Abstract: A large number of lamprophyre dykes have been discovered in the Jiaodong area, but the genesis of lamprophyres and their relationship with gold mineralization in this region remain controversial. In this paper, nine lamprophyre samples from the Daliuhang Gold Mining Area were selected for systematic petrographic observation, whole-rock major, trace element analysis and zircon U-Pb geochronology. Zircon LA-ICP-MS U-Pb dating results show that the lamprophyres were emplaced at 125.7 ± 1.5 Ma, which is the product of magmatic activity in the Early Cretaceous. The lamprophyre samples are enriched in potassium, alkali, and aluminum, with Mg^# =64.8-73.3. They are characterized by enrichment in large ion lithophile elements (LILEs) and depletion in high field strength elements (Nb, Ta, Zr, Hf, Ti), but their trace element abundances differ by orders of magnitude from those of typical arc magmatic rocks. Combined with published Sr-Nd isotopic compositions, we infer that the mantle source of these lamprophyres were derived from ancient sub-continental lithosphere mantle that had been metasomatized, most likely by melts derived from carbonate-bearing sediments. The spatiotemporal coupling between large-scale mafic magmatism and giant gold deposits in the Jiaodong area suggests that mafic magmatism played a critical role in the gold mineralization process. The interaction between carbonate melts and their coexisting highly oxidizing fluids may have provided a crucial pathway for the dissolution and transport of gold within the magmatic system.
