2. Fold (geology) - Wikipedia

   en.wikipedia.org/wiki/Fold_(geology)

   A fold axis "is the closest approximation to a straight line that when moved parallel to itself, generates the form of the fold". [2] (Ramsay 1967). A fold that can be generated by a fold axis is called a cylindrical fold. This term has been broadened to include near-cylindrical folds. Often, the fold axis is the same as the hinge line. [3] [4]

3. 3D fold evolution - Wikipedia

   en.wikipedia.org/wiki/3D_Fold_Evolution

   In geology, 3D fold evolution is the study of the full three dimensional structure of a fold as it changes in time. A fold is a common three-dimensional geological structure that is associated with strain deformation under stress .

4. Anticline - Wikipedia

   en.wikipedia.org/wiki/Anticline

   If the angle between the limbs is large (70–120 degrees), then the fold is an "open" fold, but if the angle between the limbs is small (30 degrees or less), then the fold is a "tight" fold. [4] If an anticline plunges (i.e., the anticline crest is inclined to the Earth's surface), it will form V s on a geologic map view that point in the ...

5. Structural geology - Wikipedia

   en.wikipedia.org/wiki/Structural_geology

   For economic geology such as petroleum and mineral development, as well as research, modeling of structural geology is becoming increasingly important. 2D and 3D models of structural systems such as anticlines, synclines, fold and thrust belts, and other features can help better understand the evolution of a structure through time.

6. Chevron (geology) - Wikipedia

   en.wikipedia.org/wiki/Chevron_(geology)

   Chevron folding preferentially occurs when the bedding regularly alternates between contrasting competences. [1] Turbidites, characterized by alternating high-competence sandstones and low-competence shales, provide the typical geological setting for chevron folds to occur. Perpetuation of the fold structure is not geometrically limited.

7. Lineation (geology) - Wikipedia

   en.wikipedia.org/wiki/Lineation_(geology)

   Rods form a conspicuous coarse lineation, frequently highly contrasting with the surrounding rock in regions that was under high strain. The term rod or rodding, in geology, broadly refers to a mass of rock, which has assumed a cylindrical shape while accommodating strain; however, different definitions are found in the literature.
