Geological information

Abundances

In this table values are given in units of ppb (parts per billion; 1 billion = 10⁹), both in terms of weight and in terms of numbers of atoms. Values for abundances are difficult to determine with much certainty, so all values should be treated with some caution, especially so for the less common elements. Local concentrations of any element can vary from those given here by orders of magnitude.

	Meteorite (carbonaceous)	6700	1600
	Crustal rocks	130000	30000

Notes

Zirconium is never found as the free metal. The main ore is Zircon (ZrSiO₄) and this is found in deposits in Australia, Brazil, India, Malysis, Russia, and the USA. All these minerals contain a little hafnium as well and the separation of the two is difficult.

Zirconium has been found in the spectra of S-type stars and has been identified in the sun and meteorites. Lunar rock samples show a surprisingly high zirconium oxide content as compared to rocks from earth.
