Zijinshan ore field, Shanghang Co., Longyan Prefecture, Fujian Province, China

Neoproterozoic phyllites and metsandstones, unconformably overlain by Devonian to Carboniferous shallow marine sediments with minor limestone, containing Fe, Mn, Pb, Zn & Cu mineralization on limestone-sandstone contacts. Following Triassic tectonism, these were intruded by Jurassic granites and composite stocks, and related volcanics, followed by an extensive Cretaceous volcanic suite controlled by a major NE trending deep fault zone.
Copper-gold mineralization in the Zijinshan district is developed within the 125 ±4 Ma Shimaoshan volcanics and related intrusives in a small fault bounded volcanic basin where the dacitic volcanic dome complex was formed. Dacitic porphyry occurs in a pipe like intrusion in the centre of the basin, surrounded by dacitic volcanic breccia, tuff and lava. A system of circular and radial faults and fissures, developed around the dacite porphyry pipe, are typically filled by hydrothermal breccias and veins.
