Question

Match the geological processes (Group I) with their examples in Indian stratigraphy (Group II). 
Group I                                                               Group II 
P. Permo-Carboniferous glaciation                    1. Ariyalur Group 
Q. Cretaceous marine transgression                  2. Siwalik Group 
R. Neogene fluvial sedimentation                      3. Talchir Formation 
S. Cretaceous inter-trappean sedimentation     4. Lameta Formation 
 

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

Hint:

Geological processes like glaciation, marine transgression, and fluvial sedimentation play key roles in shaping the sedimentary records of regions like the Siwalik and Talchir formations.

Answer 1

The Correct Option is A

Step 1: Understanding the question.
The question asks to match geological processes with their corresponding examples in Indian stratigraphy. Each process is related to a specific sedimentary deposit.
Step 2: Analyzing the options.
(A) P-3 Q-4 R-1 S-2: Correct — Permo-Carboniferous glaciation is represented by the Talchir Formation, Cretaceous marine transgression is seen in the Lameta Formation, Neogene fluvial sedimentation corresponds to the Ariyalur Group, and Cretaceous inter-trappean sedimentation is found in the Siwalik Group.
(B) P-2 Q-3 R-4 S-1: This combination is incorrect, as it mismatches the processes and formations.
(C) P-3 Q-2 R-1 S-4: This combination is incorrect, as it mismatches the processes and formations.
(D) P-4 Q-1 R-2 S-3: This combination is incorrect based on geological history and locations.
Step 3: Conclusion.
The correct answer is (A) P-3 Q-4 R-1 S-2, as it correctly matches the geological processes with the corresponding formations in Indian stratigraphy.
