Аннотация

This paper presents a possible mechanism forming crystals with antiskeletal morphology due to their regeneration after partial dissolution. Consideration is carried out by numerical 2D-simulation of the coordinate zone evolution of a single crystal ball using the kinematic model of regeneration crystal surface growth. According to this model, the genetic predecessors of subindividuals on the regenerated crystal are protrusions formed on its surface during the partial dissolution stage. It has been shown that the main parameter responsible for the antiskeletal morphology of regenerated crystals is the ratio of depression depths (l) between adjacent protrusions and protrusion radii (r), 0 < l/r < 1. When l/r ≤ 0.1, the stationary shape of the regenerating ball is a polyhedron. If l/r > 0.6, there is a ball with a rough surface covered by flat areas on the most slowly growing faces. The crystal with the antiskeletal morphology grows at intermediate values of l/r.
