Kelimpahan unsur

Tabel ini menunjukkan kelimpahan unsur-unsur di kerak Bumi. Angka menunjukkan persentase atau bagian per juta (ppm) dalam massa; 10.000 ppm = 1%.

Perlu diperhatikan bahwa angka merupakan perkiraan, dan mereka akan bervariasi tergantung pada sumber dan metode estimasi. Secara garis besar, data dapat dipercaya.
