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.
Only one Igneous rock is shiny that's obsidian and the reason its shiny is because since its extrusive rock it cools faster since Earths surface is cooler than the areas aroun â¦ d the core so it cools fast so not enough crystals can form so it looks like black glass.nly one Igneous rock is shiny that's obsidian and the reason its shiny is because since its extrusive rock it cools faster since Earths surface is cooler than the areas aroun â¦ d the core so it cools fast so not enough crystals can form so it looks like black glass.
