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).
