Description
| - The Sr isotope data from amphibolites obtained by JANOUŠEK et al. (2008) confirm that low 87Sr/86Sr ratios in Moldanubian marbles (FRANK et al., 1990) cannot be caused by volcanic contamination. Also the interpretation of the low ratios in marbles with sedimentation in an isolated sea is problematic due to absence of a relevant source of unradiogenic Sr. The interpretation of more evolved Sr- and Nd isotope ratios in amphibolites as a result of crustal contamination (JANOUŠEK et al., 2008) is problematic mainly due to apparent import of Mg at the ?contamination?. Thus also the preference of the early-Paleozoic Nd model ages of ?uncontaminated? amphibolites (JANOUŠEK et al., 2008) is doubtful. Precambrian age of the Varied group still remains the most probable.
