Geochemistry of the Precambrian metamorphic rocks from the central Sobaegsan Massif, Korea

The basal metamorphic complex of the central Sobaegsan Massif consists of pelitic & psammitic paragneisses, various kinds of granitic gneisses and lesser amounts of amphibolite. The granitic gneisses could be clearly distinguished from the pelitic and psammitic paragneisses on the basis of major-element geochemistry. A number of geochemical plots reveals that granitic gneisses were derived from calc - alkaline igneous rocks.
