[meteorite-list] Origin of Sirente “crater” (sag) disputed

[Paul]

An article in journal of Geophysical Research disputes 
the origin of the what has been called the “Sirente crater”.

The paper discussing this theory is:

Speranza, F., I. Nicolosi, N. Ricchetti, G. Etiope, P. Rochette, 
L. Sagnotti, R. De Ritis, and M. Chiappini (2009), The 
“Sirente crater field,” Italy, revisited. Journal of Geophysical
Research. vol. 114, B03103, doi:10.1029/2008JB005759
http://www.agu.org/pubs/crossref/2009/2008JB005759.shtml

They concluded:

“Our data show that the Sirente crater and the minor 
depressions are simply the results of human activity and 
karstic processes, respectively.”

An article that discusses this paper is:

Bondre, N., 2009, Geomorphology: Crater or not? Nature
Geoscience. vol 2, no. 3, p. 166.
