Short summary
Aluminum-rich granulites from Austria contain large garnets with kyanite inclusions. Garnets are built up from compositionally different types. They are replaced partially by various symplectites. Thermodynamic analysis points to metasomatic alteration and rock decompression due to tectonic transport at high temperatures from deep to middle crustal levels. The various symplectites were formed after decompression during cooling within a short time interval of less than 500 years.
