Granitic porphyry dykes, ranging from 1 to 5 m in width, primarily intrude into the Jingzhushan Formation and Xiala Formation limestone with minor intrusion into the conglomerates. They are spatially adjacent to extensive exposures of Early Cretaceous granite, approximately 1–2 km away. These dykes exhibit an irregular radial distribution, extending 500 m to 1000 m. Locally, the intrusion boundaries are distinct, displaying significant magmatic intrusion chill zones, and are accompanied by weak copper mineralization. The dyke width can reach up to 5 m or wider in some areas, with local occurrences as stocks.
