Název v původním jazyce

Multiple fluid sources/pathways and severe thermal gradients during formation of the Jilove orogenic gold deposit, Bohemian Massif, Czech Republic

Popis výsledku v původním jazyce

The Jílové deposit in the central part of the Bohemian Massif represents a vein to stockwork type of orogenic-type gold deposit. It is hosted by Neoproterozoic rocks of the Jílové Belt and by various magmatic dikes related to the ~355 to ~335 Ma CentralBohemian Plutonic Complex. The deposit offered an exceptional opportunity to trace O, C, S and Sr stable isotope evolution of parent fluids based on combined mineralogical and geochemical study of carbonate, quartz, scheelite, and sulfide minerals, whichrepresent six stages of mineralization, including the gold-bearing event. Age determination of hydrothermal muscovite (related to stage 2) via 40Ar/39Ar indicated an age of 339.0 +- 1.5 Ma for the quartz veins. The mineralization is essentially coeval with the late intrusive phases of the Central Bohemian Plutonic Complex (i.e. the ultrapotassic suite) and with late-orogenic large-scale tectonic movements at the boundary between the two crustal terranes (Teplá-Barrandian and Moldanubian
