Maksiimin
Maksiimin is a rare and unique mineral discovered in the late 20th century. It was first identified in the Maksiimka River in the Kola Peninsula of Russia. The mineral is named after the river, which in turn is named after the Russian word for "great," reflecting the significance of its discovery. Maksiimin is characterized by its distinctive crystal structure and vibrant blue color, which is a result of the presence of copper and sulfur in its composition. The mineral is typically found in association with other copper-bearing minerals, such as chalcopyrite and bornite. Maksiimin has a hardness of 3.5 on the Mohs scale and a specific gravity of approximately 4.2. It is often used in the study of mineralogy and geology due to its rarity and unique properties. Despite its scientific interest, maksiimin has no known commercial applications.
