ABSTRACT
This paper traces the development of folding within a portion of the Krynica slice which is the innermost tectonic slice of the Magura nappe in Poland. Analysis of map-scale structures has been combined with studies of small-scale structures, mineral veins and diagenetic maturity. Five groups of small-scale structures: hydroplastic faults, deformation bands, joints, sandstone dykes and brittle faults have been studied. Results indicate that map-scale folding and thrusting as well as cross-fold jointing occurred in Paleocene-Eocene times during deposition of the strata involved. The folding and thrusting were completed when these strata were still poorly indurated.
The folding, thrusting and cross-fold jointing occurred simultaneously due to numerous permutations of the principal stress axes. The bulk of calcite mineralization was introduced into the strata involved after completion of folding. Still later, the entirely indurated strata were cut by brittle faults.
