BROKEN SPELEOTHEMS AS INDICATORS OF TECTONIC
Stanka ŠEBELA - (37/1,2008)
In karst caves broken and non-ideal speleothems are very widespread.
Mostly they develop because of the instability of the
ground due to its composition (loose sand or loam). The presence
of recent cryoturbation in some caves in higher altitudes
suggests that some ancient breaks of the speleotheme can be
caused by ice in the cave. And we also have some good proofs
for recent and past tectonic activity in karst caves. In many
cases it is very difficult to determine the real reason for broken
speleothems, because several reasons could be interacting. In
Postojna Cave some examples related to tectonics were studied.
