Deposit clan (type): Iron Skarn-type
Deposit (sub) types: big lenses and masses of hematite ore and limonite, containing 44 % Fe, some Mn and 0.05 % S, occur in calcareous rocks; magnetite veins up to 7 cm thick in associated quartzites and schists ; Reference: Zitzmann, A., 1977: The Iron Deposits of Italy; in The Iron Ore Deposits of Europe and Adjacent Areas: Explanatory Notes to the International Map of the Iron Ore Deposits of Europe, 1:2,500,000 (Text and Figures), Edited by Walther, H.

Deposit status: past producer; Size category: unknown; Status comments: one of the old Elba mines exploited since 2500 years ago; Rio Albano hematite-limonite ore mined by open pit; total ore production in Elba estimated at 50 Mt and resources of some 26 Mt
Geologic province: Alpine Orogen
Geologic subprovince: Apennines
Geologic district: Northern Apennines
Deposit object located: centre-deposit on surface
Commodities: Fe
Mineralization styles: irregular bodies; massive; veins
Geological ages: Late Miocene (mineralization)
Late Miocene (related magmatics)
Tectonic setting: continental unstated-unqualified; extensional; Formal name: Late Miocene extension and related plutonism (related igneous rocks)
Coincident features: stratification in host sequence (carbonate strata of the host formation, thickened due to isoclinal folding, provide lithological control for mineralization); Coincident feature name: Complex III of Elba Island
Regional tectonic structure: shallow-dipping extensional slides of Late Miocene age with eastward transport (Capo Calamita, Terra Nera, Rio Marina and Rio Albano deposits transported with detachments) Tectonic structure name: Extensional Allochthons
Host rocks: (1) sedimentary; carbonate (Rhaetean carbonate overlying Permian Verrunaco clastics and Carboniferous shale); Depositional setting: carbonate platform; Metamorphic grade: greenschist
External host rock forms:cavernous limestone
Host rock protoliths:limestone (extensional allochthon transported with ore deposit 12 km to the east during Late Miocene); Host rock protolith name: Calcare Cavernoso Formation
Internal host rock structures:fine grained
Individual lithologies:limestone (cellular limestone lying unconformably on clastic Permian beds )
Host rock stratigraphy:Complex III of Elba Island
Related igneous rocks: (1) intrusive; granodiorite-tonalite-diorite suite (deposit genetically related to the intrusion); Initials: Monte Capanne granodioritic pluton; Magma series: calc-alkaline; Depositional setting: continental
Individual lithologies:granodiorite (Late Miocene pluton in the western part of Elba Island, related to the poorly exposed Porto Azzurro quartz monzonite to the east)
Metallogenic signatures: Fe
Alteration signatures: oxidation and supergene enrichment: limonite; What was altered: iron oxide ore
Mineralogy: (alteration): limonite
(mineralization): magnetite, hematite, pyrite
Deposit shape: zone of lensoid and irregular bodies
Qualified comments: (Applies to: mineralization) One of the old Elba mines exploited since 2500 years ago; Rio Albano hematite-limonite ore mined by open pit; total ore production in Elba estimated at 50 Mt and resources of some 26 Mt.
