Composition and age of rocks from the H. Miller Seamount (Marie Byrd Mounts, Amundsen Sea)
This work is devoted to results of the joint Russian-German geodynamic studies carried out in the West Antarctic (areas of the Amundsen Sea, the Southern Ocean, the Marie Byrd Seamounts, and the foot of the Marie Byrd Land continental slope) during cruises 18/5a and 23/4 of R/V Polarstern in 2001 an...

This work is devoted to results of the joint Russian-German geodynamic studies carried out in the West Antarctic (areas of the Amundsen Sea, the Southern Ocean, the Marie Byrd Seamounts, and the foot of the Marie Byrd Land continental slope) during cruises 18/5a and 23/4 of R/V Polarstern in 2001 and 2006. Material collected on the Hubert Miller Seamount (Marie Byrd Seamounts) attests to relict continental appearance of rocks. This suggests heterogeneity of the Amundsen Sea floor and its formation through a spatiotemporal combination of destruction of the continental crust, progressive thalassogenesis (oceanization-taphrogenesis), and rifting, as opposed to spreading origin.
