With reference to the mineral resources and industrial economy of Andhra Pradesh, the Mangampet mining complex, which contains the single largest deposit of bedded barytes (barite) in India, is situated in which of the following districts?

  1. A
    Nellore district
  2. B
    Kurnool district
  3. YSR Kadapa districtAnswer
  4. D
    Ananthapuramu district

Answer

YSR Kadapa district
The Mangampet barytes deposit is located in the Obulavaripalli Mandal of YSR Kadapa district in Andhra Pradesh. Discovered in the volcano-sedimentary sequence of the Cuddapah Supergroup, this deposit represents one of the largest single bedded deposits of grey and bedded barytes in the world. It accounts for the overwhelming majority of India's production and export of drilling-grade barytes, contributing substantially to the state's non-fuel mineral revenues.

Step-by-Step Solution

1
Identify the target mineral and geographic location mentioned in the stem
The target mineral is bedded barytes (used extensively as a weighting agent in oil and gas well drilling mud) located in the Mangampet deposit of Andhra Pradesh.
Establishing the specific mineral and state helps narrow down the regional geological belts.
2
Map the Mangampet mining area to its administrative district within Andhra Pradesh
Mangampet is situated in Obulavaripalli Mandal within YSR Kadapa (formerly Cuddapah) district in the Cuddapah Basin.
The Mangampet deposit constitutes over 90% of India's total extractable barytes reserves and is a cornerstone of the district's mining economy.
3
Differentiate from other major mining districts in the state
Nellore is associated with mica, Kurnool with cement-grade limestone, and Ananthapuramu with gold and iron ore.
Prevents confusing adjacent Rayalaseema and Coastal Andhra mineral zones.
