| 摘 要： | 本文简要评述了Ishihara(1977)关于花岗岩类磁铁矿系列和钛铁矿系列的分类方案.对吉黑褶皱系南段(吉林省延边地区、黑龙江省牡丹江地区)花岗岩磁参数分布规律,磁性矿物类型以及磁异常进行了综合研究,笔者认为,该区花岗岩确有不同的磁性类型,并和它们磁性矿物的组合类型相对应.Ishihara的方案使得利用磁法能够很好地划分花岗岩岩石类型,因而具有广泛的实用价值.最后,通过实例讨论了例外情况的消除和解释方法.

| Abstract: | This paper gives a brief comment on the classification which divided the granitoids into magnetite-series and ilmenite series by Tshihara(1977). On the basis of studing magnetic susceptibility, magnetic minerals and magnetic anomalies in the south Jihei Fold belt, northeastern China. It is suggested that Ishihara's Scheme can be applicated to distinguish the different granitoids in this area. Some exceptions were eliminated or interpreted by statistical mothed. |
