Experimental and quantitatively descriptive study of metamorphic textur

在微观到中尺度上对岩石结构的定量评价一直在进行中。这项研究认识到定量分析这种结构的重要性，以了解固体地球的动力学。个别研究的结果是独立的，分别描述如下：1）在火成岩中观察到的中尺度成层具有类似于Liesegang环的间距规律，其中沉淀物质的扩散控制了这一过程。这一发现为解释这种层状结构的形成提供了强有力的限制。2）两个相互竞争的学派试图解释石榴石雪球结构的起源。这项研究揭示了结构采用新技术结合常规相岩石学。获得了一些新的特征，他们评估的有效性的两个学校作为一个起源的结构。3）这项研究指定的显微结构证据部分熔融的地壳岩石的阴极发光。

Quantitative evaluation of rock structures in micro- to meso-scale has been in progress. This study recognizes the importance of quantitative analyses of such structures to understand the dynamics of the solid earth. The results of individual study are independent, which is separately described as follows.1) Mesoscale layering observed in the igneous rocks have a spacing law similar to the Liesegang rings in which diffusion of precipitating materials controlls the process. This discovery provides a strong constraint to account for the formation of such layerings.2) Two competitive schools have tried to explain the origin of snowball structure of garnet. This study revealed the structure employing a new technique combined with conventional phase petrology. Several new features were obtained and they evaluated the validity of one of two schools as an origin of the structure.3) This study specified the microstructural evidence for partial melting of the crustal rocks using cathodoluminescence.
