WebLecture notes are available as PDF files. You may need to install Acrobat Reader to obtain the PDF documents. WebApr 29, 2024 · INTRODUCTION: Fold is a wave like structure which is formed by bending or flexuring of any type of planes or layers in igneous, sedimentary and metamorphic rocks due to compressional force. Folds are best displayed by stratified formations. They may be inferred from various kinds of data.

Webfold, in geology, undulation or waves in the stratified rocks of Earth’s crust. Stratified rocks were originally formed from sediments that were deposited in flat horizontal sheets, but in a number of places the strata are no longer horizontal but have been warped. Sometimes the warping is so gentle that the inclination of the strata is barely perceptible, or the warping … WebIn structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation.
