Abstract: The Gaoliangdian Fe-Cu deposit is a volcanic-sedimentary metamorphic transformation of a copper-rich magnetite deposit in the Xinyang area of Henan Province, China, and lies in the northeast of the Tongbai orogenic belt. The main feature is a stratabound ore body in a lenticular skarn in the Er’langping rock group. The host-rock is amphibolite schist in the Dalishu Formation. The ore minerals are primarily magnetite and chalcopyrite. Skarnization and silicification are the most important type of alteration near the mine. Based on the geologic features, geophysical and drilling information, the authors discuss potential prospecting of the deposit. We believe that the southeast side of the ore bodies discovered in the Louziwan area has great potential for further prospecting. Meanwhile, the many well-mineralized outcrops in the Hejiawan area are also recommended for further exploration work.
