In structural geology we are most interested in fabrics that originate when rocks are deformed. Fabrics are common in folded rocks, and if fabrics develop at the same time as folding they often have a very specific relationship to folds. Fabrics may be planar or linear. Planar fabrics are also called foliations. meissner california

WebDefinition and Usage. A recumbent fold is one in which the axial plane is essentially horizontal, with the limit of variation of axial-planar dip, and the resulting limit of plunge, being 10° ( Turner and Weiss, 1963; Fleuty, 1964 ). It is a sideways-closing neutral structure that is neither a synformal nor an antiformal fold. WebOverturned folds These occur when both limbs dip in the same direction. This condition exists when the fold axis dips at an angle less than 45°. Plunging folds Both symmetrical and asymmetrical folds can plunge. The plunge is defined by fold axis that dips along the axial plane. This creates an effect of the fold “disappearing” and ...
