The oldest rocks in this false-color image of Leda Planitia (plains) of Venus are the bright, highly-fractured highlands in the upper left. The darker plains that surround the highlands formed when volcanic lava filled the low-lying areas. Plains like this cover as much as 80% of the surface of Venus. The most recent lava flows are the bright areas in the upper right.
The circular structure in the lower left is probably an impact crater. Venus is struck by meteors at about the same rate as Earth.
