| Abstract: | The monumental tomb of Jefferson Page, an officer in the American Navy, was built in 1899 and is located in the Non-Catholic
Cemetery of Rome (Italy). This study presents complementary diagnostic studies characterizing the stone of the tomb and the
weathering and decay phenomena it has undergone. The monument is made of a single type of whitish marble, variously veined
and often covered with black patinas. Petrographic, isotopic and LA-ICP-MS analyses attribute the marble to the Carrara district.
SEM/EDS and microbiological analyses indicate that the black patinas are due to cyanobacterial autotrophic and fungin heterotrophic
colonization. Fourier-transform infrared spectroscopy revealed the presence of organic material on some portions of the tomb,
due to undocumented restoration carried out with a mixture of marble powder and a polyester resin. |
