👉 Sulcus is a type of feature in mineralogy that is characterized by the presence of small, round or irregularly shaped spaces within a rock. These spaces are often filled with minerals and can have different sizes and shapes depending on their composition.
Sulcations occur in many rocks and can be found in various types of formations such as igneous, sedimentary, metamorphic, and plutonic. They are important because they provide information about the mineralogy and rock history of a particular location
