Chalcopyrite copper during hydrothermal circulation. Chalcopyrite is concentrated in this environment via fluid transport. Porphyry copper ore deposits are formed by concentration of copper within a granite stock during the ascent and crystallisation of a magma. Chalcopyrite in this environment is produced by concentration within a magmatic system. Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide-saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid. Chalcopyrite is the most important copper ore. Chalcopyrite ore occurs in a variety of
Central Ore Mountains valley of the Schwarzwasser and, below its mouth, by the Zwickauer Mulde. The upper regions of the Central Ore Mountains are part of the Ore Mountains/Vogtland Nature Park. Central Ore Mountains The Central or Middle Ore Mountains ( or "Mittelerzgebirge") is a natural region that forms the central-western part of the Ore Mountains in the German federal state of Saxony. It is part of the overarching unit, the Saxon Highlands and Uplands. It forms the eastern part of the former major units, the Lower Western Ore Mountains ("Unteres Westerzgebirge", 423) and Upper Western Ore Mountains ("Oberes Westerzgebirge", 421) and is
