Wulfenite with Mimetite on Limonite.
Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico
The Wulfenite in the center is 2.0 mm and shows a very nice growth zoning. Wulfenites from Ojuela often show growth zoning, but the zoning in this specimen is very interesting as one can clearly identify the different growth-layers in the crystal.
