Difficulty: Very hardState Economy, Agriculture, and Natural Resources

With reference to the geological distribution of mineral resources and industrial belts in Jharkhand, consider the following statements:

1. The Singhbhum Shear Zone is a major thrust belt known for significant reserves of copper, uranium, and apatite.
2. The Kodarma-Giridih region forms the principal belt for high-grade pegmatitic muscovite mica deposits.
3. The coalfields of the Damodar Valley basin, such as Jharia and Bokaro, are primarily hosted within Gondwana sedimentary formations.

Which of the statements given above are correct?

  1. 1, 2, and 3Answer
  2. B
    1 and 2 only
  3. C
    2 and 3 only
  4. D
    1 and 3 only

Answer

All three statements (1, 2, and 3) are correct.
The statement option asserting that 1, 2, and 3 are all correct is accurate because all three statements correctly describe the mineral geography of Jharkhand: the Singhbhum shear zone contains copper-uranium deposits, Kodarma-Giridih is the primary muscovite mica belt, and the Damodar valley coalfields belong to Gondwana formations.

Step-by-Step Solution

1
Evaluate Statement 1 regarding the Singhbhum Shear Zone
Statement 1 is correct. The copper belt thrust zone in Singhbhum contains major deposits of copper, uranium (e.g., Jaduguda), and apatite-magnetite rocks.
Geological survey data confirms the mineralization along the Precambrian Singhbhum Shear Zone.
2
Evaluate Statement 2 regarding mica resources in Kodarma-Giridih
Statement 2 is correct. Kodarma and Giridih districts are famous globally and nationally for high-quality ruby muscovite mica hosted in pegmatites.
The mica belt stretches across Kodarma, Giridih, and Hazaribagh.
3
Evaluate Statement 3 regarding Damodar Valley coalfields
Statement 3 is correct. Prime metallurgical coking coal and non-coking coal of Jharia and Bokaro are part of the Barakar and Karharbari formations within the Lower Gondwana sequence.
Major Indian coal seams of peninsular river basins belong to the Gondwana system.
