摘　　要：通过胶东某金矿普查区大比例尺高精度磁法测量和重点区段初步工程验证 ,取得如下认识 :①划出了不同岩性空间分布范围 ;②编制了剪切带变形构造系统地质图 ,实测和推测出剪切带构造2 0余条 ;③建立了“主剪切带型”和“次级剪切带型”金矿地质—地球物理找矿模型 ,提出了 4片找金有利区 ;④经工程验证 ,在所钻探的 8个钻孔中 ,有 6个钻孔发现了工业品位的金矿体。实践表明 ,在本区开展地面高精度磁测具可行性和有效性。The application of ground high-precision magnetic measurement to the reconnaissance of one gold mine in eastern Shandong is briefed. After the large scale ground high-precision magnetic measurement and preliminary engineering testing,more than 20 shear structures were identified, 4 prospects for gold prospecting were outlined, and ore bodies over pay grade were met in 6 out of 8 drill holes. The ground high-precision magnetic measurement is an effective and feasible means for exploration.
