Abstract

New data on the Jurassic deposits composition and section structure in the Central zone of the Polousnyi Terrane are presented. Arkosic composition of sandstones and the predominance of granites in the sources area was established by petrographic investigation. Volcanic rock fragments of various compositions, as well as synchronous pyroclastic material also were identified in these sandstones. U-Pb isotope dating of detrital zircons and derive maximum depositional age made it possible to revise the stratigraphic volume of Jurassic deposits exposed in the Central Zone and limit it from the Upper Bajocian to the Tithonian. The immaturity of the composition and the absence of reliably dated Hettangian-Aalenian deposits indicate a new cycle of sedimentation and contradicts the existence of a single Verkhoyansk passive margin in Triassic-Jurassic time.
