Structures of the fibrous dolomite crystals in methane seep carbonates from Marmorito, northwest Italy

Samples were made into 100 μm rock slices. Points of interest were aligned to the beam and measured with φ scans +/− 25° at χ = 0°, 30°, 60° and 90°, respectively. Stepsize of φ was 1° and exposure time was 10 seconds. Results were converted to powder diffraction diagrams by the CrysAlisPro software package.

将样品制备为100 μm岩石薄片。将各感兴趣点与入射光束对准，分别在χ=0°、30°、60°和90°的条件下，采用±25°范围的φ扫描进行测量；φ扫描步长为1°，曝光时长为10秒。最终结果通过CrysAlisPro软件套件转换为粉末衍射图谱。
