Keywords:Quenched indicator, Carbon-bearing grains, Extraterrestrial solidified process

Carbon-bearing grains called as quenched indicator of extraterrestrial rocks are required process applied for the accumulation of carbonaceous chondrites and carbon contents in rocky world. The presence of quenched carbon-bearing grains remained in the extraterrestrial meteorites indicates that the seawater-type fluid was not related with inactive global system totally .
