Abstract

On the base of autoradiography method including digital treatment it was investigated the impurity distribution in natural diamonds.lt was established the alternation of zonal and fibruilar distribution of several impurities. This phenomenon treatment may be realized on the base of combaing of Cahn-Routburd-Shklowskii [5-7] growth theory with PrigogineTike synergetic idea. According to [5-7] the type of crystallization mechanisms depends on relation between crystallization moviting force and value of combaine parameter, depending of boundary wide. A lot of regimes of crystallization including the alternation of normal and tangential mechanisms are discussed.
