Alle Auktionen / Etnografica / Rare Gyarub Zangbo Pallasite Meteorite Olivine-Rich...
Beautiful polished slice of the Gyarub Zangbo pallasite meteorite, displaying a striking combination of metallic matrix and translucent olivine crystals. Gyarub Zangbo was discovered in October 2020 in Xizang, China, on the Qinghai–Tibet Plateau. It is officially classified by the Meteoritical Bulletin as an ungrouped pallasite. Pallasites are among the most visually spectacular meteorites, consisting primarily of olivine crystals embedded within an iron-nickel metallic matrix. In this specimen, the olivines range from golden-yellow and amber to darker greenish tones, creating particularly attractive contrasts when viewed under different lighting conditions. The slice has been covered with a transparent protective resin. This treatment helps isolate the metallic component from humidity and therefore reduces the risk of oxidation, while also stabilising the slice and allowing the translucent olivine crystals to be appreciated more clearly. Protective epoxy coatings are also used on documented Gyarub Zangbo slices for preservation. The photographs show the actual specimen offered. Meteorite: Gyarub Zangbo Classification: Pallasite, ungrouped Composition: Iron-nickel metal with olivine crystals Origin: Xizang, China – Qinghai-Tibet Plateau Find: October 2020 LPI Age: Primitive material dating from the formation of the Solar System, approximately 4.5 billion years ago Weight: 5 g Dimensions: approx. 2.5 × 1.5 cm Finish: Polished and protected with transparent resin A beautiful small-format specimen, ideal for a meteorite collection and especially attractive when illuminated.
