Question

Which of the following stratigraphic successions is/are arranged in CORRECT chronological order?

• A. Muth Quartzite - Syringothyris Limestone - Fenestella Shale - Panjal Volcanics
• B. Barakar Formation - Bijori Formation - Pachmarhi Formation - Bagra Formation
• C. Chiravati Group - Papaghni Group - Nallamalai Group - Kurnool Group
• D. Kaimur Group - Semri Group - Bhander Group - Rewa Group

Hint:

Stratigraphy questions are best solved by memorizing the correct chronological order of formations in Gondwana and Cuddapah basins. Remember: Barakar is Lower Gondwana, while Kurnool is the youngest in Cuddapah.

Answer 1

The Correct Option is B, C

Step 1: Recall the stratigraphy of Vindhyan and Gondwana sequences.
- Gondwana succession: Barakar → Bijori → Pachmarhi → Bagra (chronological order). Thus, option (B) is correct.
- Cuddapah Basin: Chiravati Group (oldest) → Papaghni → Nallamalai → Kurnool (youngest). Thus, option (C) is correct.

Step 2: Check other options.
- Option (A): Incorrect because Panjal Volcanics (Permian-Triassic) are older than Syringothyris Limestone and Fenestella Shale.
- Option (D): Incorrect order of Vindhyan succession. Correct order is: Semri (oldest) → Kaimur → Rewa → Bhander (youngest).

Final Answer: \[ \boxed{\text{(B) and (C)}} \]
