Description:
The results of geological and geomorphologic surveys on the salt marsh of Ganzirri (Pantano Grande), combined with
geophysical researches and historiographical data, are reported here to define the genesis of the marsh and to evaluate the physical
factors that influenced its recent evolution. The genesis of the Pantano Grande may be due to a state of equilibrium reached between
differential lowering of the coastal plain, confined by normal faults, and generalized chain uplift. In particular, two normal faults are
considered: the first borders the northern shore of the Pantano Grande, and the second bounds the Ionian coastal plain towards the
south. Concerning the recent evolution of the Pantano Grande the importance of the sterile conglomerate outcrop, which borders
the Ganzirri coastal plain, is stressed. The conglomerate is interposed between sediments that define the Pantano Grande basin, and
the Ionian Sea, and influenced the water exchange between the marsh and the sea. Before the excavation of two canals that link up
the Pantano Grande with the sea, the conglomerate, limiting the spread of benthic species, has definitively affected the ecological
structure of the original marsh.
