Description: Subject: Premium Flight-Oriented Meteorite for Sale I am pleased to present for sale a remarkable flight-oriented meteorite that embodies both beauty and scientific interest. This stunning specimen, characterized by its shield shape, weighs an impressive 231.00 grams. It features a frothy fusion crust and a pronounced rollover lip, which are indicative of its unique characteristics. **About Flight-Oriented Meteorites:** Flight-oriented meteorites are formed during their passage through the Earth's atmosphere. This process can result in distinctive aerodynamic shapes that provide insights into their journey. The rollover lip observed in this particular meteorite indicates that it experienced significant heating and pressure during its descent, contributing to its unique formation. This meteorite was recently discovered in Algeria in 2023, and I acquired it from a reputable dealer in the region. It comes with a Certificate of Authenticity (COA) to verify its provenance and quality. Thank you for considering this exceptional specimen for your collection. Should you have any questions or need further information, please feel free to reach out. Best regards, The meteorite exchange says: Oriented meteorites have frozen in their shape and surface the record of their fiery passage through the Earths atmosphere. All meteorite arrive on the surface of our world by the same experience, but only the rare few that are stable during flight will show the marks of ablation and accumulation. These are the oriented meteorites. Some of these marks are radial flow lines, splattered material clinging to the sides behind the forward surface, and lips and ridges of melted material that has flowed as liquid back from the front. Any type of meteorite can be an oriented one. The material is not what is important. It is the fact that only one surface remains the forward surface during the ablation part of entry flight. There are some very famous oriented stones. Martin Horejsi shared in this publication last month the Eagles Nest oriented meteorite which is a stone type. But, with large numbers of small irons currently available from falls such as Taza, and Sikhote Alin, offer us a portion of their numbers that are oriented. I have spent a good deal of my time at gem shows hunting through trays of these for oriented specimens. Ordinary chondrites are a type of stony meteorite that makes up about 87% of all known meteorites. They are primarily composed of silicate minerals and exhibit a chondritic texture characterized by the presence of small spherical particles called chondrules. Here are some key features and information about ordinary chondrites: Composition - **Mineral Content**: Ordinary chondrites generally contain olivine, pyroxene, and feldspar. They also include metallic iron-nickel and sulfide minerals. - **Chondrules**: These are spherical grains that formed early in the solar system from molten or partially molten droplets. Classification Ordinary chondrites are categorized into three main groups based on their composition: 1. **H Chondrites**: High in metallic Fe and Ni and relatively high in iron. 2. **L Chondrites**: Lower in metallic iron and nickel compared to H chondrites and contain more silicate minerals. 3. **LL Chondrites**: Low in iron and metal contents, they have a higher concentration of other elements like sulfur. Origin - **Formation**: Ordinary chondrites are believed to be remnants of the early solar system, formed about 4.56 billion years ago. They originate from the parent bodies of asteroids, which have undergone differentiation and thermal processes. Significance - **Planetary Formation**: Studying ordinary chondrites provides insight into the processes of planetary formation, differentiation, and conditions in the early solar system. - **Cosmic Ray Exposure**: They help researchers understand cosmic ray exposure ages, as these meteorites have been exposed to radiation for extended periods in space. Examples Some well-known examples of ordinary chondrites include: - **Allende**: A famous carbonaceous chondrite that fell in Mexico in 1969. - **Millbillillie**: Discovered in Australia and noted for its diverse mineralogical features. Importance in Research - Ordinary chondrites are valuable for both planetary science and astrobiology. They serve as analogs for understanding the early Earth and the conditions that might have led to the origin of life. Conclusion Ordinary chondrites are crucial to our understanding of meteorites and the early solar system. Their diverse chemical and mineralogical compositions provide essential clues about the formation and evolution of planetary bodies.
