This may be more of an age-dating question. When a meteorite travels through the Earth's atmosphere, I assume that it gets really hot. Is the temperature of reentry hot enough to effect the radiometric dating process? Does heat influence the quality of radiometric dates, or does the rock have to completely melt to "reset to clock"?
I have found similar questions on Earth Science:
- How can radiometric dating of meteorites determine the age of the earth? Wouldn't this only determine the age of the decaying nuclide in each rock?
- Why is Earth's age given by dating meteorites rather than its own rocks?
- How do we know the asteroids formed at the same time as earth?
But those don't quite answer the question I have.
