Over 250 small bodies of acid, dike-like rocks, cross-cut and/or follow the main metamorphic foliation in the Northern part of the Sebes Massif. Their spatial distribution suggests a close relationship with the Cărpiniş-Cāpălna formation, also called "the Răşinari Shear-Zone? (RSZ). This paper presents the results of the microscopic study of one of these bodies, situated on the Sebeş valley, at about 3 km south from the Căpālna locality. The microscopic study revealed the presence of different small xenoliths, the recurrent zoning of plagioclase and the digestion of quartz. These features suggest that magma generating the studied petrographic body suffered contamination and even possible assimilation during its ascent, these processes modifying the composition of the melt during crystallization. The spatial relationship with the RSZ suggests that the emplacement of the bodies was structurally controlled and possibly even generated by the activity of the shear zone.
