What is the most common type of rock on Venus?

The surface of Venus, our nearest neighbor planet, is covered with rocks of varying types. However, basalt is the most common type of rock on Venus. Basalt originates from lava flows and is rich in minerals like pyroxene and olivine. Basalt is found in large quantities on Venus and covers about 75% of its surface.

The presence of basalt on Venus suggests that significant volcanic activity has taken place in the planet's history. The frequent volcanic eruptions could have been responsible for the thick atmosphere on Venus, which traps heat and causes a runaway greenhouse effect, making Venus the hottest planet in the Solar System.
