Origin of fragmental and regolith meteorite breccias - Evidence from the Kendleton L chondrite brecciaNine specimens of the Kendleton L chondrite, chosen (from the total of 52 that were inspected) for the presence of a wide variety of clasts, were studied microscopically as well as by EMPA with the purpose of investigating the origin of regolith and fragmental meteorite breccias. The results indicate that Kendleton does not contain detectable amounts of solar-wind gases. The Kendleton clasts were found to include a wide variety of L3, L5, shock-blackened, and melt rock clasts, which are considered to have originated from normal L chondrite material, and a unique tridymite-rich inclusion. The results suggest that meteoritic regolith breccias may have different origin from that of lunar breccias.
