Abstract: The Shuangmiaoguan gold deposit from the Macheng City, Hubei Province is in the Dabie orogenic belt. Significant prospecting progress for this gold deposit has been achieved in recent years. However, the ore−forming age and geodynamic setting of this deposit remain unclear. The Neoproterozoic gneissic monzogranite and meta−gabbro are pervasive in the mining area. Eleven gold orebodies have been discovered in the NE, NNE and NNW−trending faults. The field investigations show that the intrusions of K−feldspar granite and granite porphyry in the north of Shuangmiaoguan gold deposit were cut by NE−trending ore−bearing faults, and the diorite dikes from the middle section of gold deposit interpenetrate across the ore bodies.suggests. Zircon U−Pb ages of the K−feldspar granite, granitic porphyry and diorite dikes are (133.6±1.1) Ma, (127.9±1.6) Ma and (126.6±1.3) Ma, respectively. Additionallly, field investigations show that the intrusions of K−feldspar granite and granite porphyry in the north of Shuangmiaoguan gold deposit were cut by ore−bearing faults, and the diorite dikes from the middle section of gold deposit interpenetrate across the ore bodies. This suggests that the Shuangmiaoguan gold deposit should be formed between 128 and 126 Ma. This time is broadly similar to that time of gold mineralization of the Xiaoqinling, Xiong’ershan and Tongbai gold districts. These deposits were coeval with the early Cretaceous widespread gold mineralization. They should be the result of tectonism and Magmatism arised from lithosphere destruction in the eastern China.
