2.3.1.4 Results
Structural investigations applied for rock formations
of different age (but within the Jurassic Period) allow
to differentiate the reconstructed tectonic stresses in
time. Table
2.2
shows diagrams of the reconstructed
tectonic stress fields for the sites of performed mea-
surements, which are related to a certain tectonic
phase of a global scale. This turned out to be the most
logical scheme when interpreting and comparing
reconstructions for the sequence of Jurassic lime-
stones of different age.
structural studies, indicators of displacements on the
joint and fault surfaces have been found—exception-
ally
well-preserved
tectonic
striations
covering
in
some cases surfaces of several square meters.
Reconstruction of the Tectonic Stress Fields Using
Tectonic Shear Joints
This study has been carried out following the method
of Nikolaev (
1977
), which has been already com-
mented. In the region studied, mass measurements of
joints have been carried out in four outcrops.
