Sabinaite (Na<sub>4</sub>Zr<sub>2</sub>TiO<sub>4</sub>(CO<sub>3</sub>)<sub>4</sub>) is a rare carbonate mineral. It crystallizes in the monoclinic crystal system as colorless to white prisms within cavities. It is more typically found as powdery coatings and masses. It has a specific gravity of 3.36.
It has been found in vugs in a carbonatite sill on Montreal Island and within sodalite syenite in the alkali intrusion at Mont Saint-Hilaire in Quebec, Canada.
It was first described in 1980 for an occurrence in the Francon quarry, Montreal Island. It is named after Ann Sabina (1930âÂÂ2015), a mineralogist working for the Geological Survey of Canada.
