摘要
巴升河位于大兴安岭铀成矿带柴河盆地,以往铀矿找矿研究工作程度极低。通过对区域典型铀矿点航空伽马能谱特征分析,建立了区域火山岩型铀矿化区航空伽马能谱异常标志:航放铀高场、铀增量(ΔU)高值晕、活性铀(Hu)低值晕、航放F参数高值晕。据此,对研究区航空伽马能谱数据进行了处理,对异常特征进行了分析,圈定了5片航放综合异常晕;结合地层、构造、物化探条件,对圈定的5片航放综合异常晕铀成矿潜力进行了研究,发现研究区H01、H02、H03航放综合异常晕具有较好的火山岩型铀成矿潜力。
Bashenghe is located in Chaihe Basin,Da Hinggan Mountains uranium metallogenic belt.Previous research on uranium prospecting has been very insufficient.Based on an analysis of the characteristics of airborne gamma-ray spectroscopy of typical regional uranium deposits,the authors established the anomalous indicators of airborne gamma-ray spectroscopy in regional volcanic-type uranium mineralization areas:high-value field of uranium,high-value halo of uranium increment(Delta U),low-value halo of active uranium(Hu),and high-value halo of airborne F-parameter.In terms of these features,the airborne gamma-ray spectrum data of the study area were processed effectively,then anomalous characteristics were analyzed,and five airborne comprehensive anomalous halos were delineated.Combined with stratigraphic,structural and geophysical and geochemical conditions,the uranium metallogenic potential of the five airborne comprehensive anomalous halos was studied.Finally,the integrated anomalous halos formed by H01,H02 and H03 in the study area was found with good volcanic uranium metallogenic potential.
