Abstract
The strata-bound mineralizations of the Palaeocarnic Alps/Italy are characterized by a zonation of parageneses: predominating Hg-Cu sulphides in the west, ZnS in the centre, barite and fluorite in the east. They are bound to a palaeorelief of Devonian limestones transgressively overlain by Lower Carboniferous to Lower Permian clastic sediments. The mineralizations are largely caused by reworking protores (sulphides) or weathering of carbonates (barite and fluorite). The developing Devonian reef relief, karst cavities and faults acted as mechanical and geochemical traps. In situ remobilization and recrystallization did not affect the almost lithified limestones which do not exhibit significant dispersion halos of base metals or brines. This rather unusual type of mineralization cannot be prospected by lithogeochemical proximity indicators.
