Localities
At the type locality, the North Mesa Mine group, Temple Mountain, San Rafael Mining District, Emery county, Utah, USA, the
host rock is conglomerate. Anorthominasragrite occurs as
microcrystalline crusts and efflorescences in a silicified tree that has a rim of coal around it that is 6–25 mm thick.
Associated minerals include orthominasragrite,
minasragrite, bobjonesite,
szomolnokite, sulphur,
rozenite, kornelite and
