Isotopic analysis of foraminifera shells: Interference from chemical treatment
Abstract Foraminifera shells were soaked in solutions of formalin, ethanol, tetrachlorethylene and hydrogen peroxide; also, crushed Solnhofen Limestone was exposed to formalin. Formalin treatment caused a significant change in the results of stable isotope analysis. The effect is interpreted as a result of partial dissolution. Soaking other than those with formalin did not affect isotopic analysis.
