Get PricePairs of elements that commonly substitute for one another in silicates are: Si and Al; Mg and Fe (and also Al) Na and K; Na and Ca. Silicate Minerals Oxygen and silicon are the most abundant elements in the Earth's crust, and the Si-O bond is among the strongest in minerals. Consequently, most of the crust is composed of silicate minerals.
