![]() Due to this data the assemblages of the Jenig Complex formed during the Permo-Triassic extensional event and cooled down in the Late Triassic to Early Jurassic. The final cooling below 400☌ and 300☌ occurred at 205±5 Ma and 185±5 Ma respectively, based on Ar-Ar muscovite and Rb-Sr biotite ages. EMS-dating of monazite yielded 275☒5 Ma, whereas a Sm-Nd isochron, including four whole rocks and three garnet fractions yielded 254☘ Ma. P-T calculations for three samples containing the assemblage garnet + andalusite + biotite + plagioclase + muscovite + quartz are ranging from 450 to 530☌ and 0.24 to 0.42 GPa. Garnet and staurolite show a continuous chemical zoning all other minerals are chemically unzoned. The mica schists are Alrich metapelites and characterized by the following mineral assemblage: St, Grt, And, Bt, Ms, Pl, Qtz, Chl, Ilm, graphite, Czoi, Mz, Ap, Zrn, Tur. Intercalations of up to a few meters thick garnet- and hornblende-bearing quartzschists as well as andalusite-bearing quartz veins are scarce. ![]() It consists of mica schists, quarzitic mica schists, quartzites and paragneisses. The Jenig Complex covers an area of about 1.5 km2 on the slopes of the valley directly north of Jenig. ![]() In this study the P-T-t evolution of the Jenig Complex (Austroalpine) which is part of the crystalline basement of the Gail valley (Carinthia/Austria) has been investigated. ![]()
