Question

Match the stratigraphic units in Group-I with the sedimentary basins in Group-II.

	Group-I		Group-II
P	Ramgundam	1	Chhattisgarh
Q	Raipur Formation	2	Kaladgi
R	Bagalkot Group	3	Marwar
S	Sonia Sandstone	4	Godavari

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

Hint:

In Indian stratigraphy, always remember key basin–formation pairs: Godavari–Ramgundam, Chhattisgarh–Raipur, Kaladgi–Bagalkot, and Marwar–Sonia Sandstone. This helps in quick elimination during matching questions.

Answer 1

The Correct Option is B

Step 1: Recall associations of stratigraphic units with basins. - Ramgundam Sandstone is found in the Godavari basin.
- Raipur Formation belongs to the Chhattisgarh basin.
- Bagalkot Group is associated with the Kaladgi basin.
- Sonia Sandstone is characteristic of the Marwar basin.
Step 2: Match accordingly. \[ P \rightarrow 4,\quad Q \rightarrow 1,\quad R \rightarrow 2,\quad S \rightarrow 3 \] Step 3: Verify with given options. This corresponds to option (B). \[ \boxed{(B)\; P-4,\; Q-1,\; R-2,\; S-3} \]
