Question:
Which one of the following sedimentary structures is formed by rapid release of water?
Which one of the following sedimentary structures is formed by rapid release of water?
Show Hint
Convolute lamination forms due to rapid water movement or deformation, often under high energy conditions, which can create intricate folds in sediment layers.
Updated On: Sep 6, 2025
- Ripple lamination
- Gutter cast
- Convolute lamination
- Prod mark
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand Sedimentary Structures.
- Ripple lamination is formed by oscillatory water movements, typically in shallow water environments, but not necessarily due to rapid water release.
- Gutter cast is a sedimentary structure formed by rapid water release, especially during high-energy events like floods.
- Convolute lamination results from deformation under high pressure or rapid water movement, which can cause folding and complex structures in the sediment layers.
- Prod mark is an imprint from an organism and unrelated to water release.
Thus, the correct answer is (C) Convolute lamination.
Final Answer: \[ \boxed{\text{Convolute lamination}} \]
