Plate zone Explanation: Reasonably certain- I've been out of exploration geophysics for quite a while now after over 30 years of it. This must be something to do with plate tectonics (Palaeozoic or Hercyninian) in Austria (Lisabichl) -------------------------------------------------- Note added at 1 hr (2013-10-14 13:34:47 GMT) -------------------------------------------------- Hi Barbara, something like this, perhaps: "The Katschberg quarz-phyllite represents a progradient, metamorphic, strongly graphitically pigmented, sericite-chlorite-quarz-phyllite series of variable thickness which contains layers and plates of banded calcareous marbles, mica-rich marbles and dolomites with ankerite inclusions (ferrous dolomite – Lisabichl plate zone)" -------------------------------------------------- Note added at 2 hrs (2013-10-14 14:44:47 GMT) -------------------------------------------------- I've been out of this too long - I think it should be quarzite-Phyllite, rather than quarz-phyllite. -------------------------------------------------- Note added at 2 hrs (2013-10-14 14:46:54 GMT) -------------------------------------------------- Typing's lousy, too! Quartz is, of course, with a "t" quartzite-phyllite -------------------------------------------------- Note added at 4 hrs (2013-10-14 16:12:55 GMT) -------------------------------------------------- New reference and examples: Source: Aspects of Geology in Austria and Adjoining Areas: Introduction FRANZ NEUBAUER & VOLKER HOCK 2) Work by various groups on paleogeographic relationships, specifically in Paleozoic successions, led by Helmut W. FLÜGEL and Hans-Peter SCHÖNLAUB, gave a more detailed understanding of the Paleozoic microplate puzzle Several stages of accretion of continental microplates were associated with the consumption of older, Tethys-derived, as well as newly formed ocean basins between the Triassic and Neogene. |

Schollen slices Explanation: should fit (Lisabichl Schollenzone - Lisabichl zone of slices). For 40 km on either side of Motagua River Valley lies a complicated boundary zone of fault slices between the two blocks where high-P/T rocks occur: http://research.amnh.org/users/gharlow/IGCPman-PreP.pdf The Rosman Fault marks the sharp tectonic contact between the Chauga Belt and the Blue Ridge belt within the Brevard Zone. It contains relatively unmetamorphosed slices of carbonate and shale: http://geo.ua.edu/field-trips/field-trips/brevard-fault-zone... The fault zone consists of several structural slices of rocks of differing degrees of metamorphic modification: http://www.otago.ac.nz/geology/research/gold/otago_north_eas... Fault-bounded slices of mafic and lesser ultramafic rocks lie along the northeast edge of Alexander Terrane south of Kluane Lake in the Slims River area: http://www.geology.gov.yk.ca/metallogeny/kluane/ Chatham fault: A reinterpretation of the contact relationships between the Giddings Brook and Chatham slices of the Taconic allochthon in New York: http://geology.gsapubs.org/content/4/1/56.abstract The quartzphyllite described by former authors can be divided into two parts: The Lower-Paleozoic phyllite with pyritebearing blackschists and the Permian carbonaceous phyllite associated with alpine Verrucano. The Triassic, in Radstadt Tethian facies, overlies transgressively the gneiss-lamella of Weisspriach (region of Gurpitscheck near Ulnhütte, figure 1). Therefore this gneiss-lamella is part of the Radstädter Dekkensystem. Staurolite-garnet bearing micaschists which form synclines were found along the southern rim of the Schladminger Gneisdecke (figure 2). The basis of Nock-Kristallin, which overlies the window of Hohe Tauern consists of a big diaphthoritic zone (regressive metamorphism). Here the rocks are phyllitic garnet-micaschists with slices of rather "sound" garnet-micaschists and gneisses (selective retromorphism). They are overlain by an alternating succession of staurolitegarnet bearing micaschists and paragneisses (biotite-andesine/oligoclase-gneisses) which show the relatively well preserved pre-Triassic metamorphic crystallization in amphibolite facies: http://www.landesmuseum.at/pdf_frei_remote/JbGeolReichsanst_... -------------------------------------------------- Note added at 7 Tage (2013-10-21 12:43:51 GMT) Post-grading -------------------------------------------------- gerne & viel Erfolg! |
