[snip] In our paper [”An anthropogenic origin of the ‘Sirente crater’, Abruzzi, Italy”, by F. Speranza, L. Sagnotti and P. Rochette, Meteoritics & Planetary Science 39, Nr 4, 635-649 (2004)] we report the results and the conclusion of a specific study on the morphological and geological characters of the Sirente plain, on the comparative analysis of several lakes from neighbour Abruzzi highlands which are very similar to the Sirente lake, and on geophysical and geochemical analyses carried out on soils and paleosols from Sirente and other Abruzzi localities.
