本文阐述了重磁弱异常概念,提出了当代采集方式下重磁弱异常可信度的判断标准,并提出针对重磁弱异常的处理新技术,该技术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 expounds the concept of heavy and weak magnetic anomalies, puts forward the judgment criteria of the credibility of heavy and weak magnetic anomalies under the current acquisition mode, and proposes a new processing technology for the heavy and weak magnetic anomalies. This technique consists of the technology of eliminating interference and the technique of weak anomaly extraction Composition, the actual application of significant results. With the development of geology exploration to the fine direction, the heavy and medium-magnetic weak anomalies will receive more extensive attention.
