Deposition of tempestites in the eastern Rheic strait: evidence from the Upper Palaeozoic of Southern Tuscany (Italy)

  • Huber Engelbrecht
Article

Summary

The siliciclastic lithologies of the Poggio al Carpino Formation are described from a newly defined type locality: The sediments have been deposited in a shallowmarine, inner shelf and lower shoreface environment, characterized by a high dispersity of energetic levels. Due to its low palaeolatitude position (<20°S) near the southern coast of the E-W-striking Rheic Strait between Gondwana and Palaeoeurope, the depositional environment has been influenced by seasonal tropical gales. The bulk of the coarse-grained lithologies represents amalgamated proximal lag-type tempestites, containing reworked material from laminated siltstone- and shaleinterlayers (deposited during quiesent periods), older tempestites and parts of the stratigraphic substratum. Offshore bottom currents bypassed the outer shelf region and triggered turbiditic and olistostromatic input into the slope and extensional basin.
