Which of the following stratigraphic successions is/are arranged in CORRECT chronological order?
Show Hint
- Muth Quartzite - Syringothyris Limestone - Fenestella Shale - Panjal Volcanics
- Barakar Formation - Bijori Formation - Pachmarhi Formation - Bagra Formation
- Chiravati Group - Papaghni Group - Nallamalai Group - Kurnool Group
- Kaimur Group - Semri Group - Bhander Group - Rewa Group
The Correct Option is B, C
Solution and Explanation
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: \[ \boxed{\text{(B) and (C)}} \]
