignite in India. These deposits form the foundation of open-cast mining operations that feed multiple pithead thermal power stations run by NLC India Limited.

Step-by-Step Solution

1
Identify the target resource and key industrial facility
Tertiary brown coal (lignite) mined by NLC India Limited for pithead thermal power generation.
Establishing the precise mineral commodity and its commercial application narrows down the geological formation.
2
Map the resource to its state administrative geography
The Neyveli mining basin is situated in Cuddalore district in north-central coastal Tamil Nadu.
Connecting the geological deposit to state administrative boundaries identifies the correct district.
3
Distinguish from other mineral zones of the state
Salem contains metallic and industrial minerals (magnesite, iron ore), Tiruchirappalli has non-metallic gypsum/limestone, and Ramanathapuram has hydrocarbon reserves.
Eliminates distracting mineral centers by their distinct geologic profiles.
