Among OCs, Antarctic finds conform more closely to Benford\u2019s law than observed falls, Northwest Africa (NWA) finds, or Oman finds mainly because Antarctic OCs tend to be relatively unweathered (and mostly intact) and have not been aggregated as pairs under collective meteorite names. Deviations from Benford\u2019s law can result from tampering with data sets. The set of OC falls reflects tampering with the original Benford distribution (produced by meteoroid disruption) by the deliberate aggregation of paired individual samples and inefficiencies in the collection of small samples. The sets of NWA and Oman OC finds have been affected by natural \u201ctampering\u201d of the original distributions principally by terrestrial weathering, which can cause sample disintegration. NWA finds were also affected by non\u2010systematic collection of samples influenced by commercial considerations; collectors preferred type\u20103 OC as revealed by the high proportions of such specimens among NWA chondrites relative to those among falls and Oman and Antarctic finds. The percentage of type\u20104 OC among falls is appreciably lower than in the sets of finds. This suggests that type\u20104 chondrites are friable and disintegrate into numerous pieces; these are counted individually for the sets of finds, but collectively for falls. However, the fact that the percentages of type\u20103 OC are not generally higher for finds may be that these samples tend to break into small pieces that are preferentially lost.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Alan E.
