Perama Hill is a high sulphidation deposit hosted by tertiary sandstones (Lescuyer J.L.et.al. 2003) and is located on the east margin of Petrota graben.Perama gold mineralisation is related the late Eocene-Oligocene volcanism in the Rhodope massif.Gold mineralisation is associated with a series of wide (>1,5m) to narrow (few cm) milky quartz-barite veins and stockwork veining in the vuggy silica block.Gold in microsized was also found disseminated in the surrounding altered (oxide mineralisation) epiclastic sandstones (Lescuyer J.L.et.al. 2003)

Geological Map of the Mirofillon area, scale 1:50 000. The map shows polygonal and selected linear geological information sourced from the published IGME 1:50000 scale map of Greece. Geological units are identified using the 1G-E vocabulary that may differ from that on the printed maps. Τhe original data were published in the frame of the program for the compilation of the Geological Map of Greece, scale 1:50 000. The geological mapping has been carried out by K. Manakos, during 1981-1983. Micropaleontologic determinations : Dr. V. Skourtsi-Koroneou. IGME licensing terms and conditions apply to external use of the data.

The digital geological map of Greece at 1:1million scale is composed of layers of polygonal objects depicting stratigraphic units and lines depicting faults. It has been created - in the frame of the One Geology Europe Plus project - from the 1:50 000 scale map sheets, using the One Geology Europe vocabulary terms to describe lithology & age of formations.
