The Bieluwutu Cu-Pb-Zn deposit is located in the Ondor Sum region of the western Xing’an-Mongolia orogenic belt, North China. The host rocks of the deposit consist of metasandstone, tuffaceous slate, andesitic tuff and fragmented felsic volcanic rocks, which have previously been regarded as the Early Carboniferous Amushan Group. Zircon U-Pb ages for two tuffaceous units are 435 ± 2 Ma and 430 ± 2 Ma, showing that volcanism occurred in the Early Silurian. The tuffaceous rocks are enriched in large ion lithophile elements (LILE; e.g., Rb, Ba, K) and light REE, and depleted in high field strength elements (HFSE; e.g., Nb, Ta and Ti) with depleted isotopic components (ε_Nd(t) = 0.14–0.84), indicating that they were derived from partial melting of lower continental crust with the involvement of mafic magma.

Bieluwutu is intended to be a Kuroko-type VHMS deposit formed in an interarc rift basin in the Early Silurian. Three types of ores have been identified at Bieluwutu, including massive Pb-Zn, brecciated Cu-Zn and disseminated Cu ores. Results of sulfide laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses indicate that Se and Sn are enriched in chalcopyrite from the disseminated and brecciated ores with high Se/Te ratios. Tellurium, Co, Pb and Bi are enriched in chalcopyrite, sphalerite and pyrite from the brecciated ores, whereas Mn, Ni and Tl concentrations are higher in pyrite from the massive ores. These differences suggest a decreasing temperature and increasing f(O₂) trend from the disseminated to brecciated and massive ores. High contents of Mn, Tl, Ni in massive ores are typical for metals derived from surrounding felsic volcanic rocks. Strong enrichment of trace elements, such as Bi, Te, Se and Sn, is consistent with a magmatic contribution to the ore-forming fluids. The underlying subvolcanic intrusion not only served as a heat engine but also supplied volatiles and metals.

别路屋图铜-铅-锌矿床位于华北兴安-蒙古造山带西部的Ondor Sum地区。该矿床的主岩由元砂岩，凝灰岩板岩，安山岩凝灰岩和破碎的长英质火山岩组成，以前被认为是早期石炭纪的阿木山群。两个凝灰质单位的锆石U-Pb年龄为435±2 Ma和430±2 Ma，表明火山活动发生在志留纪早期。凝灰岩富含大型的离子亲石元素（LILE；例如，Rb，Ba，K）和轻稀土元素，并且贫化了高磁场强度元素（HFSE；例如，Nb，Ta和Ti），其中同位素元素已耗尽（_εNd（t）= 0.14-0.84），表明它们是由镁铁质岩浆参与下陆壳的部分熔融而得。

Bieluwutu计划是志留纪早期的一个弧间裂谷盆地中形成的Kuroko型VHMS矿床。在别路屋图，已经鉴定出三种类型的矿石，包括块状铅锌矿，角砾状铜锌矿和弥散型铜矿。硫化物激光烧蚀电感耦合等离子体质谱（LA-ICP-MS）分析的结果表明，Se和Te含量高的弥散和角砾状矿石中的黄铜矿中富集了Se和Sn。碲，钴，铅和铋的含量丰富于角铁矿中的黄铜矿，闪锌矿和黄铁矿，而块状矿石中的黄铁矿中锰，镍和三价铁的含量较高。这些差异表明温度降低而f（O ₂）从散布到角砾状和块状矿石的趋势。块状矿石中高含量的Mn，Tl，Ni是典型的来自周围长石质火山岩的金属。诸如Bi，Te，Se和Sn等微量元素的富集与岩浆对成矿流体的贡献相一致。潜在的火山下侵入不仅充当了热机，而且还提供了挥发物和金属。
