Submicron-scale structures of natural omphacitic pyroxenes in high-grade blueschists and low-temperature hydrous eclogites were examined using high resolution microscopy and laser Raman spectroscopy. This study confirmed that the anti-phase domain size of undeformed omphacite within garnet porphyroblast had high potential for geospeedometer. However, inorder to apply this method, further understanding of disequilibrium growth of omphacite and garnet in low-temperature metamorphic rocks are required.

利用高分辨显微镜和激光拉曼光谱研究了高品位蓝片岩和低温含水榴辉岩中绿辉石的亚微米尺度结构。研究证实，石榴子石变斑晶中未变形绿辉石的反相畴尺寸具有很高的地质速度计潜力。然而，为了应用该方法，还需要进一步了解低温变质岩中绿辉石和石榴石的不平衡生长。
