Thick lithosphere casts doubt on plate tectonics in Venus’s geologically recent past – Phys.org

At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers has used that ancient impact scar to explore the possibility that Venus once had Earth-like plate tectonics.
For a study published in Nature Astronomy, the researchers used computer models to recreate the impact that carved out Mead crater, Venus’s largest impact basin. Mead is surrounded by two clifflike…
