摘要
Five mathematical models of the superposition of deformational magnetic fabric on sedimentary magnetic fabric are presented. These models are represented by various combinations of pure shear and simple shear. The diagrams of the variations in the main magnetic anisotropy parameters with strain can help in recognizing weak ductile deformation in sedimentary rocks. © 1990 Academia, Publishing House of the Czechoslovak Academy of Sciences.
