Description: NWA 16782 is classified as a Ureilite, Primitive achondrite. It is a 12.347 gram slice with a fine polish on one side, showcasing its unique characteristics. It comes with a COA card and display case. This meteorite has been classified as a Ureilite, which is a rare type of stony meteorite that contains olivine and pyroxene minerals. Ureilites are thought to originate from the mantle of a differentiated asteroid that experienced high temperatures and underwent a process of partial melting and subsequent crystallization. Ureilites are particularly interesting to scientists because they provide insights into the early stages of planetary formation and differentiation. The presence of carbon in Ureilites has led researchers to believe that these meteorites may contain traces of organic materials, adding to their scientific importance. Further analysis of NWA 16782 and other Ureilites could potentially reveal important information about the conditions in the early solar system and shed light on the processes that shaped the formation of planets and asteroids. Research on meteorites like NWA 16782 continues to expand our understanding of the universe and our place within it. Ureilites are a type of achondritic stony meteorite that is believed to have originated from the mantle of a differentiated asteroid. They are thought to have formed around 4.5 billion years ago during the early stages of the solar system's formation. The exact process of their formation is still not fully understood, but it is believed that they experienced some level of differentiation and melting within their parent asteroid before being ejected into space and eventually landing on Earth. Some ureilites contain small diamonds that are believed to have formed under high pressure conditions within the parent asteroid. It is thought that these diamonds were created through shock metamorphism, a process in which high pressures and temperatures caused by impacts or collisions converted graphite (carbon) in the asteroid into diamond. These diamonds are typically microdiamonds, which are very small and can only be seen under a microscope. The presence of diamonds in ureilites has provided valuable insights into the pressure and temperature conditions within the early solar system and the processes that occurred within differentiated asteroids.
