Description: Hi my name is Luisa Stream, im part of Streaming meteorites. Im excited to be here, every meteorite I sell comes with a COA card and display✨ meteorite: NWA 16875 Weight 1.763 Grams. Beautiful This rare meteorite is a must-have for any collector of meteorites. The NWA 16875 Provisional Winonaite endcut weighs 8.892 grams and is a new primitive achondrite. Its unique composition and history make it a valuable addition to any collection. The meteorite is believed to have originated from the early solar system, and its discovery provides insights into the formation and evolution of our universe. Add this piece to your collection and marvel at the wonder of our cosmos. This meteorite is a new find from Algeria 2023, and is approved as a rare primitive achondrite known as a Winonaite! This meteorite was just submitted to the nom com and will soon be published. It will come with a COA card and display case. primitive achondrite: A meteorite that has lost its chondritic texture due to heating and partial melting, but still has nearly chondritic composition. winonaite: Winonaites, named after the Winona, Arizona, find of 1928, are equigranular rocks, some of which may contain relict chondrules, that have mineralogy and composition that are similar to chondrites.The mineral assemblage is more reduced than that of H chondrites. Winonaites are related to the silicate inclusions found in IAB complex irons. Winonaite meteorites are a rare type of chondritic meteorite, classified primarily by their unique mineralogy and formation process. Here are the key details: Formation: 1. **Parent Body**: Winonaite meteorites are believed to originate from a differentiated asteroid that has undergone significant thermal processing. This means the asteroid had enough internal heat to separate into different layers, leading to the formation of a crust, mantle, and core. 2. **Conditions**: The minerals found in winonaite meteorites suggest they formed under high-temperature conditions, likely in the early solar system. They are thought to have resulted from partial melting, which led to the crystallization of specific minerals. 3. **Chemistry**: The mineral assemblage commonly includes olivine, orthopyroxene, and metal grains, indicating the influence of both silicate and metallic processes during formation. Importance: 1. **Understanding Solar System History**: Winonaite meteorites provide valuable insights into the conditions of the early solar system. Studying them helps researchers understand the processes of formation and differentiation of planetary bodies. 2. **Rare Resource**: Winonaites constitute a small fraction of meteorite falls, making them invaluable for scientific research. Their unique characteristics can help scientists draw conclusions about the geology of other celestial bodies. 3. **Planetary Science**: These meteorites serve as analogs for understanding other differentiated bodies in our solar system, enhancing knowledge about processes like volcanism and tectonism on asteroids and possibly even planets. Age: 1. **Radiometric Dating**: Winonaite meteorites are typically very old, with ages determined using radiometric dating techniques. Many have ages of around 4.5 billion years, which is roughly the age of the solar system itself. 2. **Cosmochemical Evidence**: The isotopic compositions of elements in winonaite meteorites show that they formed after the presolar stage, during the early accretion and differentiation phases of our solar system. By examining these meteorites, scientists are able to piece together the environmental conditions and events that led to the formation of the terrestrial planets, enhancing our understanding of our own planet's history and composition.
