The flux of meteorites to the Earth over the last 50 000 years

Monthly Notices of the Royal Astronomical Society (1996)

P. A. Bland Thomas Smith A. J. T. Jull Frank J. Berry A. W. R. Bevan

98 ordinary chondrite finds, terrestrial age-dated using 14C analyses by Jull et al., from three arid/semi-arid meteorite accumulation sites (New Mexico, the Sahara, and the Nullarbor Region, Australia) have been examined by Mössbauer spectroscopy to determine quantitatively the terrestrial oxidation for each sample. A comparison of weathering over time, and its effect in 'eroding' meteorites, allows a calculation of a decay constant for meteorites from each hot desert site. This, together with the number and mass distribution of paired meteorites in each region, enables us to derive estimates of the number of meteorite falls over a given mass per year: we calculate between 36 and 116 falls over 10 g per 106 km2 yr−1. In addition, we constrain the total mass flux to the Earth's surface over the 10 g to 1 kg interval to between 2900 and 7300 kg yr−1. We find remarkable agreement in our estimates from each accumulation site, and also with the estimate of the present flux made from MORP camera network data presented by Halliday, Blackwell & Griffin, suggesting that the flux of meteorites to the Earth has remained essentially constant over the last 50 000 yr. This work is the first independent confirmation of the MORP estimate, and indicates that meteorite accumulation sites provide an alternative method of calculating flux. We suggest that the application of a similar methodology to the Antarctic meteorite population may be used to explore the possibility that the flux of meteorites to the Earth has varied over the 1-Ma time-scale sampled by these meteorites.

Mineralogy, petrology, geochemistry, and chronology of the Murrili (H5) meteorite fall: The third recovered fall from the Desert Fireball Network

Meteoritics and Planetary Science (2021)

Seamus Anderson G. K. Benedix L. V. Forman Luke Daly R. C. Greenwood

Abstract Murrili, the third meteorite recovered by the Desert Fireball Network, is analyzed using mineralogy, oxygen isotopes, bulk chemistry, physical properties, noble gases, and cosmogenic radionuclides. The modal mineralogy, bulk chemistry, magnetic susceptibility, physical properties, and oxygen isotopes of Murrili point to it being an H5 ordinary chondrite. It is heterogeneously shocked (S2–S5), depending on the method used to determine it, although Murrili is not obviously brecciated in texture. Cosmogenic radionuclides yield a cosmic ray exposure age of 6–8 Ma, and a pre‐atmospheric meteoroid size of 15–20 cm in radius. Murrili’s fall and subsequent month‐long embedment into the salt lake Kati Thanda significantly altered the whole rock, evident in its Mössbauer spectra, and visual inspection of cut sections. Murrili may have experienced minor, but subsequent, impacts after its formation 4475.3 ± 2.3 Ma, which left it heterogeneously shocked.
