Scientific paper
The dependence of the (mass) density of chondrules on chondrule size is investigated for chondrules from the Bjurbole meteorite. One hundred seventy six very nearly spherical chondrules with diameters between 0.3 and 3.2 mm were sorted from over 3000 chondrules disaggregated from Bjurbole, and the mass of each was determined by a microforce balance. A plot of the density of the chondrules against their diameters reveals that the density decreases as the chondrules get larger. Correlation analysis confirms this result and indicates that the density decreases steadily as the size of the spherical chondrules increases. An expression for the relationship between chondrule size and density is determined by a linear regression fit of the data, and it is suggested that the density decrease is related to compositional differences.
