Iso-orogeosigmeta and iso-orogeoserie in the calcareous ridge of Mount San Vicino (central Apennine). An integrated detailed geobotanical and geological study is here presented in order to put in evidence the strict tie between vegetation series and detailed lithologies belonging to the umbrian-marche sequence, that appear in different bioclimatic belts, in a limited territory, characterized by a well defined geological history. With this aim, the M. San Vicino’s Marche ridge has been taken into consideration, that a recent published study indicated as a representative example of central Apennine phytocoenotic and sinphytocenotic diversity. The lithological formations that appear to the nucleus of the macro-anticlinalica structure, from the lower mesotemperate to the lower supratemperate belt have been investigated.These formations are represented, from the most ancient to the most recent term, by Calcare Massiccio, Calcari diasprini umbro-marchigiani and Maiolica, each one having mineralogical and lithological characteristics, qualified for specific vegetation series and geosigmeta.
