Abstract

In Castafiar cave the surface of most of the speleothems present dissolution
and corrosion features. In touristic caves, this process has usually been related to
the acidification of the atmospheric moisture caused by C02 from the breath of
visitors. However, in Castafiar cave the process of corrosion has been also observed
in rooms that are not visited by tourists. Petrological studies were carried out in
the speleothems affected by surface corrosion in Castafiar cave. The results indicate
that this process occurs not only at present time, but over a period of thousands of
years, as evidenced by the presence of corrosion lines inside and on the surface of
the speleothems. All this and the fact that Castafiar cave recovers very quickly from
changes in the environmental parameters, indicates that the dissolution-corrosion
process is slow and hence it is not related to the presence of visitors.
