Indagini geofisiche e minero-petrografiche preliminari sulla vulcanoclastite di Carapelle Calvisio (L'aquila - Abruzzo)

Abstract

Geophysical and geopetrographic investigations have been carried out near Carapelle Calvisio and Castelvecchio Calvisio villages. The volcanoclastic deposit, 25 m in maximum apparent thickness, is made up of both volcanic products of an alkaline-potassic magmatism and other materials of different origin. The magnetic investigations evidenced 3 perturbing body, probably of magmatic origin, placed at a greater depth than the underlying sedimentary basement. The location of the body is related to a negative-positive anomaly in an area characterized by absence of magnetic anomalies. Geoelectric soundings showed the sedimentary basement at a depth of about 45 m. The investigations revealed that the magmatic products in this area can be related to a local volcanic activity.
