Háfita

Háfita is a mineral that belongs to the zeolite group. It is a tectosilicate, meaning it is composed of silica tetrahedra linked together in a three-dimensional framework. Háfita is typically colorless or white, but it can also appear in shades of yellow, brown, or gray due to impurities. It is named after its type locality, the Háfur mountain in Iceland.

Háfita is known for its unique crystal structure, which is characterized by its large, open channels. These channels can accommodate various cations, such as sodium, potassium, and calcium, as well as water molecules. This property makes háfita a useful material in ion exchange processes and as a catalyst in various chemical reactions.

Háfita is relatively rare and is typically found in volcanic rocks, particularly in areas with significant geothermal activity. It has been reported from several locations around the world, including Iceland, the United States, and Japan. Despite its rarity, háfita has garnered interest from mineral collectors and researchers due to its interesting crystal structure and potential applications in various fields.
