You’re a geologist who is about to stake claim to a diamond deposit, but first you need to know the age of the metamorphic rocks in the area. In your lab, you measure headsium and tailspin in the metamorphic rock/fossil sample and discover that one eighth of the headsium remains.
1) how many half lives have passed?
2) if the half life of the headsium were 150 million years, how long ago did the fossil in the metamorphic rock die?? Show your work.
No links please.
