Hydroterskite
Hydroterskite is a rare zirconium silicate mineral, related to terskite (hence its name), with the formula Na2ZrSi6O12(OH)6. It was discovered in the Saint-Amable sill near Montréal, Québec, Canada.[1] It is hydrous, when compared to terskite.[2] Chemically similar minerals include litvinskite and kapustinite.[3][4]
