Tinaksite (chemical formula ) is a mineral found in northern Russia. Tinaksite can be grayish-white, yellowish, orange, or brown, and it is often found in

charoite Charoite is a rare silicate mineral, first described in 1978. It was believed to be named after the Chara River, but due to the river being 70 km away from its discovery place, now it is believed to be named after the Russian word ''chary'', ...

. Its name is derived from its composition: titanium (Ti), sodium (Na) potassium (K) and silicon (Si). The International Mineralogical Association first recognized tinaksite as a mineral in 1965.
