This listing is for the Gibeon Meteorite slice shown. This is a large complete slice, weighing exactly 754 grams (1.66lb) displaying the well-known Widmanstatten pattern formation. Fall date: Prehistoric times
The Gibeon meteorite entered our atmosphere at an incredible velocity of around 17 miles per second an estimated 30,000 years ago. It exploded high in the atmosphere showering fragments over a large region of what is present day Namibia, Africa. Prior to this, the meteorite had traveled through space for over four billion years before it was trapped by the Earth's gravitational field and pulled to earth as a brilliant fireball.
The Gibeon meteorite is classified as a group IVA fine octahedrite and is composed of approximately 91.8% Iron; 7.7% Nickel; 0.5% Cobalt; 0.04% Phosphorus; 2.4 ppm Iridium; 197 ppm Gallium; and 0.111 ppm Germanium. It was derived from the core of an extinct planet that was blown apart billions of years ago during the formation of our solar system by a catastrophic impact event.
