Noble gas elemental and isotopic compositions of magnetic fractions separated from four Pacific Ocean deep sea sediments using a step heating technique have been measured in order to investigate the origin of extraterrestrial noble gases. A constant Ne-20/N-22 ratio of (1.8 + or - 0.4) x 10 to the -4th was found in all the samples. The results imply the existence of extraterrestrial Ar, but only a negligible quantity of spallogenic Ar. It is suggested that the extraterrestrial noble gases are implanted solar flare particles. It is noted that the present uniformity of isotopic ratios of He and Ne can be explained both by a grain size sieving effect of interplanetary dust particles during atmospheric entry and by the subsequent diffusion loss of shallowly implanted solar wind noble gases.
