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 sle 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 weakly shock altered and has a shock stage of s2. feni is completely weathered whereas less than 5 percent of troilite is still present. therefore, the meteorite has a weathering grade of w4. magnetic susceptibility is log χ =4.75 (χ in 109 m3/kg) and, thus, consistent with a w4 h ordinary chondrite. here we report description of lut 009 in the first extended study on a meteorite from lut desert. along with this sle, inprogress investigations of other meteorites from the desert will open a window into the characteristics of meteorite concentrations in this region.
