Quartz is a mineral that commonly exhibits striations on its surface. These are often caused by growth patterns during its formation, giving it a lined or grooved appearance.
striations
Minerals that exhibit striations include feldspar, particularly plagioclase, and quartz. Striations are fine, parallel lines or grooves found on the crystal surfaces of these minerals, often resulting from their crystallization processes. Other minerals, such as calcite and some varieties of pyroxene, can also show striations, which can be important for identification in mineralogy.
Striations in the human body are primarily seen in skeletal muscle tissue and cardiac muscle tissue. In skeletal muscles, these striations appear as alternating light and dark bands due to the arrangement of actin and myosin filaments, which facilitate voluntary movement. In cardiac muscle, striations are also present, but the muscle fibers are interconnected, allowing for coordinated contractions of the heart. Smooth muscle, in contrast, does not exhibit striations.
Minerals that commonly exhibit striations include plagioclase feldspar and quartz. Striations are often seen as fine, parallel lines on the crystal surfaces, particularly in plagioclase due to its twinning. Other minerals, such as calcite and some varieties of mica, may also display striations, although they are less common. These features can help in the identification of minerals under a microscope or in hand samples.
Vertical grooves are called "striations."
Kyanite is a silicate mineral that is characterized by its striations on the crystal faces. These striations are fine grooves or ridges that run parallel to the crystal's length and help differentiate kyanite from other minerals.

Yes they have Cross Striations
Striations are light and dark bands on skeletal and caridac muscle fibers. Smooth muscle lacks striations
When a Glacier moves over an area of soft or hard rock it may have smaller stones underneath it, these small stones scratch into the larger rock making the Striations. They show which direction the Glacier travelled in.
The marble was smokey grey with black and white striations.
A sodium feldspar with twinning striations is called albite, while a calcium feldspar with twinning striations is called anorthite.
They are called striations.
Cross-striations form cardiac muscle. The crossed formation makes the tissue and muscle stronger.
