The photograph shown antitetic domino-microfaults in the so called Parvenets two-mica plagiogneisses which consitute the basement of the Trakia unit, northern Central Rhodopes, Bulgaria. The antitetic domino-microfaults indicate top-o-the-left (top-to-the southeast) sense of shear. These faults are formed during the third deformation phase in the tectonic evolution of the area – a stage of brittle to brittle-ductile strike-slip faulting and south-vergent trusting. During this stage some parts of the Trakia unit overtrusted the Late Oligocene sediments from the northernmost slopes of the Central Rhodopes. Near Parvenets village in the area of Plovdiv.
