Environments

Sedimentary environments

Marićite occurs in phosphatic nodules in sideritic ironstone, sometimes alone, and sometimes associated with barićite, kulanite, lazulite, ludlamite, penikisite, quartz, siderite, pyrite, wolfeite, apatite, wicksite, nahpoite, satterlyite and vivianite. The marićite may have inclusions of ludlamite, quartz and vivianite (HOM, Mindat, Dana).

Localities

At the type locality, Big Fish River, Dawson mining district, Yukon, Canada, marićite occurs as grains in nodules from shale, associated with quartz, ludlamite, vivianite, pyrite, wolfeite, an apatite-group mineral, a varulite-group mineral and satterlyite (CM 15.396-398). Also in veined phosphatic ironstone (Mindat) associated with lazulite, childrenite and siderite (Dana).
