On the geologic map shown here (actually more a tectonic map), yellow areas are 1 km and more above the mean elevation of Venus. These areas are generally large volcanic centers. There are two large "continents" on Venus that contain large areas of tectonically uplifted and deformed crust. Blue areas are below the mean radius of Venus and comprise most of the Planitia areas on Venus. These areas are mostly lava plains with no to moderate amounts of deformation.
Structual features are shown as follows:
The south polar region of Venus is one of the most bland areas of the planet, with few tectonic features of note.
