Gibeon Meteorite
These come from one of the largest meteor-strewn fields found on earth. The Gibeon strewn field extends 40 miles wide and 250
miles long. Scientists believe that this meteorite entered the atmosphere at a 30-degree angle.
Most of the fragments of this meteor were found on the top of the ground. The natives of South Africa used this material for tools and weapons.
This iron meteorite has in it a unique crystallization known as the Widmanstatten crystal structure, a result of cooling in outer
space over billions of years. Assays of the recovered fragments yield 87% iron, 10% nickel, also small nodules of graphite and trolite and traversite. Scientists have also found rare minerals called
enstatite and tridymite. These minerals are only found in nuclear fusion. Some of the Gibeon fragments have also yielded silicate inclusions.
The Gibeon field was discovered by Europeans in 1836. Meteors are estimated to be between 5 and 6 billion years old, far older
than the earth which is estimated to be 4.6 billion years old.
