AI-assisted summary
Description from the seller
The Lancé meteorite, which fell on July 23, 1872, in Loir-et-Cher, France, is a major scientific rarity.
It is a carbonaceous chondrite of type CO, one of the rarest and most primitive types known, valuable for understanding the formation of the solar system.
Characteristics and rarity.
• Observed fall: Six stones totaling 52 kg were recovered, including a large block of 47 kg.
• Chemical type CO: It contains small chondrules and calcium- and aluminum-rich inclusions.
• Global significance: It is the second heaviest CO-type fall ever recorded on Earth.
Historical and scientific value.
• Primitive origin: These primordial fragments have not changed since the birth of the solar system, over 4.5 billion years ago.
• Distribution: The largest piece is preserved at the Natural History Museum of Vienna, Austria. It is a French meteorite and very little material circulates on the market, making it quite difficult to acquire!
Precise chemical composition (Type CO3.5).
The Lancé meteorite belongs to the very restricted group of carbonaceous CO chondrites (Ornans-like). The number 3.5 indicates that it has remained very primitive and has undergone almost no alteration by heat or water since its formation.
• Carbonaceous matrix: It contains between 0.2% and 1% total carbon. This is complex extraterrestrial organic matter in the form of insoluble macromolecules.
• Dominant silicates: Its rocky structure is mainly olivine (about 40%) and pyroxene (about 30%).
• Tiny chondrules: It is studded with minute molten silicate spheres (chondrules) of less than 1 mm in diameter.
• Refractory inclusions (CAIs): It contains whitish inclusions ultra-rich in calcium and aluminum. These are among the very first solids to have condensed in the primitive solar nebula.
• Low water and metal content: Unlike other carbonaceous chondrites, it contains less than 1% water and very little iron in metallic form.
Beautiful specimen of 0.100 g (5x5x4 mm) under a solid glass display case with a Certificate of Authenticity!
Buy with confidence, I’ve been collecting meteorites for over 35 years and I am member #7669 of the IMCA (International Meteorite Collector Association). Take advantage of the opportunity as I am gradually reorganizing my collection, which still currently comprises several hundred specimens...
