Venera 15 and 16 spacecraft radar images of 1.3-km resolution have confirmed that areas in the Venusian Ishtar Terra highlands appear to be crust which has been folded and faulted into mountains by horizontal compression. The new images also reveal crust that has been broken up by extension, and a depression designated Colette, on a plain on Ishtar Terra, is an obvious crater whose lava flows merge into and form that plain. The ability to distinguish between impact craters and volcanoes has allowed Soviet researchers to compare the number of obvious impact craters against the rate at which they would be expected to form. The resulting average age of the area observed thus far is about 1 billion years. This suggests that the surface has been reworked during the 4.5 billion year history of Venus.
