Formation of Mn-skarn Ores at Thapsana Mines, Paros Island, Attico-Cycladic Metallogenetic Massif, Greece
Mn-skarn ore deposits are relatively infrequent worldwide. A typical example of a Mn-skarn in the Attico-Cycladic Metallogenetic Massif is located at the mining area of Thapsana, Paros Island. The skarn occurs adjacent to the Thapsana, highly sericitized, biotite-garnet-tourmaline-lepidolite leucogranite apophyses of the Paros granitoid and related pegmatites and aplites The Mn-skarns orebodies occur as lenses and NE-trending veins hosted in the Cyclades Blueschist Unit (CBU) marbles and intercalated calcic schists. They comprise two discontinuous paragenetic zones (with widths of ≤ 10 m): A zone that contains vesuvianite, Mn-enriched salite to johannsenite-diopside and spessartine with cores enriched in grossular component (Sps ~75 Grs ~15 ), placed close to the Thapsana leucogranite, and a zone of grossular (Sps ~85 Grs ~5 ), actinolite to Mn-cummingtonite (with Mn ~ 0.6 apfu) and phlogopite more distal from the leucogranite. The Mn-skarns are crosscut by later WNW-to W-trending veins filled with Ca-K-Mg-bearing pyrolusite, manganite, rhodonite and rhodochrosite, carbonates, hydroxylapatite and johnbaumite. The Mn-ores
