Studied marbles occurring in the stone quarry near Nižný Klátov, Slovakia are parts of amphibolites. They form a lithologic member of the Klátov complex of Gemericum. Marbles contain fragments of amphibolites and feldspar porphyroblasts. The colour of marbles is grey light to greyish green. The rock has a massive texture and granoblastic structure. The identified mineral association of marbles forms calcite + amphiboles (magnesio-hornblende, pargasite, ferri-tschermakite, actinolite) + clinopyroxenes (diopside) + albite + orthoclase + epidote-supergroup minerals + titanite. Actinolite has a Mg/(Mg+Fe) (X_Mg) ratio in the range 0.55 - 0.85. In the dark zone of actinolite, Mg²⁺ contents increase (from 3.102 to 3.889 apfu) and Fe²⁺ contents decrease (from 1.068 to 1.766 apfu), while in the light zone the Mg²⁺ contents decrease (from 2.868 to 3.284 apfu) and the Fe contents increase (from 1.615 to 2.071 apfu). With an increasing ratio of tschermakite molecule, the ratio of X_Mg decreases to 0.50. The clinopyroxenes have a high ferrous diopside composition with an X_Mg ratio of 0.54 to 0.60. The composition of titanite is close to the end member without any significant substitution, Al content is max. 0.07 apfu, Fe³⁺ is below 0.02 apfu. Max. 0.05 apfu of Na is founded in the orthoclase, contents of Ca and K together in the albite is below 0.01 apfu. Epidote-supergroup minerals form two compositional trends. The first trend is the epidote-clinozoisite divided into three groups: 1. Epidotes containing Fe³⁺ 0.80 - 0.95 apfu; 2. Epidotes to clinozoisites containing Fe³⁺ 0.47 - 0.63 apfu; 3. Clinozoisites containing Fe³⁺ below 0.03 apfu. The second trend is a REE-enriched epidote containing 0.40 apfu. In the dark zone of the epidote, a higher Al³⁺ content (0.363 - 0.604 apfu) and a lower Fe³⁺ content (0.382 - 0.633 apfu) are present. In the light zone of the epidote, a higher Fe³⁺ content (0.802 - 0.952 apfu) and a lower Al³⁺ content (0.011 - 0.175 apfu) are present. Calcite is chemically pure; the presence of dolomite has not been confirmed. Marbles are products of local metamorphic proces-ses that were randomly generated in the tectonic zones of amphibolites.
