radiogenic nature of argon-40 in the oldest biotites of the kola peninsula
Creators
Description
It is shown by three graphical methods that ancient biotite aged 5.1.109 yr. and older does not contain excess 40Ar and that the whole 40Ar was formed via radioactive decay of 40K present in the minerals. It is suggested that due to variation in the force of gravitational interaction with the age of the universe, the K-decay of the 40K nucleus slowed down, which indeed is the cause of enhanced age of the Kola biotite
