摘　　要：在充分研究调查区已有资料的基础上,通过开展地面高精度磁法测量,初步查明调查区磁场分布特征,进行磁场分区,圈定局部磁异常,分析磁异常与地质构造及矿产的关系;结合已有的地质、化探及遥感资料,对磁异常进行优选,筛选出具找矿意义的异常,并对其前景作出评价。Based on the full study of the existing data in the survey area, through the ground high-precision magnetic survey, the magnetic field distribution characteristics of the survey area are preliminarily found out, the magnetic field is divided, the local magnetic anomaly is delineated, and the relationship between the magnetic anomaly and geological structure and minerals is analyzed;Combined with the existing geological, geochemical and remote sensing data, the magnetic anomaly is optimized, the anomaly with prospecting significance is screened, and its prospect is evaluated.
