New evidence of blueschist facies rocks and their geotectonic implication for Variscan suture(s) in the Bohemian Massif

Popis výsledku v původním jazyce

Blueschist facies rocks, exposed within consolidated continental blocks, provide some of the best evidence for the existence of previous suture(s). They usually occur as lenses or layers embedded within greenschist or amphibolite facies rocks and indicate reequilibration at medium- to low-pressure conditions. In the Bohemian Massif, a few occurrences of blueschists have been reported, and here new evidence of high-pressure metamorphism in various lithologies is presented that suggests a larger extent ofblueschist facies rocks along the northern border of this Massif. An earlier blueschist facies metamorphism is documented by inclusions of glaucophane in garnet, epidote, and titanite from metabasites along with zoned white mica having a phengitic coreand a muscovite rim in metapelites and orthogneisses. The estimated P-T conditions, obtained using pseudosections and mineral isopleths, correspond to blueschist and low-temperature eclogite facies conditions (1.1-2.0 GPa at 350-550 oC).
