Question

Which one of the following is the oldest stratigraphically?

• A. Bababudan Group
• B. Sargur Group
• C. Chitradurga Group
• D. Ranibennur Group

Hint:

In Indian Precambrian stratigraphy, the Sargur Group is considered older than the Dharwar Supergroup units.

Answer 1

The Correct Option is B

Concept:
In stratigraphy, older rock groups occur lower in the geological time sequence, while younger groups are deposited later.

Step 1: Identify the groups.
The given groups belong to Precambrian stratigraphy of the Indian shield region.

Step 2: Compare relative ages.
Sargur Group is among the oldest supracrustal rock sequences. \[ \text{Sargur Group} \Rightarrow \text{older than Bababudan and Chitradurga groups} \]

Step 3: Final answer.
Thus, the oldest stratigraphically among the given options is Sargur Group. \[ \therefore \text{Correct Answer is (B)} \]
