Difficulty: HardState Economy, Agriculture, and Natural Resources

Regarding the economic geography, mineral resource distribution, and agricultural features of Karnataka, which of the following statements are correct?

  1. The Sandur hill range located in the Vijayanagara/Ballari region contains rich reserves of high-grade hematite iron ore and manganese.Answer
  2. The Hutti Gold Mines located in Raichur district represent the primary active underground gold mining operation in India.Answer
  3. C
    Laterite soils dominate the Northern Dry Zone of Karnataka, providing the ideal medium for rainfed deep-rooted black cotton soil crops.
  4. D
    Karnataka accounts for the largest share of India's onshore crude petroleum reserves, concentrated mainly along the Malnad plateau.

Answer

The statements highlighting that the Sandur hill range contains high-grade hematite iron ore and manganese, and that Hutti Gold Mines in Raichur district is India's primary active underground gold mining operation, are correct.
The Sandur hill range in the Ballari-Vijayanagara region is an established mining center rich in hematite iron ore and manganese reserves. Furthermore, the Hutti Gold Mine located in Raichur district continues to operate as India's premier underground gold mining facility.

Step-by-Step Solution

1
Evaluate the mineral reserves of the Sandur schist belt in Karnataka.
The Sandur hill region in Ballari-Vijayanagara district is renowned for extensive deposits of high-grade hematite iron ore and associated manganese ore.
Geological survey records confirm the Sandur schist belt as a key mining hub in South India.
2
Analyze gold mining infrastructure in Karnataka.
Hutti Gold Mine in Raichur district remains active as India's main primary gold extraction site, unlike Kolar Gold Fields (KGF) which ceased operations in 2001.
HGML operates active underground extraction shafts at Hutti.
3
Verify soil mapping across Karnataka's agro-climatic zones.
Black soils (Regur) dominate the Northern Maidan/Dry Zone, while laterites predominate in coastal Karnataka and the Western Ghats.
Lateritization requires high temperature and heavy seasonal rainfall typical of coastal and highland zones, not the semi-arid northern plains.
4
Inspect petroleum resource distribution in India.
Karnataka has no crude oil reserves; petroleum production in India is concentrated in Assam, Gujarat, Rajasthan, and offshore basins.
The Precambrian igneous and metamorphic terrain of Malnad lacks sedimentary hydrocarbon-bearing formations.
