Question

Select the correct statement(s).

• A. Laccoliths are convex upward whereas lopoliths are convex downward bodies
• B. Laccoliths can form from any type of magma whereas lopoliths form only from basaltic magma
• C. Laccoliths show layered structures whereas lopoliths lack any layering
• D. Laccoliths are smaller in dimensions than lopoliths

Hint:

Laccoliths and lopoliths are both types of igneous intrusions, but they differ in size, shape, and the type of magma that forms them.

Answer 1

The Correct Option is A, B, D

Step 1: Understanding Laccoliths and Lopoliths.
- Laccoliths are small, dome-shaped intrusions with an upward convex shape, while lopoliths are larger and have a downward convex shape (A).
- Laccoliths can be formed from various types of magma, while lopoliths are more commonly associated with basaltic magma (B).
- Laccoliths often show layering, while lopoliths may lack any noticeable layering (C).
- Laccoliths are smaller than lopoliths (D).
Step 2: Conclusion.
The correct answer is (A) and (B).
