speleothems lead to the last possible reason—seis-

presence of an underground river, to analyze samples
in remote parts of it;
4. Cave is a narrow cavern (sinkhole) draining a
considerable territory;
5. Deformed or fallen bodies lie on a stable hori-

effect.
Therefore,
to

analysis
of
deformed
speleothems
it
is
necessary to have the following elements:
1. The studied cave should be well protected from
negative anthropogenic interference—i.e., relatively
inaccessible and unvisited;
2. In the studied cave is found a sufficient number
surface,
which
excludes
their
secondary
redeposition;
6. The analyzed deformed specimens are calcified
to the floor (covered with calcite crust) or calcified to
an older generation of secondary formations—evi-
dence of the relative age of the event that caused the
deformation.
