Haardus

Haardus is a term used in the field of geology to describe a type of rock that is formed through the process of metamorphism. Metamorphism occurs when existing rock is subjected to high temperatures and pressures, causing physical and/or chemical changes to the original rock. Haardus is specifically a type of metamorphic rock that is characterized by its fine-grained texture and the presence of minerals such as garnet, staurolite, and kyanite. These minerals are indicative of the high-pressure conditions that the rock has experienced during its metamorphic history. Haardus is often found in regions where there has been significant tectonic activity, such as mountain ranges or areas of crustal thickening. It is an important rock type in the study of geological processes and the history of the Earth's crust.
