应用航磁资料研究金伯利岩预测区

A STUDY ON THE PREDICTION OF THE TARGET AREA OF KIMBERLITES BY AIRBORNE MAGNETIC DATA

摘要:

本文针对目前应用航磁资料进行金伯利岩预测的有效性,重点叙述了区内各类岩矿石磁性特征,并说明了金伯利岩具有一定磁性,应用磁测资料可以进行预测。分析研究了区域磁场特征与地层岩性、断裂构造的关系,对蒙山负磁场作了分析探讨。并根据已知金伯利岩带在航磁图上反映的特征,通过对全区磁场的分析研究,提出了六个金伯利岩预测区。

Abstract:

On view of the effectiveness of predicting the kimberlite presence by aid of airborne magnetic data, the author focuses on the magnetic properties of various rocks and ores, and demonstrates that kirnberlite is somewhat magnetic and can be targeted by the data from magnetic survey. The relationship between the features of the regiortal magnetic felds on the one hand and the lithologic characters of the strata and fractures on the other is investigated and analysed; meanwhile, the negative magnetic fields of...
