摘　　要：吐拉苏火山岩盆地所处大地构造位置属于博罗科努晚古生代岛弧带西段,该区域属于浅成低温热液型、斑岩型金多金属成矿重点区域,已发现多处金矿床(点)。以成矿预测理论和方法技术为指导,在系统收集和整理地质、物化探资料基础上,对研究区航磁、航放特征进行了综合分析,结合航磁异常查证结果,总结了找矿标志,建立了研究区金矿床物理-数学模型,优选出1处成矿远景区并进行了评价,为下一步开展金找矿工作提供了有利线索。The geotectonic position of Tulasu volcanic rock basin belongs to the west segment of the Boluokenu late Paleozoic island arc belt.The area is important in hypabyssal low temperature hydrothermal type porphyry gold polymetallic mineralization,where there are many gold deposits(ore sites)discovered.Guided by the theory and method of metallogenic prediction,the study systematically collects and collates the regional geological and geophysical data and comprehensively analyzes aeromagnetic and airborne radioactive characteristics in the study area.Based on the results of aeromagnetic anomalies verification,the prospecting markers were summarized,a physical-mathematical model of the gold deposit in the study area was established,and 1 mineralization prospect area was selected and evaluated,providing a favorable clue for the next-step gold prospecting work in the area.
