Johachidolite

Johachidolite

Named for the type locality in the Johachide sidtrict in the Kankyo Hodu Prefecture of North Korea. Johachidoite is a rare mineral that can be found only at its type locality and is also attributed to the Mogok region of Myanmar. Jodachidolite occurs at its type locality in a nepheline dike that cuts limestone. It has a blue fluorescence under short-wave ultraviolet light and is also weakly phosphorescent.
