Abstract
The article presents the results of petro-geochemical and geochronological studies of granitoid fragments collected in terrigenous sediments in the junction zone of the Gakkel Ridge with the Laptev Sea continental margin of Eurasia during the special marine geological expedition "Arctic-2022". The Carboniferous-Permian age of the granitoids and the maximum proximity of their composition to the granitoids of Northern Taimyr were established. The sources of the studied rocks in the immediate continental frame of the Gakkel Ridge and the Laptev Sea could be granitoids that participate in the structure of the fold belts of Northern Taimyr and Severnaya Zemlya.
