Fold - Spatial object type

Definition: One or more systematically curved layers, surfaces, or lines in a rock body.

Description: A fold denotes a structure formed by the deformation of a Geologic Structure to form a structure that may be described by the translation of an abstract line (the fold axis) parallel to itself along some curvilinear path (the fold profile). Folds have a hinge zone (zone of maximum curvature along the surface) and limbs (parts of the deformed surface not in the hinge zone).

Subtype of: Geologic Structure


Attributes

Definition: The type of the fold.

Description: Folds are typed according to the concave/convex geometry of the fold relative to the earth surface, and the relationship to younging direction in folded strata if known.EXAMPLE: antiform, synform, anticline, syncline, etc.
