新巴尔虎右旗巴扬山火山断陷盆地铀-多金属成矿地质条件分析

摘要

Bayangale downfaulted volcanic basin locates in the same metallogenic area with Er Nuote ore-field of Mongolia in China - Russia - Mongolia uranium - polymetal metallogenic belt, and has the similar geological conditions with the Streltsovskoye uranium orefield in Russian. Through investigating the basement, cover rock, uranium content of rocks , structure and uranium-polymetal mineralization in the areas, the basin was believed to bear the geologic structual setting and fairly good condition for volcanic -type uranium - polymetall mineralization .%巴扬山火山断陷盆地位于中、俄、蒙铀-多金属成矿带上,与俄罗斯斯特列措夫铀矿田有着相似的成矿地质条件,与蒙古多尔诺特铀矿田处于同一成矿区.通过对基底、盖层、岩石铀含量、构造和铀-多金属矿化等方面的调查分析,认为该盆地具备了火山岩型铀-多金属成矿的地质构造环境,具有较好的成矿条件.
