摘要

Based on mineral petrology, type of quartz recrystallization, quartz fractal dimension and finite strain analysis of Funiushan tectonic belt, the results showed that the characteristics of metamorphic-deformation in Funiushan tectonic belt changed in apparent regularity under the influence of Luonan-Luanchuan fault belt.  From tectonic zone to the north,t he pattern of recrystallization of quartz changes from the SR to the GBM, the ratio of axial gradually become smaller, the shape of strain ellipsoid changes from long cigar to flat ellipsoid, and the deformation of rocks gradually weakened. These features reflect that tectonic stress changes from small to lager, the temperature changes from low to high.
