Charoite is named after the nearby Charo River.
Charoite is an unsual mineral and of rare occurence. It formed from alteration of limestones by the close presences of an alkali-rich nephline syenite intrusion. The heat, pressure and more importantly, the infusion of unique chemicals into the rock is responsible for the transformations into new minerals such as charoite. Charoite is found in only one location - along the Chary River at Aldan in Russia. This part of Russia is known for its forbidding climate and terrain and as a traditional place of exile for political prisoners. Why charoite has not been found in other locations is not fully understood. But it is probably due to a combination of a chemically unique limestone reacting with a chemically unique intrusion and subjected to unique physical conditions. |
