摘要:

Radioactivity measurements were made on Ngauruhoe lavas of various age, and also on xenoliths found in the Ngauruhoe flow of September 19S4. The variation in a count rates of the Ngauruhoe lavas erupted in 1954 is due to the presence of a varying amount of small feldspathic xenoliths or their absence. The radioactivity is roughly proportional to the potash content.
