WebIf each isotope was in equal proportions (eg. each made up 50%) that would work, but that isn't the case here. One isotope makes up ~99% of all carbon, the other makes up ~1%. Clearly the isotope that makes up 99% needs to be given more importance. There is more than one way to take an average. WebOne of the isotope pairs widely used in geology is the decay of 40 K to 40 Ar (potassium-40 to argon-40). 40 K is a radioactive isotope of potassium that is present in very small amounts in all minerals that have potassium in them.
