Abstract
In studying contact phenomena between different types of rocks, it is important to analyze (small) samples from the contact zone for a combination of major and trace elements. This has been done in a recent study of the metamorphosis of quartzite into granite in eastern Sweden.1 Important major elements are Na, Al, K, Fe and Mn, but the trace elements Cr, Co, Rb and Cs have also been determined. Another investigation to which this principle has been applied concerns the mutual relation of a group of ultrabasic rocks in central Greece. The most important elements here are Na, Al, K, Sc and Cr.2 Four routine determinations which are used in this type of studies are presented here.
