摘要
立德堂地区位于松辽盆地西南部,是盆地内重要的产铀区域。为查明立德堂地区放射性元素的分布特征及铀成矿潜力,通过对区内地面伽马能谱数据统计分析,提取了研究区地面伽马能谱古铀含量、古铀迁移量、相对变迁系数等参数,分析了地面伽马能谱铀元素分布特征及迁移富集规律。对比区内已发现的铀矿床及矿带呈现的地面伽马能谱特征,圈定了洋井、青龙山、四合屯-辽河镇、西蒙古屯-腰伯吐、西乌兰花-东乃木格勒、西腰茫哈、哈门艾勒-中敖本台等7个铀成矿远景区,为下一步找矿工作的部署指明了方向。
Located in the southwest of Songliao Basin,Lidetang is an important uranium producing area in the basin.In order to find out the distribution characteristics of radioactive elements and uranium metallogenic potential in lidetang area,the characteristic parameters of‘paleo-uranium’,‘activated uranium’,‘relative migration coefficient’were extracted from the statistic and analytical result of gamma-ray spectrometry data,and used to study the distribution,migration pattern of uranium concentration.By referring to the ground gamma spectrum characteristics of uranium deposits and orebelts discovered in the study area,7 prospecting sectors hare been delineated,they are Yangjing,Qinglongshan,Sihetun-Liaohezhen,Ximenggutun-Yaobotu,Xiwulanhua-Dongnaimugele,Xiyaomangha,Hamenaile-Zhongaobentai.
