摘要
玄武岩样品取自吉林省舒兰县古舒镇大石顶子山，其岩浆活动受佳－伊地堑控制。本文对玄武岩磁组构和钛磁铁矿矿相学以及玄武岩柱状节理产状等方面作了综合分析，并统计了地堑基底花岗岩磁组构特征，借助于地堑内部地层产状参数，确定了吉舒玄武岩浆顺层侵位的岩床模式。
The basalt samples are collected from an isolated Peak which is located in the JiamusiYitong Graben,near Jishu village,northeast Jilin Province.After the multidisciplinary analysis of magnetic fabric and mineragraphic and the attitude of the basalt columnar joint,and the magetic fabric data of the adjoining granite rock as well as the attitude of the sedimentary rock in the graben,the paper give a geodynamics modelof the emplacement of the basalt.
