The Sericho pallasite is a remarkable meteorite discovered around 2016 near the village of Habaswein in Wajir County, Kenya. Classified as a pallasite—a rare type of stony-iron meteorite—it consists of a nickel-iron metal matrix richly embedded with olivine crystals, often of gem-quality peridot. The Sericho meteorite is notable for its large mass and the abundance of recovered specimens, with individual pieces weighing up to several hundred kilograms. Its discovery has provided scientists with valuable insights into the formation and differentiation of early planetary bodies, as pallasites are believed to originate from the core-mantle boundary of disrupted asteroids. The Sericho pallasite not only holds scientific significance but also captivates collectors and enthusiasts with its striking, translucent crystals set in shimmering metal
When examining a pallasite meteorite under a light microscope, several distinctive features can be observed:
- Olivine Crystals: The most prominent component is the large olivine grains. Under transmitted light, olivine appears transparent or translucent with high relief.
- Metallic Matrix: The nickel-iron metal in pallasites is opaque under transmitted light microscopy, appearing as dark or black areas. However, using reflected light microscopy, the metallic phases become visible, revealing a shiny, metallic luster. This allows for the observation of the texture and distribution of the metal relative to the olivine crystals.
