Age and sources of detrital zircons from Jurassic conglomerates of the Strelka Depression (northern frame of the Mongol-Okhotsk fold belt)

Cover Page

Abstract


The article presents the results of U-Th-Pb geochronological studies of clastic zircons from cement of the Jurassic conglomerates of the Strelka Depression extended in a sublatitudinal direction along the border between the southern margin of the Selengino-Stanovoy Superterrane and the Mongol-Okhotsk fold belt. It has been shown that Paleoproterozoic and Neoarchean zircons dominate in the conglomerate cement. This indicates that the main demolition of the material to the sedimentation basin was carried out from the southeastern frame of the North Asian Craton (from the north in modern coordinates). In our view, the Strelka Depression formed after the completion of orogenic processes associated with the formation of the Mongolo-Okhotsk structure.
