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.
