We proposed a set of tabulate shim coils to improve the imaging field homogeneity for permanent magnet. By studying the magnetic spherical harmonics and its Taylor expansion, the proposal of designing lower-order radial coils was derived including x, y, xz, xz~2, x~2-y~2 etc. In addition, a novel composite design was presented for the axial coils. By controlling the shim currents of axial coils, different axial magnetic fields can be obtained. This method simplified the design process of axial coils, and made the axial correcting magnetic field more precise.

The tectonic rocks along the fault zone are composed of cataclastic rocks and mylonites formed in higher, middle and lower temperature. Respectively, both of structural features and rocks have the features of multiple phase's of deformation. The deformation features of main minerals in the high temperature mylonites show that: the quartz has the form of long single crystal and the fabric feature of point maximum near X axis; the feldspar has the form of recrystallization assemblage, They present a high amphibolite-granulite facies with temperature ＞600℃ and depth ＞20km. The deformation features of mylonites formed in middle temperature show that: the quartz has the form of polycrystal banding and the fabric feature of point maximum near Y axis and small circle girdle with Y rotational axis; the feldspar has the form of a coremantle structure, They reflect a high greenschist-lower amphibolite facies with temperature from 400℃ to 600℃ and depth from 15km to 20km.
