| 摘 要： | 概述了国内外深部找矿的研究成果,指出深部找矿是当今发展的趋势。国内外重大矿产的成功发掘,其深度均在千米以上,铀矿化垂向分布深度可达4 km以上。综合介绍了国内外勘查深大矿床的特点和条件,认为岩石-构造条件是深部矿化定位的重要因素,复式岩体、成矿系统的垂向变化、构造地球物理-地球化学异常模型是深部找矿的关键依据。综述了中国南方湘南—桂北地区深部找铀的有利地质构造条件和潜力,成矿流体是该区铀矿化的根源,白垩—第三纪重大地质事件是该区深部铀成矿的重要前提,重大地质事件引发的NE-NNE,NW向深大断裂及断陷盆地是铀矿化赋存的重要场所和勘查靶区。在已知铀矿田、成矿带勘查范围基础上,在该区进行深部探索将会获得重大突破。探讨了湘南—桂北地区深部找铀的勘查思路和方法。

| Abstract: | This paper summarize research of deep ore prospecting at home and overseas,which is more and more important.These days,mining of the deep have achieved more than 1 km,and uranium mineralization locate 4 km deep in underground.Based on the characteristic and condition of deep deposits at home and overseas,authou concludes that metallogeny in the deep shows a very close relationship to rock-structure,complex rock body,ore-forming system variety in the vertical,and tectonogeophysics-geochemical anomaly.Finally,this paper mainly discusses uranium ore-forming conditions in southern Hunan and northern Guangxi,and concludes that ore-forming fluid at Cretaceous period-Tertiary period provide uranium source,which rich in NE-NNE and NW deep fault and fault basin.Based on known uranium ore felids and metallogenic belts,there are enormous achievement in deep ore prospecting. |
