Complex Orogeny and superimposed transformation together lead to complex tectono-magmatic activities and complex metallogenic systems in Tethys, Tam Giang. Wenquan fault is the main rock-guiding and ore-guiding structure in the study area. The metallogenic system is dominated by porphyry-sicarn type Cu-Fe-Pb-Zn and Yunbolite type Sn-w deposits, the mineralization is closely related to the post-acidic Magmatic hydrothermal system triggered by the closure of the middle Tethys Ocean in the late Yan Mountains and the subduction of the new Tethys Ocean, and formed in the post-collision intracontinental extensional tectonic environment. It is considered that the magmatic hydrothermal Sn-W-Be metallogenic system in the Wenquan fault-magmatic Belt and the sicarn/magmatic hydrothermal Fe-Pb-Zn-Ag-Hg polymetallic metallogenic system belong to the same tectono-magmatic thermal events at different levels and in different surrounding rock environments, it is the product of composite mineralization. The metallogenic model of Wenquan fault structure-magmatic belt is constructed through the study of composite metallogenic series. It is considered that further exploration of Late Yanshan-Himalayan granitoids is the key link of subsequent ore prospecting, and Pb, Zn, Sn, W, Be polymetallicmetallogenic series related to acid rocks is the key ore prospecting direction in the area. The study shows that the beryllium mineralization of the Shi-guanghe tin-tungsten-beryllium deposit is spatially attached to the Hercynian altered Gabbro di-abase vein (307.9 ± 3.2 Ma), but the ore-forming ages are concentrated at 68~56 Ma, which is closely related to the post-acid Magmatic Hydrothermal System of the late Yan Mountains, it is suggested that the outer Yanfang area north of Shikong river is the preferred target for beryllium mineral resources, and the Songpo, Guangshan and Zhonghe areas on the east side of the hot spring fault, the deep part of Hetaoping area on the south-west side of Wenquan Fault have the prospect of searching for tungsten-beryllium ore related to late acid rock body. <摘要译文>
