Canasite is a mineral whose name is derived from its chemical composition of calcium (Ca), sodium (Na), and silicon (Si). It also contains fluorine, hydrogen, oxygen, and potassium. It was approved in 1959 by IMA. It occurs in Russia mostly.  Purple canasite may be confused with stichtite, but recent research has found that the mineral advertized as canasite is a new specimen.  There are two varieties of canasite: fluorcanasite and frankamenite. References External links URL URL URL
Canasite is a mineral whose name is derived from its chemical composition of calcium (Ca), sodium (Na), and silicon (Si). It also contains fluorine, hydrogen, oxygen, and potassium. It was approved in 1959 by IMA. It occurs in Russia mostly. Twinning usually occurs. Purple canasite may be confused with stichtite, but recent research has found that the mineral advertized as canasite is a new specimen. It has a barely detectable, 1.12\% potassium radioactivity based on the GRapi unit (Gamma Ray American Petroleum Institute Units). It consists of mostly oxygen (41.98\%), silicon (26.8\%) and calcium (15.93\%), but otherwise contains sodium (7.31\%), potassium (6.22\%), which gives its' irradiation, fluorine (1.51\%) and hydrogen (0.24\%).
