Mineralpedia Details for Agardite-(Ce)
Named as an analogue of agardite-Y which in turn was named in honor of Jules Agard, a geologist with the Bureau de Recherches Geologiques et Minieres in Orleans, France, and for the dominance of cerium over the other rare earth elements. Notable localities for Agardite-Ce include at the Majuba Hill mine in Nevada, USA, at the Clara mine and Neubulach in the Schwarzwald Mountains in Germany, at St. Hilary and Gwinear in Cornwall, England, at Laurion in Greece, and at Tsumeb in Namibia.
