L’esistenza di grotte e morfotipi di modellamento marino
(terrazzi, falesie, solchi di battente, grotte) nei rilievi carbonatici
che cingono la città di Palermo documentano
chiaramente la presenza di antiche linee di riva attestanti
le diverse fasi di emersione della regione. L’Autore, dopo
un inquadramento geologico e morfologico del Geosito
Montagnola di Santa Rosalia, rileva gli aspetti del carsismo
e l’importanza paleontologica e archeologica del sito;
quindi, illustra la proposta per l’istituzione di un Parco
Culturale Urbano e tutti gli interventi connessi affinché la
suddetta area possa essere salvaguardata e usufruita per
scopi formativi e divulgativi. The Mesozoic carbonatic relieves surrounding the Palermo
Plain are characterized by notable morphologic
structures that belong to the cultural heritage of Sicily.
These shapes, that are relevant to the eustatic Pleistocene
oscillations and modeled by the sea, are represented
by terraces, seacliffs, wave-cut notches, old shores, cavities.
The Geosite Montagnola of Santa Rosalia is a carbonatic
isolated block, encircled by steep rock walls; it is recognizable
for the wide and marked sea terrace, delimited
by high and very sharp seacliffs in which various cavities
are developed.
After a geologic and morphologic setting, the Author emphasizes
the aspects of karst and the characteristics of
the paleontological and archeology patrimony. Moreover,
the Author illustrates the proposal for the establishment
of an Urban Cultural Park and interventions to protect the
area examined. The Park will certainly be very important
from different points of view: natural, landscape, speleological
and cultural. The closeness of the reserve to the
town of Palermo will also be an excellent tool to educate
people to respect nature.
