Note: D index, preceding the numbers of all samples and used in the text of the paper and in Fig.2 is omitted herein. La_N/Yb_N, La_N/Sm_N, Gd_N/Yb_N and Eu/Eu* are chondrite-normalized according to [62].

The analyses were made by D.V. Avdeev on the ISP mass spectrometer ELAN DRC II (perkin, Elmer, USA) in the laboratory of physical-and-chemical methods of investigation of the ITiG, FEB RAS.
