The Liassic carbonate sequence outcropping on the M. Coro area was affected by extensional events causing its break-up and the sinking of blocks of marginal platform. The irregular relief was the site of gravitational slides along new formed fault-slopes. The movement took place along sub-parallel sets of planes during the Early Jurassic. Fragments of platform (Corna limestone) were therefore resedimented at the footwall of faults (megabreccias) or interbedded as olistoliths into the pelagic sequence (Medolo Formation) at different levels. The geological researches, extended outside the M. Coro area, give moreover evidence of the paleorelief: highs are located west- and north-wards (Teglie), lows along the well-exposed section of the Chiese River (South of Vobarno).

Abstract
The Liassic carbonate sequence outcropping on the M. Coro area was affected by extensional events causing its break-up and the sinking of blocks of marginal platform. The irregular relief was the site of gravitational slides along new formed fault-slopes. The movement took place along sub-parallel sets of planes during the Early Jurassic. Fragments of platform (Corna limestone) were therefore resedimented at the footwall of faults (megabreccias) or interbedded as olistoliths into the pelagic sequence (Medolo Formation) at different levels. The geological researches, extended outside the M. Coro area, give moreover evidence of the paleorelief: highs are located west- and north-wards (Teglie), lows along the well-exposed section of the Chiese River (South of Vobarno).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
