Abstract The northern part of Xiaohongshan, located in the middle of Eastern Kunlun metallogenic belt, mainly belongs to the Xueshanfeng-Buerhanbuda Variscan-Indosinian Co-Au-Cu and jade metallogenic belt, with favorable ore-forming geological conditions. Both stream sediments and soil geochemical survey show high intensity of Au anomalies. The gold mineralized bodies are mainly occurred in the Ordovician-Silurian Nachitai Group, including carbonate rock assemblage, metamorphic detrital rock assemblage and acidic-intermediate volcanic rock. The stream sediments from anomaly areas Hs65 and Hs93 show obvious three-level zoning with high anomaly intensity. The 1:10 000 soil survey reveals high soil anomaly intensity of Au, Cu, As and Sb, with overlapped anomaly curves. One gold orebody and six mineralized bodies are verified and controlled by surface trenching engineering. With comprehensive analysis on the ore-forming geological conditions and geochemistry in northern Xiaohongshan, it is promising to find gold deposits with further exploration in the study area.
