摘　　要：阐述了重磁弱异常的概念,提出了当代采集方式下重磁弱异常可信度的判断标准,并研究出重磁弱异常处理新技术。该方法由消除干扰处理技术和弱异常提取技术组成,实际应用效果显著。随着地质勘探向精细方向发展,重磁弱异常将得到更加广泛的关注。This paper introduces the concept of weak gravity and magnetic anomaly,and presents criterion and method for identifying truthfulness of weak G&M anomalies.The method for processing of G&M weak anomaly data was also put forward.The proposed method consists of noise elimination and weak anomaly extraction.With the improvement of data quality,research and application of weak G&M anomaly will attract more and more attention.
