WebIn structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation.Folds in rocks vary in size from microscopic crinkles to … WebThe joints accommodate the larger compression stress (larger red arrows) by allowing the rock to stretch in the up-down direction (along the green arrows). Figure 13.22 Joints developing to accommodate the larger horizontal component of compression (large red arrows). Source: Steven Earle CC BY 4.0 view source Faulting Anticlines (upfolds) and synclines (downfolds) are very common geologic structures that form in pairs in response to compression. Anticlines and synclines will share a limb of the fold.
