“…На шельфе хребет продолжают образованные горстами острова Новосибирского архипелага: Котельный, Бельковский, Столбовой. Поперечные профили на шельфе через эти острова и в океане через хребет Ломоносова практически аналогичны и составляют единую структурную зону [5]. В других районах такая особенность структур-ного рисунка не всегда выдерживается.…”

“…По сейсмическим и магнитометрическим данным под осадочным чех-лом этой котловины и поднятия Менделеева лежат покровы базальтов валанжин-барремского возрас-та. В котловине вулканогенно-осадочные толщи за-нимают весьма обширные площади и имеют мощ-ность на ее бортах около 500, а в центральной части до 1500-2000 м [5]. Возраст пород извлеченного при бурении керна и образцов базальтоидов, ото-бранных из эскарпов поднятия Менделеева, свиде-тельствует о нескольких вулканических импульсах, которые возникали на протяжении поздней перми -триаса и практически всего мела [13; 4].…”

The Laptev Sea in the Siberian Arctic represents a unique tectonic junction of an active spreading ridge, the Gakkel Ridge in the Eurasian oceanic basin, with the Siberian Arctic continental margin. New long-offset seismic profiles acquired in recent years provide a reliable basis for deciphering the structural and seismic stratigraphic characteristics of the Laptev Rift System. The tectonic development of the Laptev Shelf represents a sequence of four phases controlled by relative plate movements: (1) intense brittle normal faulting (an initial rifting or stretching phase) affected the entire shelf in the Late Cretaceous(?)–Paleocene(?); (2) a thinning/exhumation phase resulted in exhumation of the lower continental crust and probably upper mantle in the western part of the rift system – this phase is inferred to have occurred during the Late Paleocene to Early Eocene, preceding and accompanying continental break-up in the Eurasia Basin; (3) a stalled rift phase characterized by either a dramatically reduced rate of extension, or a non-extension/compression regime controlled by major reorganization of the plate movements – the onset of this fourth phase is inferred to coincide with the initiation of seafloor spreading in the southern Eurasia Basin at around 53–50 Ma; and (4) reactivation of the rifting in the mid-Miocene (a second rift phase).
