Assignment:
Steponaitis, Blackman, and Neff (American Antiquity 61:555-572, 1996) use the following correction for bulk elemental concentrations measured in shell- tempered pottery: e' = (1000000*e)/(1000000-2.5Ca), where e' = corrected elemental concentration, e = originally measured elemental concentration, Ca = concentration of calcium, and all measurements are in parts per million (ppm). Explain how this correction works. Hint: Assume that the shell temper is pure calcium carbonate, CaCO3.
Provide complete and step by step solution for the question and show calculations and use formulas.
