Accompanied by a COA card and display case, this exceptional individual weighs 96.30 grams and features stunning olivine crystals. Originating from Algeria in 2022, this high-quality Pallasite meteorite is a captivating find from another world. Stay tuned for additional information once the research is concluded. Best of luck on your bids!" Pallasite meteorites are a rare type of stony-iron meteorite that is composed of olivine crystals embedded in an iron-nickel matrix. These meteorites are believed to have originated from the boundary regions between the core and mantle of a differentiated asteroid or planetesimal. Pallasites are important to science because they provide valuable insights into the processes that occurred in the early solar system and the formation of planetary bodies. The presence of olivine crystals in pallasites, for example, suggests that they formed at depths where temperatures were high enough for iron and nickel to be partially molten, while olivine remained solid. Studying pallasite meteorites can help scientists understand the thermal and chemical evolution of these parent bodies, as well as the conditions that existed in the early solar system. They can also provide information about the differentiation processes that occurred within these bodies and the potential for metallic core formation. Overall, pallasite meteorites are valuable specimens that can shed light on the history and formation of the solar system, as well as the processes that govern the formation and evolution of planetary bodies Northwest Africa 16774(NWA 16774) Algeria Purchased: 2024 Classification: Pallasite History: Found in the desert of MSila province, Algeria in 2022.
