It crystallizes in the monoclinic system and occurs as fibrous masses and coatings. It has a dark, vitreous luster, a specific gravity of 2.48 and a Mohs hardness of 3. It is a low-temperature hydrothermal phase occurring in zeolite facies alteration of mafic rocks. Associated minerals include prehnite, scolecite and mesolite.[1] Its name comes from a Greek root "aerinos," meaning "atmosphere" or "sky".[3] References1. ^1 Aerinite.
