EXPLORATION OF GAMBURTSEV SUBGLACIAL MOUNTAINS (EAST ANTARCTICA): BACKGROUND AND PLANS FOR THE NEAR FUTURE
The Gamburtsev Subglacial Mountains (GSM), located in the central East Antarctica, were discovered by the Soviet team of the 3rd Complex Antarctic Expedition in 1958-1959. The GSM has highly dissected Alpine topography reaching maximum elevations of 3000 m. The mechanism driving uplift of the young-...

The Gamburtsev Subglacial Mountains (GSM), located in the central East Antarctica, were discovered by the Soviet team of the 3rd Complex Antarctic Expedition in 1958-1959.

With only limited constraints available on the topography, geology, and lithospheric structure, the origin of the GSM has been a matter of considerable speculation. The latest interpretation suggested that the GSM were formed during Permian and Cretaceous (roughly 250-100 Ma ago) due to the combination of rift-flank uplift, root buoyancy and the isostatic response.
