Within the Italian national geological mapping project (CARG, geological maps at 1:50.000 scale) SUO-CAR service of ISPRA is performing the sheet 348 "Antrodoco". Several problems about stratigraphic relations and structural setting has been surveyed involving Latium-Abruzzi carbonate platform (Nuria-Giano-Gabbia-Calvo mountains) with respect to slope deposits of transition zone of Umbria-Sabina and Gran-Sasso basin.

To calculate stress tensor parameters, inversion method by ANGELIER (1984, 1990) has been used. Stress analysis has been carried out with no assumption concerning the orientation of fault planes relative to stress axes, so that reactivated faults are taken into account as well as newly created ones, unlike Anderson's model in which conjugate fault systems are supposed.

Abstract
Within the Italian national geological mapping project (CARG, geological maps at 1:50.000 scale) SUO-CAR service of ISPRA is performing the sheet 348 "Antrodoco". Several problems about stratigraphic relations and structural setting has been surveyed involving Latium-Abruzzi carbonate platform (Nuria-Giano-Gabbia-Calvo mountains) with respect to slope deposits of transition zone of Umbria-Sabina and Gran-Sasso basin. Analysis was carried out by measuring structural elements and collecting them in two main datasets. Dataset A nearby "Cava di Sabbia" just north of Termine village, dataset B nearby "Cava di Pietrisco" SE of Piana di Cascina (Fig. 1). To calculate stress tensor parameters, inversion method by ANGELIER (1984, 1990) has been used. Stress analysis has been carried out with no assumption concerning the orientation of fault planes relative to stress axes, so that reactivated faults are taken into account as well as newly created ones, unlike Anderson's model in which conjugate fault systems are supposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
