1. A method comprising identifying a depositional form of a mineral phase in a sedimentary rock sample based on a measurement of a parameter indicative of a size of crystallites of the mineral phase in the rock sample, wherein the measurement of the parameter indicative of the size of crystallites of the mineral phase in the sedimentary rock sample is obtained by powder X-ray diffraction.
