This meteorite comes with a COA card and display case. Thanks for your interest and take care. Geology com says: Where Do Iron Meteorites Come From? In the classic 1959 adventure film, Journey to the Center of the Earth, based on Jules Verne's wonderful book Voyage au Centre de la Trre, a team of explorers led by a very proper and resourceful James Mason, encounter giant reptiles, vast underground caverns, oceans and the remains of lost civilizations in a subterranean world hidden far beneath our planet's crust. If we actually could make such a journey to the Earth's center, our real-life adventure would be a rather short one, as the core of our planet is a sphere of molten iron with a temperature in excess of 4,000C. The world imagined by Verne makes for a more exciting film, but without molten planetary cores we would not have iron meteorites. Astronomers believe that in the early days of our Solar System, more than four billion years ago, all of the inner planets had molten cores. As our Earth is the largest of the Terrestrial planets (those composed largely of silicate rocks, as opposed to gaseous planets) it likely has a higher internal temperature than our smaller neighbors: Mars and Mercury. We also know that at least some asteroids in the Asteroid Belt between Mars and Jupiter once had molten cores, and these bodies were the parents of iron meteorites. Their cores are believed to have been heated by radioactive elements and to have reached temperatures around 1,000C. The eminent meteoriticist Dr. Rhian Jones of the Institute of Meteoritics in Albuquerque succinctly explains the result: "In a melted asteroid, melted rocky material and melted metal do not mix. The two liquids are like oil and water and stay separate. Metal is much denser than the rocky liquid, so metal sinks to the center of the asteroid and forms a core." This liquid metal consisted largely of iron and nickel, which cooled very slowly over a period of millions of years, resulting in the formation of a crystalline alloy structure visible as the Widmansttten Pattern [see below] in iron, and some stony-iron, meteorites that have been sectioned and etched. A catastrophic event that led to the destruction of some of these asteroids - such as a collision with another substantial body - scattered iron-nickel fragments into space. Occasionally these fragments encounter our planet and hurtle, melting, through our atmosphere. Those that survive and land upon Earth's surface are iron meteorites.
