Results are presented from an investigation of 11 non-Antarctic ordinary chondrites. The porosity of the chondrites is less than 20 percent, indicating that some mechanism acts to lower the porosity of chondrite parent bodies, if such objects originated as aggregates of dust. The elastic and thermal properties of ordinary chondrites vary markedly with porosity. It is thought that cracks originating in impact events are abundant in chondrites. Another finding is that elastic wave velocities correlate fairly well with thermal properties. For H chondrites, porosity declines with increasing metamorphic temperature, that is, petrologic type. This indicates that a compaction of aggregated dust is prompted by a raised temperature. The absence of an obvious correlation between porosity and petrologic type for L chondrites may mean that they have been modified by other events after their formation. No significant difference is found between the physical properties of Antarctic and non-Antarctic chondrites.
