The first results of UPb (LA-ICP-MS) dating of detrital zircons from the Upper Visean sandstones of the Solnechnaya Formation of the Southern Urals are presented. The studied zircons are predominantly of Ordovician and Cambrian ages. The main peak falls at the beginning of the Ordovician period (about 480 Ma), and the local peaks at the beginning of the Late Ordovician, the middle and the beginning of the Cambrian. Comparison of the obtained age distributions of detrital zircons from sandstones of the Solnechnaya Formation with the nearby formations of the Western and Eastern Urals showed that the source of detrital material could be the Early Paleozoic metamorphic, igneous and terrigenous rocks of the East Uralian Megazone.
