What kind of stuff makes up the North Pole?

Gen.2:10-14
10. Now a river went out of Eden to water the garden, and from there it parted and became four riverheads.
11 The name of the first is Pishon; it is the one which skirts the whole land of Havilah, where there is gold.
12 And the gold of that land is good. Bdellium and the onyx stone are there.
13 The name of the second river is Gihon; it is the one which goes around the whole land of Cush.
14 The name of the third river is Hiddekel;fn it is the one which goes toward the east of Assyria. The fourth river is the Euphrates.

Gen 3:22-24
22. Then the LORD God said, “Behold, the man has become like one of Us, to know good and evil. And now, lest he put out his hand and take also of the tree of life, and eat, and live forever”—
23 therefore the LORD God sent him out of the garden of Eden to till the ground from which he was taken.
24 So He drove out the man; and He placed cherubim at the east of the garden of Eden, and a flaming sword which turned every way, to guard the way to the tree of life.
