Olivine... if you can find on the internet the "Bowens Reaction Series" paper, it will tell you that Olivine is the first to crystallize
olivine and plagioclase [calcium feldspar]

Amethyst
Cavemen
There are about 560 minerals found in Ontario, only 34 were discovered there. :)
There are thousands of minerals that have been found in the world, and many more discovered every year. The number of minerals that are considered common depends on where a person lives. Gold, aluminum, silver, and copper are common mineral examples.
Rhenium was discovered in Germany by Walter Noddack, Ida Tacke and Otto Berg.
They are inorganic salts, they are man made- prussian blue was discovered over 200 years ago- the salts do not occur in nature- so are not normally considered to be minerals.

Miners were the first people to discover minerals in Texas.

Hafnium was discovered by Dirk Coster and Von Hevesy in zirconium minerals after X-ray spectrometric analysis.
Over 200 million and more are stilling being discovered
Uranium (as an oxide) was discovered in 1789 by Martin Heinrich Klaproth in minerals from Johanngeorgenstadt (Germany) and Jachimov (now in Czech Republic).

Norman L. Bowen discovered the crystallization sequence that produced most of the rock-producing minerals. Known as the Bowen Reaction Series, he was the first to reproduce plagioclase.
- They discovered that radiations are emitted from the uranium atom (and not from the molecule containing uranium) and are dependent on the quantity of uranium. - They discovered polonium and radium in uranium minerals.
