Bodybuilding

---

In bodybuilding, striations are the tiny grooves of muscle across major muscle groups characteristic of a well-developed body. Chest striations are expected at top level competition, as they are indicative of muscularity and low body fat.

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.

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.
