Cótonsisaheet

Cótonsisaheet is a rare and unique mineral discovered in the late 20th century. It is primarily found in the volcanic regions of Iceland and the Philippines. The mineral is characterized by its distinctive, cotton-like texture, which gives it its name. This texture is a result of the mineral's unique crystal structure, which is composed of long, fibrous crystals that resemble cotton fibers.

Cótonsisaheet is a silicate mineral, belonging to the amphibole group. It is typically found in association with other amphibole minerals such as tremolite and actinolite. The mineral is often found in metamorphic rocks, particularly those that have undergone contact metamorphism. It is also found in some igneous rocks, particularly those that are rich in silica.

The mineral has a hardness of 5-6 on the Mohs scale and a specific gravity of approximately 3.2. It is typically found in shades of green, brown, and black, although it can also be found in shades of white and yellow. The mineral is not known to have any significant economic value, but it is of interest to mineral collectors and geologists due to its unique appearance and rarity.
