Primary and Tectonic Folds in the Context of Exploration and Mining

Folds are the most familiar, and commonly the most spectacular, manifestation of bulk heterogeneous deformation in rocks. They occur at all scales from the microscopic to the scale of the whole lithosphere. Folds form under a range of conditions in igneous, sedimentary and metamorphic rocks.



A necessity for identification of folds is the presence of some planar layering that can define the
