Abstract
The chemical and mineralogical experiments carried on pieces of eight different meteorites to analyze the impact disruption were discussed. Experiment carried showed that the average composition of the Interplenatary dust particles (IDPs) might be biased towards the composition of the matrix of the parent body while the average composition of the polar micrometeorities may be more heavily weighted towards the composition of the chondrules and clasts. The threshold collisional specific energy for the chondritic meteorites was found to be 1419 J/kg. Analysis suggested that the inhomogeneous asteroid should be sampled at size scale significantly larger than the largest subunit to provide a representative bulk chemical and mineralogical characterization.
