Die durch Gesteins-Tropfen an der Unterseite der antarktischen Platte verursachte Kontinentalhebung hob die Landmasse über einen Kipppunkt hinaus, ab dem Eis wachsen und bestehen bleiben konnte.

Mantle waves and tectonic stretching lofted polar mountains into a deep freeze

A rift event set off a domino effect of geologic processes that created conditions ripe for Antarctica’s glaciation, a new study suggests.

Why Antarctica became glaciated ∼34 million years ago (Ma) remains debated, as relatively warm climates and sea temperatures appear inconsistent with ice sheet formation. Although a critical decline i...

Seismic data from the Turkana Depression in East Africa show that areas of thinned lithosphere are not necessarily persistent weak zones where extension and magmatic provinces will develop.

Reconstructing chemical variations of magma during rifting is challenging due to the heterogeneous mantle sources of the melt and different evolution pathways that magma potentially takes. Therefore, ...
