Show answer & explanation
Correct answer: D
Concept — Mineral occurrence is controlled by geology rather than by administrative boundaries: a mineral is associated with characteristic rock settings and with a few well-known producing belts, even though most minerals occur in more than one of them. Mica is won from the pegmatite veins of the Chotanagpur plateau; limestone and dolomite come from carbonate sequences — the Vindhyan and Aravalli basins of Rajasthan and the magnesian carbonate tracts of the peninsular shield; gypsum comes from evaporite beds of arid basins and of a few Outer Himalayan valleys. So the method for any mineral-and-place matching item is: first identify the state and geological setting of each listed area, then pair it with the mineral whose known belt that area falls in.
Applying the method to the four areas
Mineral | Area | State | Setting that fixes the pair |
|---|---|---|---|
Mica | Dhengura | Jharkhand | A locality just south of Hazaribagh, inside the Koderma–Gaya–Hazaribagh pegmatite belt, which yields about half of India’s mica and the world’s finest ruby mica. |
Limestone | Tonk | Rajasthan | Vindhyan limestone of eastern Rajasthan; Tonk stands with Kota, Nagaur, Ajmer and Sawai Madhopur among the state’s limestone-producing districts. |
Dolomite | Salem | Tamil Nadu | The Chalk Hills magnesian-carbonate tract, where dolomite is worked alongside magnesite and crystalline limestone. |
Gypsum | Kangra | Himachal Pradesh | Evaporite gypsum reported from the Kangra–Chu valley of the Outer Himalaya. |
Reading the four pairs off in the order A, B, C, D therefore gives the code 3 1 4 2.
Cross-check — test the rival codes against the same settings and each one breaks on at least two pairs:
The code 1 2 3 4 would put dolomite at Dhengura and gypsum at Salem. Hazaribagh is mica country — Jharkhand’s dolomite lies in Singhbhum and Palamu — and Tamil Nadu’s gypsum is listed for Coimbatore, Tiruppur, Ramanathapuram and Perambalur, while Salem yields magnesite, dolomite and crystalline limestone.
The code 4 2 3 1 would put mica at Salem and gypsum at Tonk. Salem’s hills are a carbonate–magnesite tract rather than a pegmatite one, and Rajasthan’s gypsum is the Bikaner–Nagaur–Jaisalmer–Barmer evaporite belt, not Tonk.
The code 2 3 1 4 would put mica at Kangra and dolomite at Tonk, but Rajasthan’s dolomite districts are Ajmer, Alwar, Bhilwara, Jaipur and Jaisalmer, and the rocks worked in Kangra are limestone and slate.
Hence the correct code is 3 1 4 2 — mica with Dhengura, limestone with Tonk, dolomite with Salem and gypsum with Kangra.
