Distribution of gold mineralization in the Recsk ore complex, NE Hungary

Abstract

The Lahoca and Recsk Deep ore complex was formed in relation with andesite volcanics and diorite porphyry intrusives of Paleogene age. The zone is long known for significant enrichment of Cu, Pb and Zn ores. The presence of gold was recorded in the early years of the Lahoca mine. Epithermal and mesothermal gold enrichments are both known in the ore complex. In the epithermal zone low and high sulfidation varieties were identified on the volcanic level of the complex. In the mesothermal zone, significant gold enrichment was indicated in the porphyry copper and skarn copper, zinc ore zones and Pb-Zn veins. In the high sulfidation and the mesothermal copper skarn ore types a moderate correlation between Au and Cu was recorded.
