摘　　要：针对近年来关于沽源-红山子铀成矿带内几个著名矿床的的研究进行了总结,并着重于该成矿带赋矿围岩与矿体年代学研究作了简要分析归纳,包括对成矿带内各矿床的铀矿矿体以及赋矿围岩年代学研究新进展进行了归纳总结,通过钻石SHRIMPU-Pb测年结果比较了赋矿围岩与矿体年代学差异,得出了相关规律:沽源-红山子铀成矿带内的赋矿围岩在时空格局上形成了“北东老、西南新”的分布规律;从形成时代可以看出,矿化年龄明显小于成岩年龄,暗示成矿与成岩作用间不存在直接的成因关系,二者可能仅为空间上的关系。这可为探讨沽源-红山子铀成矿带内铀矿床的成因和指导下一步铀矿勘查提供理论依据。This paper Mainly summarizes several famous deposits in the uranium mineralized belt of Guyuan-Hongshanzi in recent years,and focus on the chronology of the mineralized belt's supporting perigee and ore body.The chronology of the uranium ore bodies and the mineralization enclosure of the deposits in the mineralized belt is summarized,and the chronological differences between the mineralization enclosure and the mineralization body are compared through the diamond SHRIMPU-Pb dating results.According to related laws,it is found that the ore-bearing surrounding rocks in the Guyuan-Hongshanzi uranium metallogenic belt have formed a distribution pattern of"old in the north east and new in the southwest"in the temporal and spatial pattern.From the formation age,it can be seen that the age of mineralization is significantly smaller than the age of rock formation,implying that there is no direct causal relationship between mineralization and rock formation,and the two may only be spatially related.This provides a theoretical basis for exploring the genesis of uranium deposits in the Guoyuan-Hongshanzi uranium mineralization belt and guiding the next uranium exploration.
