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.
