| 摘 要： | 为了解内蒙古中部的锡林浩特、巴林左旗等地区岩矿石磁性特征,更好地对该地区的航磁异常进行综合解释,使用航遥中心研制的ZH-1磁化率仪,于2009~2011年间先后四次在该地区进行了野外岩矿石磁化率实测。并在统计、分析实测磁化率数据的基础上,研究了该地区岩矿石磁化率分布情况,分别叙述了区内沉积岩、侵入岩、火山岩、变质岩、矿石及围岩等各种类型岩矿石的磁化率特征,对岩矿石磁化率与航磁、矿产间的联系进行探讨,为磁法勘查解释、地质找矿提供了重要依据。

| Abstract: | In order to understand the magnetic features of rocks and ores in the region of Xilin Hot and Bairin Left Banner of inner Mon-golia, the authors made integrated interpretation of the aeromagnetic anomalies in this area by using ZH-1susceptibility meter designed and developed by China Aero Geophysical Survey and Remote-Sensing Center for Land and Resources. The magnetic susceptibilities of rocks and ores were measured four times in central Inner Mongolia during 2009 to 2011. Based on the statistics and analysis of the actu-al measured data of magnetic susceptibilities, the authors studied the distribution of magnetic susceptibilities of rocks and ores in this area, and described the magnetic susceptibility features of sedimentary rocks, intrusive rocks, volcanic rocks, metamorphic rocks, ores and wall rocks, and dealt with the relationship between magnetic susceptibilities and aeromagnetic anomalies as well as the relationship between magnetic susceptibilities and ferromagnetic minerals. The results obtained are important for interpretation of magnetic explora-tion and geological prospecting. |
