The H contents of quartz from alpine veins from the penninic rocks of the central and western Tauern Window (Austria/Italy)

Abstract

The hydrogen content of 29 quartz crystals originating from the Penninic series of the central and western Tauern Window (Tyrol, Austria) was determined by IR spectroscopy. The hydrogen contents are between 7 and 66 H/106 Si-atoms. In one sample showing a mimetic lamellar structure H-contents up to 140 H/106 Si-atoms could be found. In most cases no difference exists between the hydrogen contents of margins and cores of the crystals. No clear relationships between the hydrogen content of the quartz lattice and the metamorphic temperature ranging from about 600°C to about 450°C can be found.
