Table 9
Model results for the percentage of volume in the parent body of L chondrites occupied by material that suffered the range of metamorphic temperatures corresponding to petrologic types three to six for different models, observed percentages for H meteorites (falls and falls + finds), and maximum metamorphic temperatures of the petrologic types used by the different authors for calculating volume fractions.

Notes. (a) Key to models see Table 8. Model HM is for the H chondrite parent body determined in the same way as described inthis paper, but using data for H chondritic material and meteoritic data as given in Henke et al. (2013). (b) Values correspond to the model of the compacted body that is closest to our preferred model. (c) Estimated from their Fig. 9. Petrologic type four and five are not discriminated. (d) Data from the Meteoritical Bulletin Database https://www.lpi.usra.edu/meteor/metbull.php.
