I (Manuel Robbins) reported on a mineral from Mont Saint-Hilaire then known only under the temporary designation UK84. It has now been given the name Gaultite. It is a sodium zinc silicate hydrate. As reported in the book (see bibliography), fluorescence is bright green under SW. It was found as small colorless or mauve crystals to 0.05mm in a sodalite cavity at a contact between hornfels and sodalite syenite. (citation of Manuel Robbins)
