摘要
本文主要通过磁化率各向异性即磁性组构的研究,证明山东蒙阴金伯利岩矿床是属于侵入成因,并阐述了用磁性组构取代岩石学组构测量是地质学发展的一种新趋势。根据视极移曲线及同位素测定岩石年龄的方法,确定岩体的形成时代为加里东期岩浆活动,以此对燕山期岩浆活动的结论提出质疑。
On the basis of the stuoly of anisotropy of magnetic susceptibility (magnetic fabric) this paper proves that the origin of the kimberlite deposit belongs to the intrusive type and expound that it a newtendeney in geological development to replace the measurement of petrological fabric by magnetic fabric. According to the methods of apparent-pole moving Curve ancl isotopic age dating of roek, the intrusive mass was formed cluring Caledonian period instead of Yanshanian
