| 摘 要： | 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。

| Abstract: | The present paper has studied magnetic fabrics of Quaternary basalts in Chifeng area, Inner Mongolia and analysed magnetic anisotropic characteristics of such different structures of basalts as ropy flow structure, prismatic joints and vesicular structure. Based on an analysis of magnetic fabric characteristics like direction of maximum magnetic principal axis, it is known that basides being controlled by flow direction, magnetic fabrics are affected by such factors as terrestrial magnetic field and gravity field. |
