Question
Which one of the matches is correct for the stratigraphic unit and their ages?
Stratigraphic Unit Period A Dhosa Oolite E Palaeogene B Karai Shale F Cretaceous C Maleri Formation G Jurassic D Lakadong Limestone H Triassic
The correct answer is
A-G, B-F, C-H, D-E
Stratigraphic Units and Geological Ages Matching
The question requires matching specific stratigraphic units with their correct geological periods. Based on the correct pairing provided:
| Stratigraphic Unit | Geological Period |
|---|---|
| A. Adhosa Oolite | G. Jurassic |
| B. Karai Shale | F. Cretaceous |
| C. Maleri Formation | H. Triassic |
| D. Lakadong Limestone | E. Palaeogene |
Detailed Matching Explanation
Here's a breakdown of the correct matches:
- Adhosa Oolite (A) is correctly matched with the Jurassic period (G). This unit is known from the Kutch region of India and represents Jurassic marine deposits.
- Karai Shale (B) corresponds to the Cretaceous period (F). This formation, found in the Cauvery Basin, contains significant Cretaceous marine sequences.
- Maleri Formation (C) is accurately paired with the Triassic period (H). This formation in the Pranhita-Godavari Basin is famous for its Late Triassic vertebrate fossils.
- Lakadong Limestone (D) is correctly associated with the Palaeogene period (E). This limestone member is part of the Eocene succession in the Shillong Plateau.
Therefore, the correct sequence of matches is A-G, B-F, C-H, D-E.
