Alkaline rocks are often associated with extensional tectonism and regards as the characteristic products occurring in continental margins or rift zones. They were usually generated in deep-large-fault zone and closely connected with basic/ultrabasic rock in space. Therefore, alkaline rocks are of significance in tectonic petrology. A set of Cretaceous alkali-rich syenite occurs in the Hongshan complex, at the southern Taihang Mountain, western Hebei Province. The studies of the Hongshan complex mostly focused on geology, petrochemistry and geochronological. But the mineralization in Hongshan complex has rarely been reported. Our recent investigation indicates that some potential Cu mineralization has close relation with the orthophyre. In this study, we presented new geological data and mineral isotopic composition for the minerals such as pyrites and chalcopyrite from ores rocks from the Hongshan porphyry Cu deposit and studied the source of ore-forming materials in order to predict the potential of the deposit.
