Les scapolites , dont le nom provient des mots grecs signifiant « bâtonnet » et « pierre », constituent une catégorie de minéraux silicatés qui forment des roches et sont composés de silicate d'aluminium, de calcium et de sodium, ainsi que de chlore, de carbonate et de sulfate. Les deux principaux pôles de ce groupe sont la méionite, de formule Ca₄Al₆Si₆O₂₄CO₃, et la marialite, de formule Na₄Al₃Si₉O₂₄Cl. La silvialite, de composition (Ca,Na)₄Al₆Si₆O₂₄(SO₄,CO₃), est également reconnue comme appartenant au groupe des scapolites.
Provenant de l'ancienne collection de roches et minéraux de Schneider, Poway, Californie, États-Unis
