Multiple episodes of magmatic and hydrothermal activity at the Radzimowice gold deposit in the Sudetes Mountains (Bohemian Massif, Poland)

摘要

The Radzimowice Au-Cu-As deposit occurs in the area of the Zelezniak Intrusion (ZI), which consists of multiple intrusive phases emplaced during the Upper Carboniferous. Geochemical characteristics of subalkaline to alkaline igneous rocks indicate a subduction-related post-collisional arc setting. Lampro-phyre dykes, pre-dating ore mineralization and are spatially related to the quartz-sulfide veins, and characterized by a high concentrations of mantle-compatible trace elements. The economic ore mineralization has resulted from several hydrothermal stages. Early mesothermal quartz -
