摘　　要：通过对个旧斧石晶体的微形貌、化学成分及生成条件的研究认为,个旧产出的斧石种类属于铁斧石,它是在fo_2=10^(-21)—10^(-31),中偏高温溶液中生成的.应用晶体人工生成的研完成果表明:斧石晶体表面台阶是溶液中的溶质通过体扩散形成的;而不同密度台阶的叠置则反映了晶体生长过程中的动力学参数的变化.This paper deals with the surface micromorphology and chcmical composition, together with formatiom condition of axinite. Chemical analysis illustrated that it belongs to ferroaxinite and its formatiom is under the condition of medium-high temperature at fo_2= 10^(21)-10^(31). The study of synthetic crystal growth demonstrates that the steps on the surface of axinite crystal are the reuolts of volume diffusion in the solution. Meanwhile replacement and overlap among steps of diffferent density may due to variety of dynamie parameters in the process of crystal growth.
