The term 'Fine Grooves' is often used to refer to the striae, or grooves, that are found on the surface of rocks and other geological formations. These striae are created by the movement of glaciers, wind, and water erosion, and can be seen in many places around the world. They are usually very thin and can be difficult to see without magnification. Fine Grooves are an important part of geology and can provide valuable information about the history of a particular area.
