Venus: Further Evidence of Impact Cratering and Tectonic Activity from Radar Observations

Venus: Further Evidence of Impact Cratering and Tectonic Activity from Radar Observations

Earth-based radar images at a resolution of 10 kilometers show a diverse surface terrain on Venus, probably produced by both impact events and tectonic activity. Only a small number of craters of apparent impact origin are seen. Largescale features show lineaments and parallel ridges suggesting tect...

Zusammenfassung:Earth-based radar images at a resolution of 10 kilometers show a diverse surface terrain on Venus, probably produced by both impact events and tectonic activity. Only a small number of craters of apparent impact origin are seen. Largescale features show lineaments and parallel ridges suggesting tectonic origins.
