Abstract. The forms and petrographic composition of psephitic-sized core samples collected in the northern and northwestern parts of the Franz-Victoria Trough (80º 30,413′ N, 39º 17,371′ E, watr depth 160 м) from the research vessel (R/V) Akademik Tryoshnikov during the Transarctic-2019 expedition (stage 1) were studied. The bulk of the studied psephites are represented by non-rounded sharply angular samples or angular and ribbed with noticeable abrasion of the edges. Among the forms of psephites, isometric and disc-shaped varieties predominate. Elongated forms (plated-like and rodlike) are found in smaller quantities. The expected pattern of iceberg movement during deglaciation is described and the expected source area of psephitic material is established.

Keywords: psephite, Barents Sea, shape, roundness, deglaciation, Franz-Victoria Trough
