| 摘 要： | 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。

| Abstract: | Daban gold deposits are located on the north edge of North China Platform,on the north section of SanhaiguanBeizhen Uplift,and to the northeast of Paishanlou gold deposits.By high precision magnetic measurement,the basement structures and fault structural framework are analysed,and then two groups of goldbearing mylonite belts :NE-and EWtrending, are outlined,where on the joint position are Daban gold deposits.In addition,another EWtrending gold mineralized belt is newly inferred,which need further verified in the future. As a result,near EWtrending mylonite belts are favorable to gold mineralization in the studied area. |
