摘要
给出了位场场源边界识别的最新技术,利用斜导数法、斜导数水平梯度法及theta图法对山西境内古裂陷带和古拼接带及山西地堑系主要断裂构造进行了边界位置识别研究,并与常规水平梯度法进行对比分析。对理论模型和山西实际资料的边界识别结果表明:这些新技术的识别效果都优于传统水平梯度法,能获得更丰富的地质信息。
This paper presents and compares some new techniques for source boundaries detection using potential - field data. The geologic boundaries of paleo - fault zone and faults in Shanki Province with better resolution are recognized by the following methods： tilt derivative （TDR）, total horizontal gradient of the TDR and theta map, etc.. The results indicated that the new detection technology is more effective and accurate than the traditional horizontal gradient one and can gather more geological information.
