    Aerinite (Ca4(Al,Fe,Mg)10Si12O35(OH)12CO3·12H2O)[1] is a bright yellow to light brown inosilicate mineral. It crystallizes in the monoclinic system and occurs as fibrous masses and coatings. It has a vitreous luster, a specific gravity of 2.48 and a Mohs hardness of 3.[2]

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]
