| 摘 要： | 甘肃省西和县大坪测区、礼县马家沟测区、肃南县黑沟西测区应用高精度磁法测量划分弱磁性地层界线的效果良好,岩性磁化率差值在10～20×10-5SI以上,磁异常差值在10～20nT以上的弱磁性地层界线可以明显区分。在实际生产中对地质填图起到了指导作用。

| Abstract: | The effect of recognizing the stratigraphie boundary of weak magnetism in Daping area of Xihe County, Majiagou area of Lixian County and west Heigou area of Sunan County in Gansu Province by means of high-precision magnetic survey is good. It provided guide to geological mapping in practice. It can recognize the stratigraphic boundaries if the difference of magnetic susceptibility is more than 10-20×（10^-5SI） and the differ- ence of magnetic anomaly more than 10-20nT. |
