Sabinaite

Named for a mineralogist at the Geological Survey of Canada who played a pivotal role in the characterization of the mineral, Ann Phyllis Sabina Stenson. It can be found only in the Francon quarry in Montréal, Sabinaite’s type locality, and the Poudrette quarry at Mont Saint-Hilaire in Québec, Canada. Sabinaite occurs in vugs in silicocarbonatite sills at the Francon quarry and in cavities in a sodalite syenite in a gabbro-syenite complex at Mont Saint-Hilaire.

Sainfeldite

Named after Paul Sainfeld, who collected the initial type material and an Honorary Curator at the National School of Mines in Paris, France. At its type locality at the Sainte-Marie-aux-Mines in France, Sainfeldite occurs as a post-mine mineral that forms as the result of the reaction between carbonate gangue minerals with arsenic solutions. Sainfeldite can additionally be found in the Czech Republic, Germany, and Morocco.
