摘要: Nine samples from the Monte Rosa Granite have been investigated by microscopic, X-ray, wet chemical, electron microprobe, stable isotope and Rb-Sr K-Ar methods. Two mineral assemblages distinguished optical methods dated as Permian mid-Tertiary means of age determinations. The assemblage comprises quartz, orthoclase, oligoclase, biotite, muscovite whereas Alpine microcline, albite+epidote or phengite.
