Index of occurence in Slovakia: 1. EXCEPTIONAL 1 - 2 localities 2. RARE 3 - 6 localities 3. INFREQUENT 7 - 15 localities 4. ABUDANT 15 - 50 localities 5. MORE ABUDANT > 50 localities

Identification rating of mineral in Slovakia: 1. WELL IDENTIFIED - mostly combination at least 2 most distinguished analytical methods (X -ray diffraction and electron microprobe) 2. PARTIALLY-INDENTIFIED - mineral mostly analyzed, but for well identification is need to make another analyses 3. UNDERIDENTIFIED - mineral mostly identified only visual, often very problematic or fictive
