The reported gold contents of meteorites range from 0.0003 to 8.74 parts per million. Gold is siderophilic, and the greatest amounts in meteorites are in the iron phases. Estimates of the gold content of the earth’s crust are in the range ~f 0.001 to 0.006 parts per million.

How much are gold meteorites worth
According to Bill Cook of NASA’s Meteor Office at the Space Flight Center. Marshall, these parts can cost upwards of $9,000. Based on today’s market prices, this is about 3.6 times the value of the precious metal silver (about $1,660 per troy ounce – 31.1 grams).
Did gold come from meteor shower
Based on analysis of some of the world’s oldest gravel materials, scientists have obtained the first direct evidence that a meteor cataclysm changed the chemistry of the early Earth. The coming confirms the theory that some meteors delivered gold, other metals and rare metals to the young Earth.
Are there precious metals in meteors
Most “iron” meteorites are iron-nickel alloys with almost a small amount of inclusions dispersed by sulfurous substances. The 5 alloys contain 17% nickel with traces of cobalt, chromium, gold, platinum, iridium, tungsten and other elements dissolved in this molten iron, and through information technology have penetrated the three quantities of the human body.
Are meteorites rarer than gold
Carbon dating suggests that each meteorite was on Earth between 250 and 1,000 years ago, and in fact there were several meteorites between the 18 sightings that could correspond to its own arrival on our planet. The analysis states that the Maryborough meteorite is undoubtedly much rarer than gold.

Do meteors contain gold
The gold content of meteorites has been reported to range from 0.0003 to 8.74 parts per million. Gold is almost certainly siderophile, and is found in the greatest amount in iron meteorites. Estimates of gold content in the earth’s crust often range from ~ f 0.001 to 0.006, per million.
Does gold come from meteors
The famous gold content of meteorites is from 0.0003 to 8.74 parts in length by several. Gold is a siderophile, in meteorites it is more abundant in the main phases of iron. The gold content in the earth’s crust is estimated to be in the range of ~f 0.001, possibly as high as 0.006 parts per million.
