19460: Galena, Wulfenite, and Mimetite -
$14 Ojuela Mine, MapimÃ, Mapimà Municipality, Durango, Mexico Small cabinet - 6.2 x 5.6 x 3.8 cm 352 grams Specimen status: Reserved What does Reserved mean? Send an email with specimen number to order Pockets and faces of a galena matrix
host several patches of mimetite and wulfenite. The
mimetites range from yellow-green botryoidal crusts to
yellow-brown crystals, these reaching about 2 mm. The
wulfenite is seen as opaque, tabular crystals, some of
which have a sandwich-like appearance (darker orange brown
interior surrounded by two lighter exterior layers) as
well as elongated crystals tapering towards truncated
points. Interesting not only for the morphology of the two
oxidized lead species, but also for the association (the
mimetite and wulfenite are most likely alteration products
of the galena). Not the prettiest Ojuela Mine
specimen out there, but certainly mineralogically
interesting.
