The main tectonic features of Apenninsky peninsula and Sicilies connected with a thermal stream

From the general reasons, it is possible to consider Apenninsky peninsula and Sicily kajnozojskoj orogenicheskoj as area. In this area located to the south from Padansky plain, four basic structural elements are allocated: forland, the advanced deflection and intermountain hollows of the Apennines (Apenninsky folded area and development area postorogennyh volcanic adjournment).

1. The area forlanda is combined karbonatnymi by breeds jury and a chalk (sometimes blocked transgressivnymi adjournment paleogenovogo, miotsenovogo and chetvertichnogo age); stratigraficheskoe the basis of this complex of breeds almost everywhere is presented evaporitami.

2. Areas of the advanced deflection correspond large postorogennomu grabenu which was formed in pozdnepliotsenovoe - chetvertichnoe time and is filled now by glinisto-sandy deposits. Intermountain deflections represent morfostrukturnye formations of the smaller sizes (they were generated in a final stage or after end orogenicheskogo a cycle); these deflections were filled with deposits during pliotsena and plejstotsena.

3. The Apenninsky folded area is combined by several allohtonnymi the sedimentary series consisting in basic from glin, mergelej, sandstones and limestones. Among these formations it is possible to allocate evgeosinklinalnyj a complex of breeds (a chalk - paleogen), miogeosinklinalnyj a complex (top trias - miotsen) and a complex of breeds miogeosinklinalyjugo a ridge (jura - a chalk). In the Kalabrijsko-Peloritansky zone these complexes include also crystal breeds which, probably, are connected with any central file. At last, in an external zone of the Apenninsky mountain chain are bared postorogennye the series consisting from mergelistyh, clay and sandy adjournment, places gipsonosnyh (bottom - top miotsen).
