Question

Which one of the following lithostratigraphic units is of Phanerozoic Eon?

• A. Sargur Group
• B. Semri Group
• C. Uttatur Group
• D. Papaghni Group

Hint:

When identifying Phanerozoic units, it is important to note that these units are associated with significant fossil records and are often part of sedimentary rock formations from the Mesozoic and Cenozoic eras.

Answer 1

The Correct Option is C

Step 1: Understanding the question.
The question asks about lithostratigraphic units from the Phanerozoic Eon. The Phanerozoic Eon is known for the development of abundant life and the deposition of many sedimentary units.
Step 2: Analyzing the options.
(A) Sargur Group: The Sargur Group is from the Archaean Eon, not the Phanerozoic Eon.
(B) Semri Group: The Semri Group belongs to the Lower Gondwana sequence, which is a Phanerozoic unit. However, it does not correctly answer the question, as the Uttatur Group is the correct choice.
(C) Uttatur Group: Correct — The Uttatur Group is a Phanerozoic unit and is a part of the Deccan Traps sequence, making it the correct answer.
(D) Papaghni Group: This is from the Proterozoic Eon, not from the Phanerozoic.
Step 3: Conclusion.
The correct answer is (C) Uttatur Group, as it is a Phanerozoic unit.
