| 10 Amazing Geological Folds You Should See |
Folds are some of the most common geological phenomena you see in the world – a geological fold occurs when planar (usually sedimentary) layers are curved and/or bent, permanently deformed due to outside pressure. Folds’ sizes can vary from microscopic to mountain sized.

Chevron folds are a structural feature characterized by repeated well behaved folded beds with straight limbs and sharp hinges. Well developed, these folds develop repeated set of v-shaped beds. They develop in response to regional or local compressive stress. Inter-limb angles are generally 60 degrees or less.

The Richat Structure in the Sahara Desert of Mauritania. Long considered to be an impact structure, it is now believed by most to be a structural dome. The Richat Structure is a deeply eroded, slightly elliptical dome with a diameter of 40 km. The sedimentary rock exposed in this dome ranges in age from Late Proterozoic within the center of the dome to Ordovician sandstone around its edges
