Purga di Bolca (Monte Purga di Bolca), Vestenanova, Provincia di Verona, Veneto, Italia


Zeolites in altered basalt at the foot of Monte Purga di Bolca (933 m a.s.l.).

Basalt at Monte Purga di Bolca (a volcanic neck which forms a characteristic conical hill) hosts mantle peridotite xenoliths. These ultramafic xenoliths mainly show porphyroclastic textures, with large olivine (forsterite), up to 2 mm, and subordinate orthopyroxene porphyroclasts that set up in a fine-grained (100–400 μm) matrix formed mainly of olivine. The olivine porphyroclasts are strained with undulose extinction, whereas the olivine neoblasts are unstrained. Orthopyroxene shows exsolution lamellae of Ca-rich pyroxene. Fine (0.4–0.6 mm) interstitial clinopyroxene grains are partly or totally spongy. The spinels are present as brown grains with reaction rims at the contacts with spongy clinopyroxene and olivine.


Note: "purga" is the name locally given to a landform with a distinctly conical shape.
