Regolith breccias that were formed on the surface of asteroids often contain carbonaceous chondrite-like clasts. In this report, mineralogical features of the carbonaceous chondrite clasts in H chondrite regolith breccias are compared with those in howardites and those of micrometeorites. Most of the clasts in H chondrite regolith breccias contain only saponite or saponite and serpentine as phyllosilicates. Clasts that contain only serpentine as phyllosilicates are relatively minor. This tendency is similar to that of phyllosilicate-rich micrometeorites. However, among the carbonaceous chondrite clasts in howardites, CM chondrite-like clasts are the most abundant and CI chondrite-like clasts are less abundant than CM-like ones.
