H\u2010 and L\u2010chondrites are the most abundant meteorites in all collections, and many authors used the H\/L ratio as a characteristic parameter in comparing meteorite populations. H\/L ratios (after pairing) vary from 0.90 in observed falls up to 1.74 in El M\u00e9dano (Atacama Desert). In this study, we investigate the H\/L ratio of 965 unpaired H\u2010 and L\u2010chondrites collected in Oman and compare this population with observed falls and other hot desert collections. We find a mass dependence of the H\/L ratio among hot desert finds and identify mechanisms such as fragmentation during weathering and fall that have an impact on the H\/L ratio. We employ the Kolmogorov\u2013Smirnov and Mann\u2013Whitney U statistical tests to compare the mass distributions of H\u2010 and L\u2010chondrites and to test the relationship between the similarity of mass distributions and the H\/L ratio. We conclude that the variations of the H\/L ratios observed in various populations are a sampling artifact resulting from secondary effects and observational bias, expressed in differences of the H and L mass distributions which are not observed in falls, and not due to variations in H\/L of the meteorite flux. The H\/L ratio of 0.90 observed among recent falls is considered as most representative for the overall meteorite flux, at least since the Late Pleistocene.”<\/p>\n","protected":false},"excerpt":{"rendered":"
