Ordinary Chondrite Micrometeorites from the Koronis Asteroids
Introduction: Micrometeorites (MMs) are large (>25 µm) interplanetary dust particles that survive atmospheric entry to be recovered from the Earth's surface. Amongst those particles that escaped significant heating during atmospheric entry two groups have been identified [1]: (i) fine-grained MMs (fgMMs), which are similar to the fine-grained matrices of hy-drated carbonaceous chondrites (CCs),...
متن کاملPost-shock Annealing and Post-annealing Shock: Implications for the Thermal and Shock Histories of Ordinary-chondrite Parent Bodies
A common view of the thermal and shock histories of ordinary-chondrite (OC) parent bodies is that, for the most part, thermal and shock metamorphism were distinguishable and successive events; e.g., the decay of 26 Al heated chon-dritic planetesimals and subsequent impacts produced various shock effects. Although collisions have long been acknowledged as capable of producing significant heating...
متن کاملOrganic compounds in the Forest Vale, H4 ordinary chondrite.
We have analyzed the H4 ordinary chondrite Forest Vale for polycyclic aromatic hydrocarbons (PAHs) using two-step laser mass spectrometry (L2MS) and for amino acids using a standard chromatographic method. Indigenous PAHs were identified in the matrices of freshly cleaved interior faces but could not be detected in pulverized silicates and chondrules. No depth dependence of the PAHs was found i...
متن کاملOlivine Microstructures in the Miller Range 99301 (ll6) Ordinary Chondrite
Introduction: Miller Range 99301 (MIL 99301) was classified as an LL6 ordinary chondrite based on its recrystallized texture in thin section, chemical homogeneity of olivine and low-Ca pyroxene grains, and the presence of coarse (>50 μm) interstitial grains of plagioclase [1]. Determination of shock stage was problematic as various shock indicators gave contradictory information: olivine and pl...
