Question:

Tillite with faceted boulders and green shale with dropstones characterize the lithology of:

Show Hint

Glacial deposits like tillites and dropstones are commonly associated with formations from regions affected by past ice sheets.

The Correct Option is C

Solution and Explanation

The Talchir Formation is characterized by tillite with faceted boulders and green shale with dropstones. These features are indicative of glacial deposits, where the dropstones are often associated with ice-rafted debris. The faceted boulders are formed by glacial abrasion. Therefore, the correct answer is (C): Talchir Formation.
- Lameta Formation (A) is known for its sedimentary deposits but does not feature the specific characteristics of glacial tillite.
- Bagra Formation (B) is not associated with glacial tillite, but rather with different sedimentary processes.
- Panchet Formation (D) also does not exhibit the glacial features found in the Talchir Formation.
Thus, the correct lithology is associated with the Talchir Formation.
