Webof this lecture (and all of the Chapter 6 exercises) will be restricted to anticlines and synclines. Once you understand the basic difference between anticlines and synclines, the rest of fold morphology is fairly consistent. Folds can be symmetrical or asymmetrical. The former is when the fold limbs have an equal, but opposite angle of dip. WebAn anticline fold is convex up: the layered strata dip away from the center of the fold (if you drew a line across it, the anticline would resemble a capital letter “A”). A syncline is a concave upward fold in which the layered strata dip towards the center of the fold (it resembles a “U”). Folds have three main parts: a fold axis (also ... how fast ram for gaming
