本文对内蒙古赤峰地区第三纪玄武岩的磁组构进行了研究 ,分析了流动绳状构造、柱状节理、气孔构造等不同构造的玄武岩的磁各向异性特征。通过分析磁最大主轴方向等磁组构特征 ,认识到磁组构除受流动方向的控制外 ,还受地磁场及重力场等因素的影响 This paper studies the magnetic fabric of Tertiary basalts in Chifeng area, Inner Mongolia, and analyzes the magnetic anisotropy characteristics of basalts with different structures such as flow-like structures, columnar joints and stomatal structures. By analyzing the magnetic fabric features such as the direction of the largest principal axis of the magnet, it is recognized that the magnetic fabric is affected by factors such as the geomagnetic field and the gravitational field, besides being controlled by the flow direction.
