Colle dello Spizzicatore, Allumiere, Distretto dei Monti della Tolfa, Roma, Italia
The Spizzicatore hill (Colle dello Spizzicatore) is partly occupied by a quarry, where the ignimbrite rocks are occasionally extracted for road construction and servicing. Several types of rocks occur in this pyroclastic deposit (known in literature as โtufi caotici"): there are fragments of ignimbrites which show a glassy groundmass with K feldspar (sanidine), labradoritic plagioclase, biotite, ortho- and clino-pyroxene as main phenocrystals. Other holocrystalline tephra have a syenitic appearance and are constituted by dominant K feldspar (sanidine) and plagioclase, with minor pyroxene and biotite; common accessories are rutile and zircon (Negretti, 1962).
Cordierite ha been found in blocks with a very fine-grained holocrystalline texture. Cordierite crystal cores often enclose euhedral spinel, ilmenite, and quartz, often coexisting with monazite and pyrrhotite droplets. The ignimbrite can include volcanic rocks in which one can find different minerals. The fine-grained matrix is composed of plagioclase, abundant graphite flakes, accessory minerals (ilmenite) and numerous vugs and vesicles coated with smectite group minerals.
