The first results of U/Pb isotopic dating (LA ICP MS) of detrital zircons from sands from the Middle Cambrian Sablinka Formation, Upper Cambrian Ladoga Formation, Low Ordovician Tosna Formation, and calcareous sands from Syas' Formation (Sargaevskii horizon of the Upper Frasnian) from Baltica-Ladoga Glint (BLG) of the Southern Ladoga area are presented. The obtained ages of detrital zircons span the intervals 492.7 +/- 5.1-3196.4 +/- 5.1 Ma (Sablino Formation); 577.9 +/- 7-2972.6 +/- 13.4 Ma (Ladoga Formation); 509.4 +/- 8.5-3247.6 +/- 10.1 Ma (Tosna Formation); 451.1 +/- 14.7-2442.2 +/- 6.9 Ma (Syas' Formation). A comparison of the obtained isotopic ages of detrital zircons to ages of crystalline complexes composing the Kola-Karelian, Svecofennian, and Sveconorwegian domains of Baltic Shield and Pre-Uralian-Timanian structures of Subpolar and Polar Urals and basement of Pechora Basin was carried out. It is proposed that the Middle Paleozoic sedimentary basin accumulated Upper Frasnian rocks of Syas' Formation. The basin ranged northward from the present-day BLG and occupied the eastern part of the Baltic Shield.
