Blocks, rich in cavities, of dark grey calcareous breccia and yellowish limestone, at an elevation between 2850 and 2900 m, in the morainic deposits of Gran Zebrù Glacier. Calcite, which appears as scalenohedra up to 9 cm in length, is the main mineral and it is sometimes associated with oxidated cubic or cuboctahedral pyrite, dendritic manganese oxides and pink octahedral fluorite (Bedognè et al., 2006). Always in this area, white fibrous mammillary concretions of aragonite were found by P. Sigismund (Gramaccioli, 1962).

Calciphyre blocks. The mineral assemblage (clintonite, fassaite, spinel, epidote, aragonite, calcite, chlorite, biotite and chalcopyrite) of some blocks, found also at Vedretta di Solda (Suldenferner) (see http://www.mindat.org/loc-123257.html) in Solda Valley (South Tyrol), seems to indicate the same origin, i.e. an outcrop probably located in the area of Passo della Bottiglia (Königsjoch) (see http://www.mindat.org/loc-259789.html) and in any case along the watershed between Cedec and Solda valleys (Tomasi, 1940 and 1950; De Michele, 1968; Scaini, 1972). Therefore, these minerals are listed here and at the two above mentioned localities.
