This means that in this ore deposit, the copper is concentrated 857 times above the average crustal abundance. Ore deposits consist of rocks called ores. An ore is a mixture of valuable ore minerals and lowvalue gangueminerals. Most ore minerals are compounds of either oxygen ( metal oxides) or sulfur (metal sulphides).

Abstract. The evaluation of the abundances of chemical elements in the Earth's crust is a pivotal geochemical problem. Its first solutions in the early 20th century formed the empirical groundwork for geochemistry and justified concepts about the unity of the material of the Universe, the genesis of the chemical elements, and the geochemical differentiation of the Earth.
