: thorogenic lead 中的"thorogenic"是什麼意思
: 查了好久 查不到
: 它又跟鉛的同位素有什麼關係
: 煩請知道的人幫忙解答一下
: 感謝感謝
What you are asking is anthropogenic lead, I think.
It means any Pb which is not produced by natural radioactive decays.
The reason geochronologists don't like it is because it confuses and
screws up your data. Most of terrestrial samples are contaminated by
anthropogenic lead, which is pretty bad.
