She has taught science courses at the high school, college, and graduate levels. our editorial process Facebook Facebook Twitter Twitter Anne Marie Helmenstine, Ph.D. Updated February 18, 2020 This is a table that shows the elemental chemical composition of the Earth's crust. Keep in mind, these numbers are estimates. They will vary depending on the way they were calculated and the source. 98.4% of the Earth's crust consists of oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium. All other elements account for approximately 1.6% of the volume of the Earth's crust. Major Elements in the Earth's Crust Element Percent by Volume oxygen 46.60% silicon 27.72% aluminum 8.13% iron 5.00% calcium 3.63% sodium 2.83% potassium 2.59% magnesium 2.09% titanium 0.44% hydrogen 0.14% phosphorus 0.12% manganese 0.10% fluorine 0.08% barium 340 ppm carbon 0.03% strontium 370 ppm sulfur 0.05% zirconium 190 ppm tungsten 160 ppm vanadium 0.01% chlorine 0.05% rubidium 0.03% chromium 0.01% copper 0.01% nitrogen 0.005% nickel trace zinc trace Mineral Composition The crust is chemically similar to andesite. The most abundant minerals in the continental crust are feldspar (41%), quartz (12%), and pyroxene (11%) Keep in mind, the elemental composition of the Earth's crust is not the same as the composition of the Earth. The mantle and core account for significantly more mass than the crust. The mantle is about 44.8% oxygen, 21.5% silicon, and 22.8% magnesium, with iron, aluminum, calcium, sodium, and potassium. The Earth's core is believed to consist primarily of a nickel-iron alloy. Sources Haynes, William M. (2016). "Abundance of Elements in the Earth's Crust and in the Sea."
