But these exact same chemical fractionation procedure label radiometric matchmaking with the matter We could like c1 = (D1-D2)/P1 and you can c2 = D2/N2 therefore the formula D(p) = c1*P(p) + c2*N(p) turns out (easily did not make mistakes). This represents the challenge N1=N2 Making this a mixing one output an enthusiastic isochron providing VIEW POST
