Olivine 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...

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...

Microscopic Magnetic Study of Ordinary Chondrite Using Magneto-optical Imaging

Fe-Ni alloys, which are kamacite (<10 wt% Ni), taenite (30 ~ 40 wt % Ni), and tetrataenite (ordered Fe 50 Ni 50), are the dominant magnetic minerals in the metamorphic (type 5-6) ordinary chondrites [1], and the carrier of the remanent magnetization is high coercivity tetrataenite [1,2,3]. Metallographic studies reported that there are two types of Fe-Ni grains in the metamor-phic ordinary chon...

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),...
