Lava-Filled Blocks on Venus May Indicate Geological Activity

Paul Byrne, a planetary geologist at North Carolina State University who presented the new research, and his colleagues used radar images of Venus’s surface from the Magellan mission between 1990 and 1994 to view these structures from a global perspective. Doing so revealed a new pattern: these mountain ridges and grabens converge to isolate blocks of flat, low-lying plains of cooled lava along the planet’s poles, something never noticed before.
