What ihe basis for the determination of Uranium 238-Lead radiometric date of 1120 ma for granite
Wouldn't it be the ratio of U238 and lead in the granite?
I do not think so, i have actually answer the question explaing it in words but i am not sure of it as the question is confussing
I take it this is S103 TMA08 Q2(b) (10 marks) "The age of a granite can be determined using radiometric dating. Explain the basis for the determination of a 238U-Pb radiometric date of 1120 Ma for a granite."
The key word here is "explain". There is nothing to calculate.
The best source of information is the course books.
