Environments
Voudourisite is a secondary mineral formed from the
weathering of primary
hawleyite and greenockite.
Associated minerals include lazaridisite,
sphalerite, galena,
edwardsite, chalcanthite,
gypsum and greenockite
(HOM).
Localities
At the type locality, the Esperanza mine, Kaminiza mines, Km 3, Lavrion Mining District, Lavreotiki, East Attica,
Attica, Greece, voudourisite and lazaridisite are two
secondary minerals from the mine, new in 2012. This small
ancient mine is also the type locality of niedermayrite and
katerinopoulosite. Further associated minerals are
sphalerite, galena,
edwardsite, chalcanthite,
gypsum and greenockite. Both
voudourisite and lazaridisite form tiny clusters or crusts and
are among the latest to form in this paragenetic sequence. They are colourless or white, transparent to translucent,
with a white streak and vitreous lustre
(MM 83.551-559).
