The surface of Venus is also volcanic in nature - as opposed to Earth's surface, which is a combination of volcanic, metamorphic, and sedimentary rock. That's because there is no liquid water on the surface of Venus. Likewise, there doesn't appear to be any plate tectonics on Venus - the heat generated by radioactive processes seems to continue to heat Venus' mantle until the crust disintegrates and the entire surface subducts and overturns, basically. Quite a different process than what occurs here on Earth.

BTW, the Venusian surface is ~300-600 million years old and there could be current volcanic activity.

For more information regarding the runaway greenhouse on Venus, read this article. It will get you started.
Well - at least we agree that a runaway greenhouse effect cannot cause vulcanism.

Where is the evidence that the surface of Venus is 300-600 million years old? This is the sort of thing W*gs does a lot. He makes a pronouncement -- and we are supposed to take it on faith.

No one has ever visited the surface of Venus. Nor do we have any rock samples. Therefor, there is not a scintilla of actual evidence for this claim. It is pure hokum -- something that Big Bang scientists are really good at.
