Maricite

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.
