Study of vulnerability and characterization of stone columns from Seville (Spain)

Abstract

The aim of this research was the characterization of archeological columns of different periods found in Seville (Spain) by studying their conservation degree and vulnerability situation. This work is part of a project which is being carried out in the Historical City of Seville and consisting on the analysis of the risk and vulnerability in Historical Centers. In the city of Seville, a large number of these columns could be recognized as reused in the cathedral, inside and outside churches, in civil Monuments and as a reinforcement of building corners in the city. Marble, limestone and granite columns have been investigated in order to carry out the mineralogical and petrographical description of the stones and to evaluate their conservation degree and vulnerability to environmental hazards. Several analytical techniques have been employed to determine composition of specimens and their weathering forms.
