No the most abundant minerals in the earths crust are Silicates due to the over all abundance of the elements Oxygen and Silicon. A good example of a Silicate is Quartz. The overall composition of the Earth is mostly iron (Fe), oxygen (O), silicon (Si), magnesium (Mg), nickel (Ni) and sulfur (S). Most of the mass of the Earth occurs within the mantle which is largely ferromagnesium silicate minerals olivine and pyroxenes.
