Deformation experiments of Carrara marble were conducted under increasing temperatures (temperatures 300℃ - 550℃, confining pressure 0. 5Mpa, strain - rate 5 × 10- 6 s-1 ). The experiments reveal that calcite rocks show different deformation behaviors and corresponding microstructural characteristics under different temperatures. By analyzing microstructural characteristics, preferred grain shape orientation variation of the primary rocks and deformed specimen, the deformation features of Carrara marble are summarized: twinning, fracturing dominates deformation of the rocks at temperatures between 300℃ and 450℃; dynamic recrystallization occurs in the temperature range of 450- 550℃; the brittle to crystalline plasticity transition deformation is observed at around 450℃, twinning and crystal - plastic deformation become dominant with further increasing temperature.
