Chemical and biological weathering of an historical building: Reggio Emilia Cathedral
TLDR
In this article, the alteration of marble and limestone surfaces of the facade of Reggio Emilia Cathedral has been studied, and the impact of air pollution seems to prevail over natural weathering mechanisms, including biological processes.About:

TL;DR: The importance of oxalate in geomycology, biodeterioration, environmental biotechnology and bioremediation is discussed in this article, where salient information from environmental and applied research is drawn together to emphasize the importance of Oxalate.
Journal ArticleDOI
Factors affecting the weathering and colonization of monuments by phototrophic microorganisms
TL;DR: Monuments provide unusual niches for the growth of algal communities, as in the case of black sulfated crusts, or endolithic and hypogeal niches, where more specific processes and/or communities occur.
Journal ArticleDOI
Raman Spectroscopy of Natural Oxalates
TL;DR: In this paper, a comparative study of a suite of natural oxalates including weddellite, whewellite, moolooite, humboldtine, glushinskite, natroxalate and oxammite has been undertaken using Raman spectroscopy The minerals are characterised by the wavenumber of the CO stretching vibration which is cation sensitive.
Journal ArticleDOI
The origin of calcium oxalates on historical buildings, monuments and natural outcrops
TL;DR: In this article, the authors show that the oxalate patina on Roman imperial marble is due to the shallow penetration of the fungi hypae into the rock, and that this phenomenon is not masked by other weathering processes.

TL;DR: Education initiatives as to the communication of a health risk resulting from contact with pigeons and pigeon excreta should primarily be targeted at individuals who may be exposed to C. psittaci-contaminated dust, such as demolition/construction workers.

Wetting, deterioration and visual features of stone surfaces in an urban area
TL;DR: In this article, the deterioration of carbonaceous rocks in urban areas can be roughly classified in three kinds of feature patterns visibly distinguishable on the rock surface, and three different kinds of deterioration are described and interpreted in terms of the principal mechanisms leading to their formation.
Journal ArticleDOI
Airborne carbon particles and marble deterioration
TL;DR: In this paper, a series of analyses performed on the carbonaceous particles and on thin sections of sulfated layers show that these particles are probably the most important, if not the determinant, agents of the observed deterioration.

Weddellite on limestone in the Venice [Italy] environment.
TL;DR: This is the first report of a large deposit of weddellite (CaC2O4-2H20), the formation of which is still in progress, and the origins of its formation established.

Gypsum crusts and fly ash particles on carbonatic outcrops
TL;DR: In this article, a study of the alterations caused by chemical weathering on carbonatic outcrops in the South of France (near Marseille) has revealed the presence of gypsum crusts.
