Over 5,000 minerals are known to exist worldwide, of which more than 300 have been found in Iceland.
Minerals may be classified in a number of ways, for example by distinguishing between primary (rock-forming) minerals, i.e., minerals such as olivine and plagioclase (a kind of feldspar) that form as magma cools and rock comes into being, and secondary minerals such as zeolites, which are formed as already existing rocks undergo alteration and secondary precipitation in vesicles, cracks, and fissures.
Minerals are also classified on the basis of their crystal structure and chemical composition. The Natural Science Institute of Iceland makes use of the Nickel-Strunz Classification System (2001), where minerals are divided into 10 main classes on the basis of their composition, which are further organised into a number of divisions, subdivisions and groups on the basis of crystal structure and chemical composition. Some groups are organised into families. Certain minerals can be further divided into a number of varieties. Minerals found together in rock, formed under the same conditions, and in equilibrium with each other are known as mineral assemblages.

The crayon gives it authenticity, but I doubt that the orange man can read a map.

So are we Eastasia or Eurasia? Wait are WE Oceania? I kinda thought that would include the Pacific Island nations.

It's missing one of those sharpie additions, like the hurricane Dorian map one, to feel really authentic

Fake. He doesn't know Xi's name. Real one probably has a racist term for Chinese there. Might also call Putin Vlad.

He wants Iceland too. But why?

Iceland is also the only producer of bananas in the arctic.

That looks correct.
I still don't understand why super old fucks are interested in doing it.

They'll all be dead before they can do anything. Being so mad with power probably makes you think you're immortal.

Misspelled "announced" in the headline.
