Felsik

Felsik is a term that can refer to several things, most commonly a type of rock or a geological formation. In some contexts, it is used as a colloquial or regional term for felsic igneous rocks. Felsic rocks are characterized by their high content of silica and alkali feldspars, and often include quartz, muscovite, and biotite. They are typically light in color. Examples include granite and rhyolite.

The term "felsik" can also appear in less common or specialized contexts. For instance, in some discussions related to mineralogy or petrology, variations on this spelling might be encountered, though "felsic" is the standard scientific term. It is important to consider the specific context in which "felsik" is used to determine its precise meaning. Without further context, it is most likely referring to the geological classification of rocks. This classification system helps geologists understand the origin and composition of rocks found on Earth and other celestial bodies. The properties of felsic rocks, such as their hardness and resistance to weathering, influence the landscapes they form.
