基于同步辐射的傅里叶变换红外光谱和拉曼光谱以亚微米空间分辨率应用于萨特磨坊陨石的多个颗粒，该陨石是具有CM 1和CM 2岩性的风化角砾岩。拉曼和红外活性官能团揭示了有机和矿物组分的性质和分布，并证实SM 12达到了比SM 2更高的变质温度。碳酸盐与有机质的空间分布呈负相关。的空间分布的脂肪族有机质和OH相对于SM 2中的硅酸盐的分布不同，从SM 12，支持一个假设，即萨特的磨坊的母体是一个组合的多个机构具有不同的起源。高脂族CH 2/CH 3的比率确定的带强度的SM 2和SM 12颗粒是类似的IDP和较少改变的碳质方解石，它们显着高于其他CM方解石和弥漫ISM对象。
Synchrotron‐based Fourier transform infrared spectroscopy and Raman spectroscopy are applied with submicrometer spatial resolution to multiple grains of Sutter's Mill meteorite, a regolith breccia with CM1 and CM2 lithologies. The Raman and infrared active functional groups reveal the nature and distribution of organic and mineral components and confirm that SM12 reached higher metamorphism temperatures than SM2. The spatial distributions of carbonates and organic matter are negatively correlated. The spatial distributions of aliphatic organic matter and OH relative to the distributions of silicates in SM2 differ from those in SM12, supporting a hypothesis that the parent body of Sutter's Mill is a combination of multiple bodies with different origins. The high aliphatic CH2/CH3 ratios determined from band intensities for SM2 and SM12 grains are similar to those of IDPs and less altered carbonaceous chondrites, and they are significantly higher than those in other CM chondrites and diffuse ISM objects.
