Environments
Lazaridisite is a secondary mineral formed from
the weathering of primary
hawleyite and
greenockite. Associated minerals include
voudourisite,
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 minerals, 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
secondary minerals form tiny clusters or crusts and are
among the latest to form in this paragenetic sequence
(MM 83.551-559).
