| 摘 要： | 作者首先阐述了典型地区斜长石和石榴石矿物中的振荡环带特征;尔后,根据固溶体矿物结晶生长过程中的非平衡非线性特征,熔体聚合模型和正规溶液模型,提出了固溶体矿物中振荡环带成因的动力学模型。通过建立界面状态(组成)的质量守恒方程,合理地阐明了固溶体矿物中振荡环带的可能机理——非平衡自组织,寻找界面反应三重态是研究固溶体矿物中振荡环带的一条相当普遍的途径。

| Abstract: | The authors firstly expound the features of the Oscillatory zones in plagioclase and garnet in the several typical district; Secondly, based on the non-equilibrium and nonlinear features in the process of mineral crystal growth and the melt polymerization and regular solution models, We have proposed interfacc layer reaction-diffusion dynamic model forthe oscillatory zones. This model combined with mass-balance equation of mineral surface components, provides a possi-ble answer to the genesis of the oscillatory zones. Furthermore, this model can also be used to explain the genesis of theoscillatory zones of Solid-solution minerals, i. e., non-equilibrium self-organizationz. |
