Geochemistry of Uranium in Apatite and Phosphorite
Apatite, by effectively removing the small amounts of U(IV) produced in sea water by reduction of (UOa)*s, causes more U(IV) to be produced for its own uptake. As the marine apatite is far from saturated with respect to uranium, it thus interferes with the attainment of equilibrium while fixing an unusual quantity of U(IV).

Mohs Hardness Scale - Geology Page
The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching. It is a very simple but inexact comparative test. Perhaps its simplicity has enabled it to become the most widely used hardness test. Since the Mohs Scale was developed in 1812, many different hardness tests have been invented.
