Wodginite
Origin: Tanco Mine, Bernic Lake, Manitoba, Canada
Sample size: 5.5 x 3.5 cm specimen of
quartz hosting crystal masses of wodginite
This is a lustrous, fully terminated crystal of the rare mineral wodginite.
The specimens from this find, made in the 1980's, were unusual in that the
cores of the specimens were severely weathered
cassiterite which provided the lattice for the epitaxial development of
the subsequent wodginite phase.
Origin: Jaboti Mine, Sao Geraldo do Baixio, Minas Gerais, Brazil
Sample size: 3 x 1.6 x 0.6 cm (top), 2 x 1.7 x 0.6 cm (2nd row), 2.5 x 1.5 x
0.5 cm (bottom)

Wodginite grwon epitaxial on a decaying
cassiterite that is now barely present
Origin: Lavia Jabuti, Galileia, Minas Gerais, Brazil
Sample size: 3.1 x 1.7 x 0.7 cm
Origin: Linopolis, Minas Gerais, Brazil
Sample size: 1.6 x 1.1 x 0.6 cm
This is a razor-sharp, lustrous wodginite specimen. Surprisingly, it turns out
to be a thick coating of epitaxial wodginite that overgrew a decaying
spindle of internal
cassiterite, now almost vanished.
