Homework Statement
Learning about lead-lead dating to determine the age of things (specifically the solar system using meteorites)... I can't seem to understand what the meaning of "common lead" is. So far the best I'm getting is that it is some sort of contaminant.
What is the relationship/difference between the common lead, radiogenic lead that was formed from decay, and initial lead abundances. Is it the same as an initial lead abundance? I'm confused.
