Phyllosilicate - Monoclinic - Mica group member. Brittle - Dioctahedral. Al occupying the (M) octahedral positions with sub's of Lithium, Ca (or possibly Na) at the Interlayer spots, and hydroxyl at the (A) positions. Be and Al can replace Si at the (T) positions.

Rarely as good pseudohex. crystals, usually scaly or platy aggregates. Grayish pink to pink, but also yellowish. Occurs mainly with diaspore in contact metamorphic deposits (Bernard & Hrysl), also in chlorite schists (Mindat). Associated with corundum, diaspore, tourmaline, staurolite, glauphane, chlorite, and magnetite...in high aluminun deposits (Handbook of Min.).

Named after Dr. Luka Maric, a former professor of Mineralogy and Petrology at the University of Zagrep in Croatia. Maricite is a rare mineral that occurs in phosphatic nodules in siderite-rich ironstones. It can be found in localities in Canada, Antarctica, Germany, Greenland, and India. Associated minerals include ludlamite, vivianite, quartz, pyrite, wolfeite, apatite, wicksite, nahpoite, and satterlyite.

Named for its type locality in the Moon Anchor mine in Maricopa County in Arizona, USA. Maricopaite occurs only at its type locality and is found in hydrothermal lead-copper ore veins as coating and filling fractures within quartz. Associated minerals include cerussite, mimetite, fornaceite, phoenicochroite, duftite, chrysocolla, wickenburgite, calcite, fluorite, and quartz.
