| 中文摘要:谢米斯台成矿带是中国新疆北部重要的铀多金属成矿带，铀矿勘查突破令人期待。文章通过对典型铀矿床观察研究，建立了火山岩型铀成矿预测模型，在GIS平台系统提取了赋矿地层、含矿围岩、控矿构造、航磁推断隐伏岩体及断裂构造、U-Be元素组合异常、铀矿床和矿化点等各类成矿、找矿信息，采用MRAS系统中的特征分析模块进行铀矿产定位预测。按照后验概率大小划分了三级有利成矿远景区，其中A级包括赛力克、白杨河和七一工区3个远景区，显示出较大的铀成矿找矿潜力，在今后的找矿勘查中应给予充分重视。 |

| Abstract:The Xiemisitai metallogenic belt is an important uranium and polymetallic ore belt in northern Xinjiang, and the discovery of new uranium deposits is hopefully expected. In this study, the prediction model of volcanic type uranium deposits was constructed through the observation and study of typical uranium deposits. All kinds of favorable metallogenic and exploration information, including the hosted strata, country rocks, mineralization-controlling structures, buried intrusions and faults inferred by aeromagnetic data, U-Be element anomalies, uranium deposits and ore spots, was extracted by GIS. The Eigen-analyzing model in MRAS was used to predict and locate the potential uranium ore spots. The uranium metallogenic prospective areas were assigned to three levels according to the values of posterior probabilities which show great exploration potentiality of the Xiemisitai metallogenic belt. The authors hold that much attention should be paid to three A-level prospective areas, i.e., Sailike, Baiyanghe and Qiyi area, in future uranium exploration. |
