Calcite, Mimetite
Potosi Mine (El Potosi Mine), Francisco Portillo, West Camp, Santa Eulalia District, Mun. de Aquiles Serdan, Chihuahua, Mexico
Small Cabinet, 7.9 x 4.4 x 3.4 cm
I do not know whether to call this calcite on mimetite or mimetite on calcite. Whatever the case - what you have here are intergrown rhombs of calcite and balls of yellow mimetite! You can see the rust-hued accents from the limonite as well. A fascinating old Santa Eulalia combo specimen! 7.9 x 4.4 x 3.4cm
