Geology and Origin of Supergene Ore at the Lavrion Pb-Ag

Minor exploitation and processing of iron ore in an-cient times took place during the classical era. The clamps and dowels of the Erectheion (Acropolis, Athens) as well as various tools necessary for exploration and exploitation of the ores at Lavrion were made of iron processed locally ( Conofagos & Papadimitriou, 1981 ). It is also possible that large amounts of iron were Original …

Origin of High-Grade Iron Ores at the Thabazimbi Deposit

Iron oxides (martite, microplaty hematite) present in these low-grade ores are texturally indistinguishable from those in the associated high-grade ores, ie ore formation is genetically associated with carbonate metasomatism. Microthermometric studies of fluid inclusions in sparitic carbonates and rare megaquartz reveal their hydrothermal origin. Two compositionally distinct …
