Fluid-influenced deformation and recrystallization of dolomite at low temperatures along a natural fault zone, Mountain City window, Tennessee Academic Article uri icon

abstract

  • Deformation of dolomite along a minor thrust fault within the Mountain City window, Tennessee, took place by twinning, fracturing, pressure solution, and recrystallization processes. Deformation otherwise unobservable can be seen using cathodoluminescence and doubly polished ultrathin sections. The regional geology suggests that deformation took place at a depth of 9km. Experimental data suggests that dolomite would not deform by dynamic recrystallization under these conditions. However, fluids may reduce the strength and increase the ductility of calcite rocks. Similarly, fluids may have reduced the temperature at which dynamic recrystallization could take place in these dolomitic rocks. -from Authors
