摘　　要：为加强重点成矿区带航空物探调查工作,中国地质调查局组织实施了重要矿产资源调查计划及应用项目,在新疆可可托海进行1∶5万航磁调查工作,获取了高质量的航空磁测数据45 992. 6 km测线;完成研究区及周边岩性、物性测量工作,获得该区域各类重要岩石磁性参数;形成了一套信息丰富、覆盖面积广的航磁系列图件,填补了研究区大部分地区航磁资料空白,为普查找矿和研究区域地质构造提供了新的基础资料。通过航磁筛选出重点异常进行地面查证,发现磁铁富矿1处、铜矿化蚀变带2条、重要找矿线索12处,获得良好的找矿效果。In order to strengthen the aero geophysical survey in the key metallogenic belts, China Geological Survey carried out an important mineral resources investigation plan and applied project. Based on the 1∶ 50 000 aeromagnetic survey in Keketuohai of Xinjiang, the authors obtained the high quality data （45 992.6 km survey line） of aeromagnetic survey. They finished the physical property measurements of rocks in the study area and its surroundings, and acquired the magnetic parameters of all kinds of important rocks. The aeromagnetic series maps with abundant information and wide coverage were completed, which filled the gaps of aeromagnetic data in most parts of the study area and provided the new basic data for prospecting and regional tectonic research. The authors made ground verification for the key anomalies selected by aeromagnetic, and found out one magnetite rich ore, two copper mineralization alteration zones and twelve important prospecting clues, indicating an excellent prospecting effect.
