Abstract
The Maggia-Lappen is a medium-grade Pennidic series of polymetamorphic gneisses, schists, and amphibolites, with some aplitic and pegmatitic veins. The sequence of Alpine recrystallization of the chief constituents of the series is the following: Accessories — common hornblende — zoisite + clinozoisite + pistacite — mica — potash feldspar + quartz — albite + quartz — oligoclase + quartz — andesine-labrador + quartz — quartz. This sequence is characteristic of medium-grade metamorphic rocks of sedimentary and metasomatic origin which have never been subjected to juvenilemagmatic conditions.Keywords
