X-Ray Diffraction patterns of <0.2 micrometer size fraction of gouge material from Tatra Mountains, Poland

X-Ray Diffraction (XRD) patterns of oriented mounts of Ca-saturated <0.2 micrometer size fraction of clay gouge material from selected shear zones in Tatra Mountains, Poland. The data sets contains patterns of air-dry and glycolated samples. This is Research Data associated with the manuscript "Extraction of 40Ar-39Ar ages from a multicomponent mixture: a case study from the Tatra Mountains, Poland", authored by Artur Kuligiewicz, Michał Skiba, Marek Szczerba, Chris M. Hall, and Dorota Bakowska, which is submitted to Clays and Clay Minerals.
