meteorite find which depends on its composition during meteor phase which depends on composition based on the locale, region, or nearby town in which the fall occurred can be severe due to long exposure time to environmental corrosion agents lower because the fall was not witnessed 485755 kg often minerals not found on Earth meteorite when the meteorite was found 1691 meteoroid from interplanetary space or fragment dislodged from another planet, moon or planetesimal directly proportional to initial velocity a meteorite whose fall was not witnessed

polymict ureilite low olivine, pyroxene (some combination of pigeonite, orthopyroxene, augite) no chondrules high because it is more friable than iron meteorite reduced rims contacting carbonaceous matrix material 0.1 mm FeO-free olivine and/or enstatite rims riddled with tiny inclusions of low-Ni metal partial melting residue cooling in deep underground chambers based on the locale, region, or nearby town in which the fall occurred AURE 7.1 % of meteorite falls 9 kg (out of date) bre - chia smaller mineral fragments, carbon, suessite (Fe3Si), sulfides, minor chromite and minor apatite olivine-pigeonite about 90% by volume silicates (with very few exceptions) polymict breccia 6 (out of date) asteroid high because it is more friable than iron meteorite very slow common in clasts typical monomict ureilite material plus a variety of other lithic clasts fragmental breccias containing lithic clasts of typical monomict ureilite material plus a variety of other lithic clasts coarse-grained granular
