Lomonosov Ridge,ncluding the abyssal Makarov Basin – on the other. As its morphology and internal structure indicate, it consists of three distinct segments. The shallowest (≤ 400 m) Canada-Greenland segment is composed mostly by felsic and metamorphic rocks (basic igneous – at the part facing Alpha-Ridge). In the妨碍议事 发表于 2025-3-27 05:53:10
Podvodnikov Basin,ea shelf from the south and by the Makarov Basin - from the north. Sea depth in the Podvodnikov Basin varies from 800 m to 2700 m in the same direction. The Podvodnikov Basin has a benched structure and is considered to be a part of the terraced continental slope..The seismic data divide the souther美丽的写 发表于 2025-3-27 11:35:24

Mendeleev and Alpha Ridges,essively seaward deepening bathymetric terraces demonstrate the morphological connection of the Mendeleev Ridge with shallow water regions of the Siberian-Chukchi continental margin. Seismic data reveal that the structure and stratigraphy of the Mendeleev Ridge are affected by intensive normal faultcyanosis 发表于 2025-3-27 20:56:08

Extensional Structures of the Central Arctic Uplifts Complex,stretching and attenuation of the continental crust is the principal factor dictating the tectonic evolution of this block and its two-phased HALIP magmatism. The most evident signs of the rift-induced strain, − systems of grabens and half-grabens, high-altitude and gently dipping normal faults – ar地牢 发表于 2025-3-28 03:05:27
Canada Basin,particularly with the use of two ice-breakers working collaboratively – has led to new seismic and sample acquisitions. These studies have revealed extensive non-oceanic basement beneath Canada Basin that coincides with proof of a central spreading axis and limited oceanic crust.

Pliocene-Pleistocene Sedimentation, Ma as 1–1.5 mm/kyr, rising slightly towards the shelf seas of northeast Russia. The rates also increase towards the Lomonosov Ridge: in its near-Greenland sector, the Brunhes/Matuyama transition was identified in the sediment core at 330 cmbsf, giving rates of 4.4 mm/kyr for the Brunhes chron..Rece切掉 发表于 2025-3-28 14:05:12
