摘要
根据物探重、磁资料经数据处理提取重力区域场和局部场,区域场反应了基底构造的隆起和凹陷,重力局部场是基础构造层和上复构造层的综合反应。磁测资料经数据处理提取表、中、深3层磁性结构的磁场,深层区域磁场的场源与重力基础构造层吻合,反应深部基岩,中层演变为五大岩体。
According to geophysical gravity and magnetic data from the data regional and local gravity field, the regional field revealed base upheaval and sag. Local gravity field was comprehensive response of the basic tectonic level and upper tectonic level. Magnetic data l^om the data-processing table, deep three-tier structure of the magnetic field and the plutonic magnetic field sou- rce were anastomosis of the gravitational base structural layer, revealing deep base rock, and mesozone evolved into five zones. Gravitational and magnetic structure is an important basis for the forecast of gold, silver and copper.
