Folding in geology definition
WebIn structural geology, a syncline is a fold with younger layers closer to the center of the structure. A synclinorium (plural synclinoriums or synclinoria) is a large syncline with superimposed smaller folds. Synclines are typically a downward fold, termed a synformal syncline (i.e. a trough); but synclines that point upwards, or perched, can be found when … WebGeologic folds are layers of rock that are curved or bent by ductile deformation. Folds are most commonly formed by compressional forces …

WebFolds are classified into two main types namely anticlines or up-folds and synclines or down-folds. 1. Anticline Folds: An anticline consists of beds bent upwards with limbs dipping away from each other. 2. Syncline Folds: A syncline consists of beds bent downwards with limbs dipping towards each other. 3.

Webuplift, in geology, vertical elevation of the Earth’s surface in response to natural causes. Broad, relatively slow and gentle uplift is termed warping, or epeirogeny, in contrast to the more concentrated and severe orogeny, the uplift associated with earthquakes and mountain building.
WebIn a geological context, crenulation or crenulation cleavage is a fabric formed in metamorphic rocks such as phyllite, schist and some gneiss by two or more stress directions causing the formation of the superimposed foliations . Formation [ edit] Crenulations form when an early planar fabric is overprinted by a later planar fabric.
