Abstract:Although the Qingchengzi and Wulong ore concentration areas in the eastern Liaoning Province are characterized by a similar tectonic background, their mineralization ages, orehosting rocks and orecontrolling structures are very different. Previous researches and our new data on tectonic background, orehosting rocks, magmatism ages and occurrences, orecontrolling structures, mineralization ages and erosion depth of the gold and PbZnAg polymetallic deposits in the Qingchengzi ore concentration area and the Wulong and Sidaogou gold deposits in the Wulong ore concentration area suggest that the differences between mineralization in these two ore concentration areas are most likely related to differential uplift and erosion from the late Triassic period.Therefore, we propose a “threefloor metallogenic model” for the goldpolymetallic deposits in the eastern Liaoning Province. In this metallogenic model, the early Cretaceous “Wulong type” goldbearing quartz vein deposit within the middle Jurassic deformed granitic pluton is located in the lower part, and the early Cretaceous “Sidaogou type” structural alteration type and quartz vein type gold deposit within the Paleoproterozoic metaclastic sedimentary rocks from the lower Liaohe Group is located in the middle part. The upper part of the metallogenic model is the “Baiyun type” quartz veinbearing and structural alteration type gold or PbZnAg polymetallic deposit near the contacts between the Paleoproterozoic metaclastic rocks of the Gaixian Formation and marbles of the Dashiqiao Formation of the upper Liaohe Group.These goldpolymetallic deposits were mainly formed in the Triassic period with middle Jurassic and early Cretaceous mineralization overprints. It is most likely that some “Wulong type” and “Sidaogou type” ore deposits exist beneath the currently explored ore bodies in the Qingchengzi ore concentration area, and some “Wulong type” goldbearing quartz vein deposits may exist beneath the currently explored ore bodies in the Sidaogou gold deposit. The Qingchengzi ore concentration area with relatively weak erosion from late Triassic period is therefore characterized by favorable deep metallogenic conditions and more attention should be paid for deep metallogenic explorations in this area in the future.
