Meteoritic chondrules and the Weibull function

Chondrule mass frequency distributions determined from the Bjurböle, Chainpur, Allegan, Saratov, Elenovka and Nikolskoe meteorites have been tested to see if they could be fitted to either the Rosin or Weibull statistical functions. Whereas none of the distributions gave a fit to Rosin's law, they could all (with the exception of Nikolskoe) be fitted to the Weibull function suggesting similar origins and/or histories. Although it is possible to produce a Weibull distribution from a Rosin distribution by the removal of lower mass particles, it is easier to envisage the Weibull mass distribution of meteoritic chondrules as a feature of the chondrule-forming event or of material from which they formed.
