Q: What are the characteristics of chevron folds?
A: Chevron folds are regular folded beds with straight limbs and sharp hinges. Well developed, these folds produce a set of v-shaped beds.
Q: How do chevron folds develop?
A: Chevron folds develop in response to compressive stress.
Q: What is the angle of chevron folds?
A: The angles of the folds are generally 60 degrees or less.
Q: What type of bedding helps with chevron folding?
A: Bedding that alternates between beds of different make-up helps with chevron folding.
Q: What is the typical geological setting for chevron folds to occur?
A: Turbidites, with alternating sandstones and shales, are the typical geological setting for chevron folds to occur.
Q: Can chevrons form in land deposits?
A: Yes, chevrons can form in land deposits, especially where there are sand dunes.
