The U-Pb age dating of detrital zircons from Upper Jurassic-Lower Cretaceous deposits of Stolbovoy Island (New Siberian Islands)

The results of the U-Pb (SIMS and LA-ICPMS) age dating of detrital zircons from Upper Jurassic-Lower Cretaceous sandstones of Stolbovoy Island show that these deposits contain zircons of a wide age range, from Archean to Lower Cretaceous. Precambrian gneisses and granites, as well as Late Paleozoic and Mesozoic plutonic and volcanic complexes, are considered to be the main source areas of clastic material of Upper Jurassic-Lower Cretaceous formations of Stolbovoy Island. The U-Pb age dating of detrital zircons from sandstones without making a selection on any basis yields the most complete information about source areas of clastic material in a sedimentary basin. In some cases the data on euhedral (idiomorphic) and transparent zircon crystals can be useful to clarify the lower age boundary of sedimentation.
