Measurement has been made of Ir content in samples collected from lower Triassic layer in Gifu, central Japan, rich in fullerenes, in order to investigate if they are correlated with extraterrestrial events. The coincidence gamma ray measurement method has been applied to the samples after they had been activated by a research reactor at Japan Atomic Energy Research Institute and had been cooled for 2 months. The samples analyzed yielded Ir content at several ppt's, far less than those of the K/T boundary layers, for which Ir content of a few ppb's has been obtained. In view of other experiments that yielded negative results, it is concluded that the fullerenes are not to be taken as evidence of extraterrestrial events.
