A small ancient mine situated around 2.5 km NE of the town of Lavrion, close (less than 1 km North) to the famous "Km 3" site. Mineralisation occurs from the weathering of Pb-Zn ores (galena, sphalerite), and includes a very interesting assemblage of Cd-minerals (type locality for niedermayrite) and a suite of interesting chlorides and sulfates.
67 valid minerals. 5 (TL) - type locality of valid minerals.
This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

145 - 201.3 Ma
|Jurassic intrusive and metamorphic terranes|
Age: Jurassic (145 - 201.3 Ma)
Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
Lithology: Intrusive and metamorphic terranes
