The Mt. Jouf structure (Carnic Prealps) is a typical Cretaceous fold verging to the south and cropping out at the margin of the Friuli Plain (“ ellipsoidal zone”), near Maniago. The observations carried out along the southeastern flank modified the tectonic interpretation which had been formerly given. These evidenced the Mesozoic limestones below, the presence of younger beds referred to Scaglia and Flysch formations of Paleogenie age. The fold therefore is overthrust southwards and the displacement...
The extension in eastern Friuli of two Assemblage Zones, which are outcropping in the north slope of the Goriziano Karst and in the Medea Mt., is examined. The paleontological units, based on microfossils, and concerning the "San Michele Mt. Limestones", are recognized in two wells drilled near Buttrio and Terenzano. These observations allow us to extend the paleogeographical conditions verified in the Goriziano Karst to all the eastern Friuli Plain.
The structural features of the S. Giorgio Jonico Cretaceous Horst, near Taranto, are described for the first time. The bordering faults of this structure, extending NW-SE or NNW-SSE, are evident on the SE flank, where some quarries cut the calcareous-dolomitic formation. Calabrian sediments pinched in the fractures prove that faults are due to displacement which occurred also during the Pleistocene.
In the Val Rosandra, near Trieste, two lithostratigraphic units are outcropping besides Quaternary formations: the "San Michele Mt. Limestones", here limited to the Paleocene-Lower Eocene, and the Flysch referred to the Eocene. Structurally, in the valley are present an asymmetric anticline, trending NW-SE, and some normal faults the chief of which, trending NNW-SSE, outcrops south of Santa Maria Church. The information obtained from two wells, 73 and 90 m deep, drilled for water researches in the...
