Abstract: Located in the Luanchuan ore concentration area of the East Qinling molybdenum belt, the Chennangou molybdenum deposit lies on the south side of Luanchuan fault and belongs to the North Qinling fold system. Combining ore-forming geological environment in the ore district with soil geochemical characteristics, the authors evaluated the soil geochemical element association in the area by using the index of geoaccumulation. On the basis of a comprehensive analysis, favorable exploration targets were delineated, and field inspection and engineering verification were carried out. The results show that the Chennangou molybdenum deposit is a hydrothermal deposit related to Laojunshan granite rock, and both the edge and the outer contact zone of Yanshanian Hongyanzhai granite rock are favorable positions of molybdenum enrichment. In addition, the small NE-trending structure played a certain role in the formation of molybdenum ore. This study not only improves the research on the hydrothermal deposit related to granite rock but also has some significance for further exploration in the Luanchuan ore concentration area.
