Origin and metamorphic evolution of Fe-Mn-rich garnetites (coticules) in the Desná Unit (Silesicum, NE Bohemian Massif)

Original language description

The Fe-Mn-rich garnetites (coticules) associated with banded iron formations occur in the Neoproterozoic metamorphic complex of the Desná Unit. Their mineral assemblage consists of almandine-spessartine garnet, quartz, magnetite, epidote and sporadicallybiotite, chlorite, amphibole, plagioclase, calcite, ilmenite and apatite. The mineralogical, petrological and geochemical results demonstrate that the protolith of coticules and associated BIFs was formed during periods of submarine hydrothermal activity in the Late Proterozoic by differential precipitation of Fe and Mn from low-temperature solutions. The Fe-Mn-rich precipitates mixed to a varied degree with the detritic siliciclastic material. Subsequently the protolith underwent polyphase metamorphism reaching the amphibolite facies grade during the pre-Variscan (M1) and Variscan periods. The P-T conditions assumed for the peak Variscan metamorphism (M2) are T ?540-580 °C and P ?600 MPa, the M3 is characterized by an upper pressure l
