Abstract

Economic concentrations of bauxite, barite, fluorite and ores of iron, lead, and zinc were investigated in karst formations in Sardinia; they occur in addition to the known strata-bound and vein-type deposits of this major mining region. Three main periods of karst development and karst ore accumulation are recognized: the earliest of Cambro-Ordovician age, a second one of post-Hercynian age; the last of Alpine and post- Alpine age. Reworking of earlier karst ore was observed in different localities and took place during different periods.

A Hercynian granite intrusion has locally converted some karst fillings into skarn. Details on the ore sedimentation in the karst of different periods and areas are pre-sented on all for scales (regional, mine, hand-specimen, and mineral or microscopic).
