Ultra high precision analyses of some of the oldest rock samples on Earth by researchers at the University of Bristol provides clear evidence that the planet's accessible reserves of precious metals are the result of a bombardment of meteorites more than 200 million years after Earth was formed.
During the formation of Earth, molten iron sank to its centre to make the core. This took with it the vast majority of the planet's precious metals -- such as gold and platinum. In fact, there are enough precious metals in the core to cover the entire surface of Earth with a four-metre thick layer.
The removal of gold to the core should leave the outer portion of Earth bereft of bling. However, precious metals are tens to thousands of times more abundant in Earth's silicate mantle than anticipated. It has previously been argued that this serendipitous over-abundance results from a cataclysmic meteorite shower that hit Earth after the core formed. The full load of meteorite gold was thus added to the mantle alone and not lost to the deep interior.
To test this theory, Dr Matthias Willbold and Professor Tim Elliott of the Bristol Isotope Group in the School of Earth Sciences analysed rocks from Greenland that are nearly four billion years old, collected by Professor Stephen Moorbath of the University of Oxford. These ancient rocks provide a unique window into the composition of our planet shortly after the formation of the core but before the proposed meteorite bombardment.

A girl can dream, can’t she? :)
Who the h3ll is THAT? LOL!
Liberals have taken history and rewritten it. They have taken science and perverted it. But they love to bestow the title “intellectual” and “cultured” on themselves.
YOU don’t plant anything - the fruit trees and vegetable garden are already there for you - you just pick them off - like Adam/Eve did. The door is one giant pearl. Do you prefer asphalt to gold?
But you don’t have to go if you think ANYTHING God has is horrible. Are you enjoying this earth/USA - if evil was taken out of it?
LOL...gotta *catch* the right guy....or, so I’m told.:)
You choose bible verses at random, out of context, that fail to support your position.
Believe what you choose; “work out your own salvation with fear and trembling”. I read the Bible too, and I see a different side of the LORD than your head-in-the-sand dogma dictates.

I’m working on reelin’ one in these days. He’s the size of Brett Favre, so it’s taking me a while to land him, LOL!
I’m losin’ my touch - I’m usually at the altar again by now, LOL!
It will undoubtedly be more wonderful than we can imagine.
Let me just remind you that before the fall, God assigned a purpose for men:
15 The LORD God took the man and put him in the Garden of Eden to work it and take care of it.
Genesis 2:15
Peace.
I don't allow digging or metal detecting in my back-yard.
Whew! I’m sure glad you abbreviated that presentation. My head was starting to hurt following all the large number calculations (I don’t like adding and subtracting co’s).

Oh man! And here I was hopin’ you were gonna get all impressed with mah technical know-how! 8<)
(If I did all those equations again for the next 200 common isotopes, would it be any more clear??? We could throw in radioactive decay times and probabilities for all them there nuclear reactions and times for the supernova generations to burn up stars .....Get into Einstein's relativistic accelerations as the particles speed away from the supernova ...)
I struggled for a while, but you came up with a good one.
Don’t you watch TV?
GOLDLINE!

I wonder why...LOL! :)
