Most of them can not be poured during the event from the magma is not the consistency of water, it is viscous. Moreover, the surface regions where the temperature is much lower, will not allow these minerals and elements to flow, because the atmosphere is as thick as it was today 'hui.

Note that the bombing there in the late 3.8-4.1 million years ago? Earth has cooled enough (and only after 300 million years after the disaster of the side rail) does not allow more than sinks and a solid crust that are broken from asteroids. Most asteroids in this case, the registration over 10 miles in diameter and can have large quantities of gypsum in heavier elements in the crust. Earth can withstand such collisions still persecuted in the future. I also remember another story insignificant, but interesting to see how the elements were mainly iron deposited in the earth's crust. There are about 30,000 years ago, the solar system came into the borders of the shell of a supernova shell, probably a member of the Centaurus-Lupus-SCOROB1 Pio. It was found when a large number of mammoth tusks were found shot deeply rooted micro-iron. Imagine something like in this case every few million years, and you have a large amount of heavy elements around.

Clear Skies!

Yes, I mean iron asteroid Subury, Canada and Minnesota and other places where they are involved in iron meteorites or asteroids. The stone that the Muslims is to five times a day Mecca, a large iron-nickel meteorites aligned. Traces of magnetic fields on Mars are probably buried asteroids.

The Earth formed from small planets and asteroids, many, no doubt, as Eros. The heavier elements tend to a lower level before the damn solidified sink, but certainly not all.
