内蒙古乌拉特中旗小佑山东多金属矿位于华北板块北缘中段的狼山—渣尔泰山裂陷槽内，其产出的多处大型-超大型铜、铅、锌、铁多金属硫化物矿床特征具有相似性。通过对该多金属区域地质背景、矿区地质特征、矿化富集特点进行分析，结果表明：①区内矿床属于岩浆分异型矿床，区内中元古界渣尔泰山群石英岩组、板岩组为主要的赋存矿体地层，近 EW 向断裂与层间裂隙是矿化的有利部位；②矿床中的矿脉均受 EW—NNE 向断裂控制，成群成带密集分布，为不同时期、不同地点形成的多金属矿床；③蚀变破碎带内的硫化物多金属矿物组合地段是寻找矿化富集的主要地段，区内岩石中微量元素钒，钙，镍，钴，钛含量较高，且多期岩浆热液活动较强，具有较好的成矿远景。上述结论对于区内找矿工作有一定的参考价值。
內矇古烏拉特中旂小祐山東多金屬礦位于華北闆塊北緣中段的狼山—渣爾泰山裂陷槽內，其產齣的多處大型-超大型銅、鉛、鋅、鐵多金屬硫化物礦床特徵具有相似性。通過對該多金屬區域地質揹景、礦區地質特徵、礦化富集特點進行分析，結果錶明：①區內礦床屬于巖漿分異型礦床，區內中元古界渣爾泰山群石英巖組、闆巖組為主要的賦存礦體地層，近 EW 嚮斷裂與層間裂隙是礦化的有利部位；②礦床中的礦脈均受 EW—NNE 嚮斷裂控製，成群成帶密集分佈，為不同時期、不同地點形成的多金屬礦床；③蝕變破碎帶內的硫化物多金屬礦物組閤地段是尋找礦化富集的主要地段，區內巖石中微量元素釩，鈣，鎳，鈷，鈦含量較高，且多期巖漿熱液活動較彊，具有較好的成礦遠景。上述結論對于區內找礦工作有一定的參攷價值。

Xiaoyoushandong polymetallic mine in Urad Zhongqi,Inner Mongolia is located in Lang-shan-Zha'ertaishan rift through within middle section of the northern edge of north China platform,where many large scale-super large scale Cu,Pb,Zn Fe polymetallic sulfide deposits are characterized by similar features.Through analysis of the regional geological setting,mining geological characteristics,the charac-teristics of mineralization enrichment of Xiaoyoushandong polymetallic mine,the results show that:①the deposits in the mining area is belongs to magmatic differentiation type deposits,in the mining area,the Mesoproterozoic Erathem Zhaertai group quartz rock group,slate group are the main strata occurrence of orebody,the EW trending faults and inter-layer fissure is a powerful part of mineralization;②the ore veins in this ore deposits are all controlled by EW—NEE trending faults and distribute in groups and zones densely,the deposits are formed in different locations and times;③sulfide and polymetallic mineral as-semblage area is the main area for mineralization enrichment,contents of trace elements such as Vanadi-um,Calcium,Nickel,Cobalt,Titanium in the rocks of the mining area is higher than other areas,and the multi-period magmatic hydrothermal activity is strong,so,the metallogenic prospect of the mining area is good.The above conclusions have certain reference value for the the prospecting work in this area.
