Question

Match the Precambrian lithounits in Group I with corresponding cratons in Group II. 

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

Hint:

Precambrian lithounits are grouped based on their geological history and association with specific cratons.

Answer 1

The Correct Option is C

Step 1: Understanding Precambrian Lithounits.
- The Kolhan Group is associated with the Singhbhum craton (P-3).
- The Debari Group is associated with the Dharwar craton (Q-4).
- The Babadham Group is associated with the Aravalli craton (R-1).
- The Sukma Group is associated with the Bastar craton (S-2).
Step 2: Analyzing the options.
(A) P-2, Q-3, R-4, S-1: Incorrect — The cratons are matched incorrectly.
(B) P-3, Q-4, R-1, S-2: Correct — This matches each lithounit with its correct craton.
(C) P-1, Q-2, R-4, S-3: Incorrect — The cratons are matched incorrectly.
(D) P-4, Q-3, R-1, S-2: Incorrect — The lithounits are mismatched with their cratons.
Step 3: Conclusion.
The correct answer is (B) P-3, Q-4, R-1, S-2, as it correctly matches the lithounits with their corresponding cratons.
