It might be because we have believed that the lightning model predicts cooling rates of chondrules that are too fast to reproduce their textures with the …
Upper limits of water contents in olivine and orthopyroxene of ...
WebPyroxene seems to be somewhat variable regardless of shock pressure, even within the same sample. Shock may have an effect on the diffusion rate of pyroxene, but given the … Webing melt inclusions are observed. A few thin shock melt veins (<20 µm in width) are observed in our sample. The shock melt veins are composed mainly of tiny Al-rich pyroxene grains (<1 µm in size). Aggregates of stishovite and silica glass (up to 13 µm in size) and pyroxene fragments with a smooth outline are also observed in the shock melt ... cole harris realtor
Shock-produced akimotoite in the Suizhou L6 chondrite
WebThe effects of shock on pyroxene spectra are most prevalent in the VNIR, causing an overall flattening of spectral features. Decreases in band depth due to shock are also observed in … Web(including olivine, pyroxene, plagioclase, phosphates, and chromite) inside the shock veins were mostly transformed into their high-pressure polymorphs or were recrystallized as … WebA millimeter scale is shown. A chondrule (from Ancient Greek χόνδρος chondros, grain) is a round grain found in a chondrite. Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids. Because chondrites represent one of the oldest solid materials within the Solar System [1] and are ... dr mosley and flossing
