Clastic rock (diamictite with ocraceous matrix and calcite cement, clasts with angular corners). Colour: grey with some yellowish hues. Mineral: clasts of Dolomia principale (Haupt dolomit), size from 0.05 to 1.0 m. Decay morphologies: roughening on clasts and matrix, soot deposition on cavities, sulphate skins formation. Geology: “Complesso di Poltragno”, subdivided in two units (Unità di Poltragno and Unità di Gré), including slope deposits and alluvial deposits (lower and middle Pleistocene). Quarry: near Castro (Bergamo province), on the mountain rising above the north-western shore of lake Iseo. Use: slabs with sawed face for cladding of residential and public buildings (Casa dei Giornalisti, G. Muzio 1936, Milan; Palazzo Vittoria, E. Frisia 1935, Milan). Besides, this conglomerate is employed today (i. e. the façade cladding on the new building of Università Bocconi, Grafton architects 2008, Milan).
