Which among the following is correctly matched? (A) Mando-ki-pal – Feldspar (B) Talwara – Lead and Zinc (C) Kherwara – Asbestos (D) Rishabhdev – Mica

Correct — option (4), C.

Option (4) points to statement C, Kherwara – Asbestos. Checked one by one, only that pair matches the sources.

(C) Kherwara – Asbestos: the Udaipur District Gazetteer, with data to 1972-73, says the district's asbestos deposits are found near Nathdwara, Molaka, Gudha, Rikhabdeo, Kunthal and Kherwara, most of them of the amphibole type.

(A) Mando-ki-pal – Feldspar: Rajasthan's Department of Mines and Geology (DMG) names Mando ki pal, in Dungarpur district, among the important deposits of fluorite.

(B) Talwara – Lead and Zinc: the Banswara District Gazetteer (1974) names Talwara among Banswara's manganese localities, and DMG's list of lead-zinc-silver deposits does not include it.

(D) Rishabhdev – Mica: the Udaipur Gazetteer ties Rikhabdeo (Rishabhdev) to asbestos, soapstone and serpentine carving. The Indian Bureau of Mines' 2018 Rajasthan review places mica in Ajmer and Bhilwara districts.

Only C holds, so the answer is option (4), C.

Why the others are wrong

• (1)
  B — Option (1) points to B, Talwara – Lead and Zinc. The Banswara District Gazetteer lists Talwara among the district's manganese localities, and places Banswara's small lead-ore occurrences at Wardiya and Peepal Khoont, not Talwara.

  DMG's important lead-zinc-silver deposits are at Zawar (Udaipur), Rajpura-Dariba-Bethumi and Sindesar Kalan-Khurd (Rajsamand), Rampura-Agucha and Pur-Banera (Bhilwara), Dehri (Sirohi) and Kayar-Ghugra and Sawar (Ajmer).

• (2)
  D — Option (2) points to D, Rishabhdev – Mica. The Udaipur District Gazetteer lists Rikhabdeo among asbestos deposits, including a small quantity of chrysotile, and among soapstone occurrences; its stone carvers work serpentine.

  The Indian Bureau of Mines' 2018 Rajasthan review names mica in Ajmer and Bhilwara districts. Neither source ties Rishabhdev to mica.

• (3)
  A — Option (3) points to A, Mando-ki-pal – Feldspar. DMG lists Mando ki pal and Kahila, in Dungarpur district, as important fluorite deposits, with proved resources and CaF2 content.

  Feldspar is a different mineral; DMG's feldspar entry names districts such as Ajmer, Bhilwara, Rajsamand and Pali. Mando-ki-pal belongs with fluorite.

Asbestos is a fibrous mineral that occurs in two main types, chrysotile (serpentine asbestos) and amphibole asbestos. The Udaipur District Gazetteer found both types in the district, most of it amphibole, with a small quantity of chrysotile near Rikhabdeo.

The Indian Bureau of Mines' Indian Minerals Yearbook 2018 lists asbestos (amphibole) in Ajmer, Bhilwara, Dungarpur, Pali, Rajsamand and Udaipur districts of Rajasthan.

Fluorite is calcium fluoride, CaF2. DMG gives its important Rajasthan deposits as Mando ki pal and Kahila in Dungarpur, with a smaller resource at Karaka in Jalore.

Key facts

• Udaipur District Gazetteer (data to 1972-73): asbestos deposits lie near Nathdwara, Molaka, Gudha, Rikhabdeo, Kunthal and Kherwara, mostly of the amphibole type.
• Udaipur District Gazetteer: a small quantity of chrysotile asbestos is found near Rikhabdeo, whose stone carvers make toys and images of serpentine.
• Rajasthan DMG: Mando ki pal and Kahila in Dungarpur district are important fluorite deposits.
• Banswara District Gazetteer (1974): Talwara is among the district's manganese localities, with Khunta Kalan, Itala, Tambosara and Sagwan.
• IBM, Indian Minerals Yearbook 2018 (Rajasthan): asbestos (amphibole) in Ajmer, Bhilwara, Dungarpur, Pali, Rajsamand and Udaipur; mica in Ajmer and Bhilwara.

Common traps

• Mixing option numbers with statement letters. Option (1) prints B, option (2) D, option (3) A and option (4) C, so the letter printed in an option has to be traced back to its statement.
• Placing Talwara with lead and zinc. The Banswara Gazetteer names it among manganese localities; DMG's lead-zinc deposits are at places such as Zawar and Rampura-Agucha.
• Mixing up two Kherwaras. The Udaipur Gazetteer's Kherwara has asbestos; the Banswara Gazetteer names another Kherwara, in Banswara, for iron and for beryl with mica.

• practice — not a real PYQ

  Mando ki Pal in Dungarpur district of Rajasthan is an important deposit of –

  • (a)Feldspar
  • (b)Fluorite
  • (c)Manganese
  • (d)Asbestos
  Answer(2) — DMG lists Mando ki pal among Rajasthan's important fluorite deposits. Option (1), feldspar, is listed for districts such as Ajmer and Bhilwara; option (3), manganese, for Banswara localities such as Talwara; option (4), asbestos, for Udaipur localities such as Kherwara.
• practice — not a real PYQ

  Which of the following localities of Rajasthan is associated with manganese?

  • (a)Zawar
  • (b)Talwara
  • (c)Kherwara
  • (d)Rampura-Agucha
  Answer(2) — The Banswara District Gazetteer names Talwara among its manganese localities. Option (1), Zawar, and option (4), Rampura-Agucha, are lead-zinc-silver deposits on DMG's list; option (3), Kherwara, is an asbestos locality in the Udaipur Gazetteer.
