Abstract: 

E. Kozhoukharova, M. Ichev. Dynarnornetamorphism and pseudofossil effects in marbles and calc-schists of Lukovica Formation in Asenovgrad area. The study is scoped on the character and mechanism of late (Alpine) transformations of the amphibolite facies Precambrian rocks of Lukovica Formation in Asenovgrad area. Their irregular development depends on structural and lithological factors. Marbles and calc-schists are most strongly affected and turned into mylonites which visually resemble carbonate sediments and the traces of deformational tectonoclasts remaind of macrofossil imprints. Intrafoliation movements are of dominant role and as a result formed numerous low-amplitude shear zones of intensive dynamometamorphic transformations at different stratigraphic levels. The zones are structural and compositional, of destructive and constructive effect: brittle and ductile deformations, granulation and diaphthoritic crystallization of new mineral paragenesises in greenschist facies.
