Esperanza Mine, Kaminiza mines, Km 3, Lavrion Mining District, Lavreotiki, East Attica, Attica, Greece

Largest Crystal Size: 70 μm

SEM micrograph (BSE mode) of black lustrous, pseudo-octahedral hetaerolite crystals (SXRD- and EDS-analysed; practically pure) on a fibrous Mn oxide (probably pyrolusite according to EDS data).
The void containing the hetaerolite crystals was coated by a layer of very thin, fibrous grey coronadite crystals (EDS-analysed) which grew before the hetaerolite.
