Question

Difficulty: Very hardMineral and Energy Resources of India

Match the major mineral mining deposits in List-I with their corresponding primary mineral resource in List-II, based on the spatial distribution of mineral resources in India:

  • Degana (Nagaur, Rajasthan)Tungsten (Wolframite)
  • Ambadungar (Chhota Udepur, Gujarat)Fluorite (Fluorspar) and Rare Earth Minerals
  • Hutti (Raichur, Karnataka)Primary Lode Gold
  • Chavara (Kollam, Kerala)Heavy Mineral Placer Sands (Ilmenite, Rutile, Monazite)

Answer

Degana matches with Tungsten (Wolframite); Ambadungar matches with Fluorite and Rare Earth Minerals; Hutti matches with Primary Lode Gold; and Chavara matches with Heavy Mineral Placer Sands.
The pairing correctly aligns each distinct geological region with its predominant mineral resource: Degana is known for tungsten (wolframite), Ambadungar for carbonatite-hosted fluorite and rare earth elements, Hutti for primary lode gold within Dharwar greenstone schists, and Chavara for coastal placer deposits of heavy mineral sands containing ilmenite and monazite.

Step-by-Step Solution

1
Identify the primary mineral mined at Degana in Nagaur, Rajasthan.
Degana is historically and geologically known as India's main tungsten (wolframite) deposit site.
Tungsten mineralization occurs in quartz veins intrusive into the Delhi Supergroup rocks at Degana.
2
Determine the resource associated with Ambadungar in Gujarat.
Ambadungar hosts carbonatite-alkaline complexes containing world-class fluorite deposits alongside rare earth minerals.
Fluorspar mining by GMDC at Ambadungar is a key industrial non-metallic mineral activity in the region.
3
Locate the primary economic activity of Hutti in Karnataka.
Hutti is an operational center for underground primary gold mining operated by Hutti Gold Mines Limited.
It is located in the Archaean schist belts of the Dharwar Craton.
4
Analyze the coastal deposit characteristics at Chavara in Kerala.
Chavara beach sands are rich in heavy minerals including ilmenite, rutile, zircon, sillimanite, and monazite.
Wave action and coastal currents concentrate high-density placer minerals derived from the Western Ghats crystalline rocks.
