striations
Lines etched lengthwise
Striations are parallel lines, grooves, or ridges on a surface.
The term appears in geology for marks left by glaciers on rock, in biology for the banded appearance of muscle tissue, and in forensics for the unique grooves a gun barrel leaves on a bullet.
Any surface showing fine parallel markings has striations: The striations in the marble caught the light.
