Abstract: The mechanism of kink-bands, developed in experimentally ,and naturally deformed stibnite, could beexplained by studying them under the microscope ,and obtaining their X-ray pole figures. Naturally deformed stibniteis usually subjected annealing. Thus, twins, grains with low angle boundaries ,and elongated subgrains may be developed.When these features studied under microscope, some information is obtained about the deformation history of deformedstibnite.
