Ages and intensities of metamorphic processes in the Batočina area, Serbo-Macedonian Massif Kad. Balogh /
The rocks of the polymetamorphic complex of BatoCina were studied by the Rb/Sr and K/Ar isotopic methods in order to determine the age and intensity of metamorphic phases. Rb/Sr data of eight whole rock samples are arranged along two regression lines defining model ages of 709±51 Ma and 488±19 Ma. T...

| Tartalmi kivonat: | The rocks of the polymetamorphic complex of BatoCina were studied by the Rb/Sr and K/Ar isotopic methods in order to determine the age and intensity of metamorphic phases. Rb/Sr data of eight whole rock samples are arranged along two regression lines defining model ages of 709±51 Ma and 488±19 Ma. The older age is chronologically meaningless since RL-I is a mixing line. The younger datum of 488±19 Ma gives th age of the oldest recognized metamorphism. Several K/Ar ages on amphiboles indicate Hercynian age, while on the basis of K/Ar ages on muscovite and K-feldspar 0.30±0.13 mm/year uplift rate was obtained for the time interval from 150.6 Ma to 127.3 Ma. |
