Biomineralization of complex composite architectures comprising the shells of molluscs is known to proceed via self-assembly and in accordance with thermodynamic boundary conditions set by an organic macromolecular framework that is regulated by the organism. Hence, theoretically, the formation of these ultrastructures can be reproduced using the analytical backbone of various physical theories that are commonly employed to express crystal growth of man-made materials. Using a two-dimensional Monte Carlo Potts model simulation, we quantitatively describe and fully predict the structural evolution of the prismatic assembly in the shell of Pinctada nigra. The model, based on hierarchical motion of different types of grain boundaries that are involved in structural formation, has the capacity to describe the morphogenesis of various other biogenic and synthetic polycrystalline composite systems.

古典层次的颗粒边界运动完全描述了软体动物钙化棱柱形组织在软体动物中的形态发生。

已知包括软体动物壳的复杂复合结构的生物矿化是通过自组装并根据由有机物调节的有机大分子框架设定的热力学边界条件进行的。因此，从理论上讲，可以使用各种物理理论的分析骨架来再现这些超微结构的形成，这些理论通常用于表达人造材料的晶体生长。使用二维蒙特卡洛波特模型仿真，我们定量地描述和充分预测了黑壳Pinctada黑壳中棱柱形组件的结构演变。该模型基于参与结构形成的不同类型晶界的分层运动，具有描述各种其他生物成因和合成多晶复合系统形态的能力。
