A Search for Sources of the Detritus of Ordovician Sandstones from the Sol-Iletsk Block (Ordovician-2 Borehole) Based on the First Data of the Geochemical and Lu/Hf Isotopic Systematics of Zircons

The primary isotope–geochemical and geochemical characteristics (by the TerraneChrone® technique) are presented for detrital zircons dated previously (U/Pb, LA–ICP–MS dating) from Ordovician sandstones (the Ordovician-2 borehole of the Sol-Iletsk block). The characteristics of the treated zircons were compared to the corresponding parameters of the complexes constituting the possible sources provinces.
