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 کاملThe fall, recovery, orbit, and composition of the Tagish Lake meteorite: a new type of carbonaceous chondrite.
The preatmospheric mass of the Tagish Lake meteoroid was about 200,000 kilograms. Its calculated orbit indicates affinity to the Apollo asteroids with a semimajor axis in the middle of the asteroid belt, consistent with a linkage to low-albedo C, D, and P type asteroids. The mineralogy, oxygen isotope, and bulk chemical composition of recovered samples of the Tagish Lake meteorite are intermedi...

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),...
