Toksiliite
Toksiliite is a rare mineral discovered in 2008, found in the Toksili mine in the Toksili district of the Osh Region in Kyrgyzstan. It is named after the mine where it was first discovered. Toksiliite is a member of the zeolite group, which are a group of minerals with a similar structure and composition. It is typically colorless or white, but can also be found in shades of yellow, green, or brown due to impurities. The mineral has a hardness of 4 on the Mohs scale and a specific gravity of approximately 2.2. It is often found in association with other zeolites such as chabazite and analcime. Toksiliite is not currently known to have any significant industrial or commercial uses, but it is of interest to mineralogists due to its rarity and unique properties. Its chemical formula is (Na,K,Ca)2(Al,Si)4O10·2H2O, indicating that it contains sodium, potassium, calcium, aluminum, silicon, oxygen, and water. The mineral's crystal system is monoclinic, and it typically forms prismatic crystals. Despite its rarity, toksiliite remains an important subject of study in the field of mineralogy.
