Abstract:The geotectonic location of the Bulunkou area is in the Tianshuihai terrain,belongs to the Bulunkou-Sangzhutage Iron-copper-gold Metallogenic belt. More than 20 Iron-copper-gold deposits and mineralization sites have been discovered in the area, showing great potential for prospecting. The deposit occurs in the carbonate rock formation, and is later superimposed by structural hydrothermal fluid. It is a sedimentary metamorphic and late hydrothermal reformed layered deposit. The deposit as a whole reflects the characteristics of strata mineralization, structural ore-control, hydrothermal reform and multi-stage mineralization. In this paper, the author based on the comprehensive analysis of strata, structures, magmatic activities and orebody characteristics in the area, and by analogy with typical deposits, summarize metallogenic regularity and analyze prospecting potential. We proposes prospecting indicators such as strata lithology, geological structure, hydrothermal alteration and geochemical anomalies. And we preliminarily believe that this area has good prospects for finding large contact metasomatic, magmatic hydrothermal copper deposit and oversized sedimentary modified iron deposit.
