Dark colored igneous rocks are high in iron and other heavier elements: ma-fic, magnesium-iron. Light color igneous rocks are high in aluminum and potassium. .ou need to understand one of the fundamental differences between mafic and felsic rocks. Mafic rocks contain larger amounts of Mg and Fe than felsic rocks. The atomic weights of Mg and Fe are higher than Al, Si, and O, therefore they tend to be heavier. Very simple concept.
There are lots of different metals and lots of different stones. Aluminium, for example is less dense (lighter) than granite Iron is more dense than pumice (a volcanic rock that actually floats on water). Even rocks such as granite vary in density. To answer your specific example, as granite contains heavy metals it would normally be denser than iron. Obsidian is likely to be less dense than iron as it contains lighter elements. Generally the metals are heavier than stones.But not in all cases.
