提高航空磁测精度 扩大应用范围 增进地质效果

本文对广西柳州、华北平原和湖南雪峰山、江苏海州、甘肃白银厂等地以不同比例尺、不同灵敏度仪器所取得的航磁测量结果进行了对比分析,认为提高航磁测量精度（从低精度到中高精度）、加大比例尺后能够取得较为丰富、详尽的磁场信息,这对研究地质构造、提高普查找矿能力将起到重要的作用。

STRIVE TO RAISE PRECISION OF AEROMAGNETIC SURVEY,ENLARGE ITS APPLICATION AND IMPROVE ITS GEOLOGICAL EFFECT

Analysis and correlation have been made on aeromagnetic data at diverse scales obtained from such areas as Liuzhou of Guangxi, North China plain, Xuefengshan of Hunan, Haizhou of Jiangsu, and Baiyinchang of Gansu by means of instruments of different sensitivities. The results obtained lead the authors to believe that, by raising the precision of aeromagnetic survey (from low precision to moderate or high precision) and magnifying the surveying scale, relatively abundant and detailed information on magnetic f teld might be obtained, and this will surely play a substantial role in investigating geological structure and improving ore-prospecting abilities.
