内容記述 | We measured the He content and the ^3He/^4He ratio of a K-T boundary clay from Hokkaido. If some meteoritic debris which escaped total melting or evaporation at the K-T event remains in the clay, it may be possible to observe some ^3He in it. However, we could determine only the upper limits of the ^3He/^4He ratois (<6.2×10^<-6> for a bulk sample) because of the small amount of ^3He. Three alternatives are considered to explain the result. | |||||
