Is it true?

[pioneer0333]

It is it true that some meteorites can contain gold or silver or even diamonds.<br /><br /> If so, where was this meteorite found? <div class="Discussion_UserSignature"> </div>

Meteorites are divided into three main types: Stone, iron and stony-iron; reflecting their composition. 96% of meteorites are stony, made up of the same silicate minerals (olivine, pyroxene, plagioclase) as many terrestrial rocks. <br /><br />The stony meteorites are sub-divided into chondrites and achondrites. <br /><br />Chondrites contain tiny grains of dust that came from stars other than the Sun. These grains are diamonds (only 3 nm across) and silicon carbide (or carborundum). <br /><br />Meteorites can also contain trace amounts of precious metals like gold, silver, platinum, and the other platinum group metals: palladium, irridium, rhodium, osmium, and ruthenium.<br />

To give you a short answer, it is Yes. Meteorites also contain zircon, feldspar and several other elements. <br /><br />For more information on meteorites visit the Wikipedia site.<br /><br />http://en.wikipedia.org/wiki/Meteorite<br /><br />Catch A Falling Star!

I came across a book stating meteorites account for about 5,000 tons of metals added to earth everyday. <br /><br /><font color="yellow">War is old men talking and young men dying. <br /></font><br /><br />Troy? <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p>pain is inevitable</p><p>suffering is optional </p> </div>

I saw a show last week that says we got all of our ocean water from millions of years of comet deposits.

 

[scull]

Did they say if the chemical composition of water in comets the same as in our oceans?<br /><br /><br /><br /><br />s--

 

[eric2006]

The gradual change in salinity and the minerals dissolved over the years would make it impossible.<br /><br />They are talking early days of the solar system. First millions.<br /><br />It doesn't sound logical to me. That would have to be millions of comet collisions.

 

[scull]

I agree. All the comets from the heavy bombardment period could not account for all the water. <br /><br />So... ummm.... where do you think it came from?<br /><br /><br /><br />--

 

[eric2006]

I think it came from a consumer driven galaxy. There was a star system named evian centauri. They kept all of their supplies here to drive up the market value and then they where killed by a gamma ray blast. The galactic government was worried and tried to form a branch called OSHA. The Martian's thought they said ocean and fearing they would steal all their water they took it and that is why there is none on Mars. <img src="/images/icons/crazy.gif" />

LOL<br /><br />But if I remember the history of evian centauri correctly, the centaurians had a more sinister objective. They wanted earth for themselves. The water they stored here was contaminated; it killed off the dinosaurs. <br /><br />This is where the saying "Don't drink the water" comes from.<br /><br /><br />s--

They spoiled the water. They actually told the dinosaurs not to drink it. But they were stupid and lazy and did not heed the warning. T-Rex was the first to drink and his offspring had genetic defects. One was the shortening of the arms. The other dinosaurs laughed at him and wouldn't let him join in games. But they soon got thirsty as well. Some even bathed in it. This caused the water to become brown and acidic. That is where we got the saying, "Don't eat the brown acid".<br /><br />Some say it was the break down of the family value's that killed them off. But I think it was the water.

 

[scull]

LOL....<br /><br />No, no, no, the dinosaurs were the good guys. They actually raised an army against the alien-race of centaurians. But the water was bad: they puked & you- know-what to death.<br /><br />Don't eat the brown acid??? That must be an American saying, because I've never heard it here in the North Pole.<br /><br /><br />--<br /><br /><br />

 

[eric2006]

The brown acid resurfaced circa late '60's @ a place called Woodstock. Ignoring the testimony of the dinosaurs, forever locked in their rocky tombs, they ate of the acid. They became ill. Some even swear they saw the centaurians running around. <br /><br />BTW...Your profile says you're from Mercury. They have poles as well? Is there a Santa there also?

 

[scull]

Mercury is the SECOND planet.<br /><br />I'm from the planet Vulcan. Polar expeditions are piling up at our poles because of the singularities. We don't have a Santa; we have a Satan.<br /><br /><br />s--

 

[eric2006]

I'm sorry to hear that. Does he come down the chimney and do the kids leave him cookies?

 

[scull]

Satan comes down the chimney at midnight with a pitchfork and eats the kids like cookies.<br /><br /><br /><br />s--

Where would one get comet atoms to test isotopes against Earth water? I read the article fast I might have missed it. I read the numbers but I didn't see how got their data.<br /><br />Could the primordial water have filled into the area knocked out by the moon? Also, why wouldn't gravity bring the water back to Earth?

 

[scull]

I'm sure Deep Impact got some cometary material from its collision with Tempel 1.<br /><br />As for the other questions...... I'm clueless.<br /><br /><br /><br />scull667--
