Opalized horizons in Thrace and Limnos could represent silica sinter deposition from alkali or neutral geothermal fluids [, Finally, gem-quality smithsonite in the supergene oxidation zone of the Lavrion/Attika carbonate-replacement deposit, was formed as a result of reactivity of carbonate minerals with acidic, zinc-rich solutions, derived from the destruction of sphalerite [, All Greek corundum, especially the vivid-colored varieties, are translucent to opaque, suitable for cabochons (, As such, the Trikorfo locality can be regarded as a promising area for the exploration of transparent, facetable gemstones.
