Lut 009, an H4 (S2, W4) ordinary chondrite meteorite from Lut Desert of Iran
Lut 009 meteorite was found during a trip to Lut Desert of Iran in March,2012, at 30°20.38' N, 59°09.04' E. Chemical compositions of equilibrated olivine (Fa19.3 ± 0.5) and orthopyroxene (Fs16.7 ± 0.6) show that the meteorite sample belongs to H group of ordinary chondrites, while the texture (chondrule petrography and plagioclase size) suggests a petrologic type of 4. The Lut 009 has been very...

متن کاملOrdinary 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 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...
