Abstract
A chemical separation method of Hf from rocks is presented. A procedur e involving three stages of ion-exchange columns and sulfuric acid as an eluant produces consistent Zr- and Ti-free Hf separations. The meth ods described are well suited for high-Ti samples, such as mafic rocks . In addition, the method provides a very efficient means for Hf separ ation from zircons.
