| 摘 要： | 隐伏矿体的空间定位预测研究，已成为当今成矿预测和找矿勘探实践的当务之急。甚低频电磁法（ＶＬＦ－ＥＭ），具有仪器轻便，方法简单、经济高效等优点；实践表明，应用甚低频磁倾作测量及倾角资料的Ｆｒａｓｅｒ滤波、线性滤波处理成果，可以有效地揭示隐伏区段矿体走向延伸与矿化富集部位，矿体形态，产状、埋深特征及以及矿体的空间展布、递变规律、为隐伏矿体预测提供科学依据。

| Abstract: | The location forecasting of buried ore has become a task of top priority for ore estimate and exploration.VLF EM is one method with a lot of superiorities,such as partability and high efficiency,etc.Combined with studies of Fraser filtering and linear filtering,the VLF EM can be seccessfully applied to determine the location,the shape,the occurrence and the depth of buried orebodies.Also,it can reveal the changing laws of metallization and work as a guideline for the buried ore exploration. |

| Keywords: | very low frequency electromagnetic magnetic angle of VLF Fraser filtering linear filtering location forecasting of ore |
