If numerical dating of rock unit A gave a crystallization age of 1.2 billion years, and numerical dating of rock unit F gave a crystallization age of 500 million years, then how old is rock unit E?
What will be an ideal response?
Answer: Rock unit E would have to be younger than F, so it's younger than 500 million years old. The information about A's age is superfluous.
