大板金矿位于华北地台北缘 ,山海关—北镇隆起北段，空间上分布于排山楼金矿北东端。应用高精度磁测结果对大板金矿区的基底构造、断裂构造格架进行分析，追索和圈定含金糜棱岩带，结果表明，从构造格架上看大板金矿与排山楼金矿既有可比性，又具其独特性；高磁推断的近东西向糜棱岩带为本区金成矿有利地段。大板金矿高精度磁测找矿实践证明，在提高信息密度的前提下，利用高磁对金矿直接进行圈定是可行的。
Daban gold deposit is located in the northern margin of North China platform, Shanhaiguan - Beizhen uplift north section, located in the spatial distribution of the northern end of Paishanlou gold mine. The application of high-precision magnetic measurement results to the analysis of the basement structure and fault tectonic framework of Dapan gold mining area and the recovery and delineation of gold mylonite belt show that from the tectonic framework, The ore is both comparable and unique. The near-west-to-west mylonite belt inferred by high magnetic field is the favorable gold-forming area in this area. Dagang gold mine high-precision magnetite prospecting proved that in the premise of improving the information density, the use of high magnetic direct delineation of gold is feasible.
