| monomict ureilite | is a kind of ureilite |  |
| has texture large, anhedral olivine and pyroxene grains |  |
| has intergranular boundary curved meeting in triple junctions |  |
| has gain size 1 mm |  |
| has plagioclase 0 % |  |
| ureilite | has letter designation AURE |  |
| has characteristic mineral olivine-pigeonite about 90% by volume |  |
| has matrix composition carbon, metal, sulfides small silicate grains along grain boundaries less than 10% by volume |  |
| has total mass of finds 9 kg (out of date) |  |
| has number of finds 6 (out of date) |  |
| has minerology olivine, pyroxene (some combination of pigeonite, orthopyroxene, augite) |  |
| has petrology coarse-grained granular |  |
| has likely origin partial melting residue |  |
| has olivine grain characteristic reduced rims contacting carbonaceous matrix material 0.1 mm FeO-free olivine and/or enstatite rims riddled with tiny inclusions of low-Ni metal |  |
| asteroidal achondrite | has origin asteroid |  |
| plutonic rock | has solidification mechanism cooling in deep underground chambers |  |
| has solidification timescale very slow |  |
| achondrite | has relative abundance 7.1 % of meteorite falls |  |
| has distinguishing feature no chondrules |  |
| igneous rock | has composition silicates (with very few exceptions) |  |
| meteorite | has fall date recorded by eyewitness or inferred from dating methods |  |
| has fall location strewn fields, elongated footprints which depends on impact angle, airbursts, and impact velocity |  |
| has fall coordinates in degrees, minutes and seconds of lattitude and longitude |  |
| has fall map which appears as an elongated footprint which depends on impact angle, airbursts, and impact velocity |  |
| can have crater image |  |
| has original mass which can over an order of magnitude greater than total mass of fragment(s) collected at the impact site |  |
| has impact velocity when it hits the ground which is smaller than its velocity before it enters the atmosphere |  |
| has impact angle |  |
| has weather resistance which depends on its composition |  |
| has monetary value large if the fall was witnessed |  |
| has name based on the locale, region, or nearby town in which the fall occurred |  |
| often produce power outages and failures in electrical equipment due to EMP (electromagnetic pulse) |  |
| can be associated with crater |  |
| vaporizes completely if size is between 3 micrometers and 3 millimeters |  |
| can survive fall if size is larger than 3 mm and velocity is less than 24 km per second |  |
| can survive fall if it fragments because smaller pieces with less mass are more easily slowed by the atmosphere |  |
| has ablative mass loss depending on composition, more friable stony meteoroids loses more mass than iron meteoroid |  |
| has ablative mass loss directly proportional to initial velocity |  |
| can shatter during impact phase |  |
| can fragment during meteor phase |  |
| has fragmentation probability during meteor phase which depends on composition |  |
| stony meteorite | has weather resistance low |  |
| has fragmentation probability high because it is more friable than iron meteorite |  |
| has ablative mass loss high because it is more friable than iron meteorite |  |
| rock | has part mineral |  |
| has genesis |  |
