Deep sea mining is the extraction of minerals from the seabed of the deep sea. The main ores of commercial interest are polymetallic nodules, which are found at depths of 4–6 km (2.5–3.7 mi) primarily on the abyssal plain. The Clarion-Clipperton Zone (CCZ) alone contains over 21 billion metric tons of these nodules, with minerals such as ...
It formed out of basaltic magma by fractional crystallization [50] and had a temperature of about 1,000 °C (1,830 °F). [12] Its eruption may have been triggered either by the entry of new magma into the magma chamber or the effects of gas bubble buoyancy. [51]
Complex phenocryst assemblages found in a sample indicate that the magma formation is a complex process. [34] Taftan rocks overall are potassium-rich calc-alkaline, [47] [33] of sub–alkaline affinity. [45] The magma that formed these rocks was influenced by crystal fractionation and mixing processes.

[4] [5] The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 160 kilometres (100 mi) wide in places and over 61 metres (200 ft) deep.

This is sometimes referred to as a unit of standard atmospheres (atm). Total atmospheric mass is 5.1480×10 18 kg (1.135×10 19 lb), [ 42 ] about 2.5% less than would be inferred from the average sea level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain.
