Abstract
The rock-types of the ''Fluelagranatic Association'' can be classified as metamonzo- to metasyenogranites of S-type character. The different orthogneiss types bear a volcanic-arc signature. Sm-Nd-model-ages bet ween 1.2 and 1.7 Ga for several gneiss types indicate special crustal mixing processes.
