To read the rest of the response, head on over to "Is radioactive dating affected by the age of the magma?"Once again, our feedback is about radioactive dating, which seems a major roadblock against Christians believing the world is the biblical age of 6,000 years. The basics are simple, but the process is complicated, and supporter Larry R wrote and asked about the issue.Hello,I have a question about radiometric dating. I understand how the process works, and the various assumptions that go into it. My question is, would the age of the magma have any bearing on the age of the rock created from it?Like, when Mt. St. Helen’s erupted in 1986, obviously we know when the rock was formed. If we were to send in various specimens for various testing, obviously the testing would indicate ages that are much larger than the actual age. My question is, do the isotopes (if any) in the lava/magma play a roll, and if so, how (or how not, if it doesn’t have any effect)?Thank you for your time.Larry R.CMI’s geologist Dr Tasman Walker responded (edited for the web):Hi Larry,Thank you for your email and your question.You said, “I understand how the process works, and the various assumptions that go into it.” I would not put it that way. I would say, “I understand how they say the process is supposed to have worked!”
