This paper attempts to show the relationship between joints observed in flysch formations field and microfracture fabrics invisible naked eye hand specimens. Ultrasonic measurements demonstrate that intensity orientations of domains “memorised” by rock specimens are associated with historical stresses within mass rather than lamination. The spatial these microfractures have been measured, their dynamic-elastic properties found correlate orientation macroscopic joint sets measured field. elastic vary because sedimentary diagenetic processes occured during tectonic deformations rocks Podhale Synclinorium Poland. structural discontinuities detected ultrasonic can be perceived as an incipient phase already visible attributed situ residual stresses.
