Description | Mimetite, Pb5(AsO4)3Cl (lead chloroarsenate), is so called because it resembles pyromorphite. It occurs in pale yellow or brownish hexagonal crystals. Mimetite does not form well shaped crystals often and especially of the green color. It usually is found as a botryoidal crust, a sparkling cauliflower aggregation or as minute spike-like crystals. |
