p.120: Many sills and small magma bodies of andesitic composition intruded the Lower Orobic Imbricates and the Upper Orobic Nappe. Because of their notable size, two of these subvolcanic bodies are depicted on the tectonic map, one near Gandino and the other east of Albino (Colle Gallo), both northeast of Bergamo. They are associated with normal faults and cut earlier thrusts. Intrusion ages around 40 Ma and geochemical analyses suggest a close relationship with the earliest Adamello intrusion stages (D’Adda et al. 2011).
