拉曼光谱在变质岩石学中有广泛的应用，为地质和构造研究提供了许多机会。最小的样品制备保留样品的完整性和微结构信息，而使用共聚焦显微镜允许空间分辨率下降到微米级。拉曼光谱清晰地区分矿物多晶型，为变质条件，特别是超高压条件提供了关键的限制。拉曼光谱还可用于监测变质岩中碳质物质的结构。结构的变化对温度敏感，因此碳质材料的拉曼光谱被广泛用于测温。拉曼光谱还可以检测和量化微包裹体中的应变，提供新的晴雨表，可以应用于了解变质和构造过程，而不需要任何化学平衡的假设。
Raman spectroscopy is widely applied in metamorphic petrology and offers many opportunities for geological and tectonic research. Minimal sample preparation preserves sample integrity and microtextural information, while use with confocal microscopes allows spatial resolution down to the micrometer level. Raman spectroscopy clearly distinguishes mineral polymorphs, providing crucial constraints on metamorphic conditions, particularly ultrahigh-pressure conditions. Raman spectroscopy can also be used to monitor the structure of carbonaceous material in metamorphic rocks. Changes in structure are temperature-sensitive, so Raman spectroscopy of carbonaceous material is widely used for thermometry. Raman spectroscopy can also detect and quantify strain in micro-inclusions, offering new barometers that can be applied to understand metamorphic and tectonic processes without any assumptions about chemical equilibrium.
