Field data are used to describe fracture morphology and to determine fracture patterns in Mesozoic sediments of the Mikhajlovgrad Anticline within an Alpine-age folded belt. Tectonic stress fields are based on fracture patterns, which give orientations of the principal stress axes. The maximum principal axis was used in a vector trend analysis, showing the regional tendency of the orientation of this axis to follow dip directions. A descriptive model of fracture generation requires the existence of two stress fields, a tensile (creating joint set bc) and compressive (creating set ac and system hko), which should be repeated at least several times during tectonic evolution of the area. Fracturing is deformation in a brittle or quasibrittle medium with longitudinal cracks corresponding to the ac set. This study consisted of four phases: (1) field descriptions and measurements; (2) separation of fracture sets using stereographic projections; (3) construction of tectonic stress fields; and a (4) vector-trend analysis of principal stress axes.
