Aug 6, 2024 · The implications. The mechanism of plateau formation found here is similar to that by which the early continents on Earth — the cratons — are believed to have formed, suggesting that the ...
Aug 14, 2024 · Researchers said on August 2, 2024, that both Venus tesserae and early earthly continents on Earth could have formed through similar processes, even though Venus does not have plate tectonics, the ...
Oct 1, 2018 · The model also sets the stage for formation of continents outside a plate tectonic regime. Venus' surface has the potential to preserve a record of mantle flow unaltered by plate tectonics. Coupled evolution of the Artemis superstructure and Ishtar Terra might provide a blueprint of past mantle flow and continent formation.

Aug 2, 2024 · Using high-performance computer simulations and data from the Magellan spacecraft, researchers modelled the formation of Ishtar Terra, Venus’ largest plateau. The results suggest that Ishtar Terra and other tesserae may have risen from the planet’s hot interior through a process similar to the formation of Earth’s cratons – the ancient cores of our continents.
Oct 26, 2023 · The new paper posits that this wasn’t always the case. To account for the abundance of nitrogen and carbon dioxide present in Venus’ atmosphere, the researchers conclude that Venus must have had plate tectonics sometime after the planet formed, about 4.5 billion to 3.5 billion years ago. The paper suggests that this early tectonic movement ...

Which tectonic resurfacing regime dominated the observable geologic history of Venus?
Tectonic deformation at this time caused formation of strongly tectonized terrains such as tessera, and deformational belts. Exposures of these units comprise ~20% of the surface of Venus. The apparent beginning of the global tectonic regime is related to the formation of tessera, which is among the oldest units on Venus.
