摘　　要：对内蒙古根河市得耳布尔等4幅1∶5万高精度磁测勘查资料的断裂构造和岩性进行了划分,并对推断的断裂构造和圈定的各种岩性进行了分析解释,指出了断裂构造、岩浆岩、蚀变岩与铜、铅、锌、钼、钨等多金属矿产的重要关系。同时说明该高精度磁测资料用于圈定断裂构造、隐伏岩体、蚀变岩效果较好。According to four pieces of 1 ： 50 000 high precision magnetic survey data which includes Derbur County of Genhe City of In-ner Mongolia Autonomous Regions, the fracture structure and lithology were classified in detail ,the deduced fault structure and the de-lineating lithology were analyzed and explained, the important relationship between tectonic, magmatic rocks, alteration rock with cop- per, lead, zinc, molybdenum, tungsten and other metals were also pointed out. At the same time, it was proposed that the effects are good for the delineation of faults, concealed rock, altered rock by using four pieces of high-precision magnetic data.
