EspañolSTRIATION
(Redirected from Striations)
In bodybuilding, 'striations' are the tiny grooves of muscle across major muscle groups characteristic of a well-developed body. Chest striations are expected at low level competition, as they are indicative of muscularity and low body fat, whereas a Christmas tree in the lower back and striations in the glutes are expected at top level competition.
Standard bodybuilding textbooks recommend a number of techniques for developing striations, which include limiting calorific intake, spot-training, and training to failure on a wide variety of exercises for the relevant body part.
In geology, glacial striations are grooves or lines inscribed on the surface of a rock, produced by a geological process such as glacial flow. Other erosional processes can also create striations for example: mass movement, water torrents, and faulting. The striations usually occur in a group of roughly parallel lines.
In mineralogy striations are thin parallel lines (often microscopic) present in a mineral due to crystal twinning.
In fracture mechanics striations are thin parallel lines (microscopic) present in a material due to fatigue cracking. The thin parallel lines that can be seen macroscopically are called beachmarks.

Geologic uses
In geology, glacial striations are grooves or lines inscribed on the surface of a rock, produced by a geological process such as glacial flow. Other erosional processes can also create striations for example: mass movement, water torrents, and faulting. The striations usually occur in a group of roughly parallel lines.
In mineralogy striations are thin parallel lines (often microscopic) present in a mineral due to crystal twinning.
Fracture Mechanics
In fracture mechanics striations are thin parallel lines (microscopic) present in a material due to fatigue cracking. The thin parallel lines that can be seen macroscopically are called beachmarks.
