| 摘 要： | 为在甘肃北山西段覆盖区寻找隐伏铁矿,深入研究了古堡泉铁矿区的1:5万航磁资料,依据航磁圈定的异常结果,在重点地区进行1:5000地面磁法测量,划分出两个异常带,圈定出C1 ～ C8地磁异常,对这8个磁异常进行推断解释,再进行工程验证,最终发现了古堡泉铁矿床.分析航磁异常、地磁异常和矿体三者间的对应关系,认为外围还有一些航磁异常具有进一步工作的价值.

| Abstract: | In order to find concealed iron deposits in western Beishan of Gansu Province, the authors studied in detail 1 ： 50 000 aeromagnetic data of the Gubaoquan iron ore district, performed 1 ： 5 000 surface magnetic survey at the key area based on anomalies delineated by aeromagnetic survey, divided the anomalous area into two anomaly zones, delineated C1-C8 geomagnetic anomalies, and then made deduction, interpretation and engineering verification for these eight anomalies, which led to the discovery of the Gubaoquan iron deposit. Based on an analysis of the corresponding relationships between aeromagnetic anomalies, geomagnetic anomalies and ore bodies, the authors hold that there are still some aeromagnetic anomalies in the outskirt of the ore district which deserve further work. |
