Aug 6, 2024 · 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 geodynamics in Venus ...
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.
Venus' 'continents' suggest surprising link to ... "We did not expect Venus, with its scorching 460°C surface temperature ... Venus raised by craton-like formation mechanisms. Nature Geoscience
Oct 26, 2023 · Venus, on the other hand, Earth’s nearest neighbor and sister planet, went in the opposite direction and today has surface temperatures hot enough to melt lead. One explanation is that the planet has always been thought to have what’s known as a “stagnant lid,” meaning its surface has only a single plate with minimal amounts of give, movement and gasses being released into the atmosphere.

Jan 1, 2014 · Is it Earth-like, with a young surface, plate tectonics, and tracks of hot-spot volcanoes, or like the smaller planets, with a heavily cratered surface? When imagination outstripped data, Venus was thought to have an Earth-like hot swampy surface, but we now know that its CO 2 atmosphere, sulfuric acid clouds, surface temperatures hot enough to melt lead, and very slow and retrograde rotation ...
