Verrucano Lombadro

Description

The Verrucano Lombardo (Upper Permian; Assereto & Casati 1965; Sciunnach 2001), consists of pebble ortho- and paraconglomerates, coarse-grained sandstones and micaceous siltstones (Fining Upward sequences). Pebbles are mainly rounded volcanic followed by subangular quartzites and minor metamorphic rock fragments. Typical is the wine red colour widespread whereas greenish reduction spots are observed only locally. Its facies architecture is characteristic of the alluvial fan-braidplain sediments.
