Data for: Oxygen isotopic compositions of end-members in a multicomponent mixture: a case study of the Ediacaran weathering material from the East European Craton

X-Ray Diffraction Patterns of disoriented preparations (bulk rock and clay fractions) and oriented preparations (clay fractions) from samples used in the paper. Na - samples after dissolution of carbonates with sodium acetate–acetic acid buffer treatment. HD - samples after dissolution of carbonates and dissolution of free iron (hydr)oxied with buffered sodium dithionite – citrate – bicarbonate treatment. KD - samples after dissolution of carbonates and dissolution of kaolinite with hot NaOH treatment. Oriented preparations: Air - samples in the air-dry state; GLY - samples after glycolation.
