Match List – I with List – II and select the correct answer using the codes given below the lists : List – I (Coal Fields) A) Talchir B) Karnapura C) Singroli D) Singreni List II (Located) 1) Damodar Valley 2) Son Valley 3) Godavari Valley 4) Mahanadi Valley Codes:

The correct match is A-4, B-1, C-2, D-3, so option A is right. The question's 'Karnapura' is the Karanpura coalfield.

• Talchir (A to 4, Mahanadi Valley): Talchir lies in Odisha's Brahmani-Mahanadi basin, and it is the source of the Talchir (Permian) coal measures that give the name to the Talchir formation.
• Karanpura (B to 1, Damodar Valley): It lies in Jharkhand, in the Damodar basin, and is a major source of coking coal. Jharkhand was carved out of Bihar in 2000, so older texts may still place it in Bihar.
• Singrauli (C to 2, Son Valley): It spans Madhya Pradesh and Uttar Pradesh (Sonbhadra), and drains into the Son. It is a major thermal coal belt.
• Singareni (D to 3, Godavari Valley): It lies in Telangana, in the Godavari basin, and is the chief coal producer of South India, run by SCCL.

The core concept is the Gondwana coalfields and their river-valley classification. For Mains, link this to coal reserves, the coking-coal shortage, and the distribution of thermal power plants near pitheads.

Trap: Candidates often swap Karanpura and Singrauli because both sit near the Damodar and Son systems. Remember that Karanpura is in the Damodar and Singrauli is in the Son.
