Major carbonaceous matter in five C2 carbonaceous chondrites (Y-791198,Y-74662,Murchison, B-7904,and Y-793321) and six C3 carbonaceous chondrites (Allende, Y-790992,Y-791717,Y-81020,ALH-77003,and ALH-77307) was investigated by pyrolysis-gas chromatography. The amount of naphthalene produced on the pyrolysis varied largely from chondrite to chondrite, and the carbonaceous matter in these chondrites could be divided into five groups by the efficiency of formation of pyrolysis products. The groups did not accord with any conventional subdivisions of carbonaceous chondrites. The grouping based on the pyrolytic nature of the major carbonaceous matter may give additional information about secondary metamorphism in carbonaceous chondrites.
