Question

The famous "Gondwana Supergroup" in India is primarily known for its deposits of?

• A. Petroleum
• B. Coal
• C. Limestone
• D. Iron ore

Hint:

Gondwana in India = \textbf{Coal reserves}. Think: Ancient forests $\rightarrow$ Burial $\rightarrow$ Coal formation.

Answer 1

The Correct Option is B

Concept: The Gondwana Supergroup refers to a sequence of sedimentary rocks in India formed during the late Paleozoic to early Mesozoic eras. These rocks were deposited in continental environments such as river basins and swamps. These formations are especially significant because they contain rich deposits of coal, which formed from the accumulation and compression of plant material in ancient swampy environments. Step 1:Understand the origin of Gondwana deposits.
The Gondwana sediments were laid down in basins under conditions favorable for lush vegetation, which later transformed into coal.
Step 2:Identify the major resource associated with these rocks.
India's major coal fields (e.g., Damodar Valley, Son Valley) are associated with Gondwana formations.
Step 3:Eliminate incorrect options.

• Petroleum is generally associated with marine sedimentary basins.
• Limestone forms in marine environments.
• Iron ore is typically linked with older Precambrian formations.

Step 4:Conclude the answer.
Thus, the Gondwana Supergroup is primarily known for coal deposits.
