Mineral Wealth
After a formation discovered in Oman in the 1970s, New Caledonia has the planet's largest known outcrop of ultrabasic rock, derived not from the crust, but from an upthrust fold of the more deeply underlying mantle of the earth. These mineral-rich rocks are a source of nickel, chromium, iron, cobalt, manganese, silver, gold, lead and copper. The toxicity of the mineral-rich soil has helped preserve the endemic vegetation, which has long been adapted to it, from competition from would-be colonizers which find it unsuitable.

Famous quotes containing the word wealth:
“It is better to pay court to a queen ... than to worship, as we too often do, some unworthy person whose wealth is his sole passport into society. I believe that a habit of respect is good for the human race.”
—M. E. W. Sherwood (1826–1903)
