Question

Match the following copper deposits in Group-I with their host rocks in Group-II.

	Group-I		Group-II
P	Khetri	1	Chlorite-biotite schist and soda-granite
Q	Mosabani	2	Garnetiferous chlorite schist
R	Malanjkhand	3	Metachert
S	Kalyadi	4	Tonalite-granodiorite-granite

• A. P-2, Q-3, R-4, S-1
• B. P-4, Q-1, R-2, S-3
• C. P-2, Q-1, R-4, S-3
• D. P-3, Q-4, R-1, S-2

Hint:

- Khetri → Garnetiferous chlorite schist.
- Mosabani → Chlorite–biotite schist and soda–granite.
- Malanjkhand → Tonalite–granodiorite–granite.
- Kalyadi → Metachert.

Answer 1

The Correct Option is C

Step 1: Khetri copper belt.
Khetri (Rajasthan) copper deposits are hosted in garnetiferous chlorite schists.
Thus, \( P \rightarrow 2 \).
Step 2: Mosabani copper deposits.
The Mosabani copper mines (Singhbhum shear zone, Jharkhand) occur in chlorite–biotite schist and soda–granite.
Thus, \( Q \rightarrow 1 \).
Step 3: Malanjkhand copper deposit.
Malanjkhand (Madhya Pradesh) is India’s largest open-pit copper mine, hosted in
tonalite–granodiorite–granite intrusive complex.
Thus, \( R \rightarrow 4 \).
Step 4: Kalyadi copper deposit.
Kalyadi (Karnataka) copper deposits are associated with metacherts.
Thus, \( S \rightarrow 3 \).
Step 5: Final matching.
\[ P \rightarrow 2, \quad Q \rightarrow 1, \quad R \rightarrow 4, \quad S \rightarrow 3 \] \[ \boxed{\text{Correct option is (C)}} \]
