Abstract
The generalization and cadastral systematization of data on the Nikolaevskii manifestation of scheelite mineralization (Right-Bank Region of the Ukrainian Shield) were made. The cadastral data regarding the Nikolaevskii wolframite mineralization are grouped in four tables. In total, 43 cadastral attributes are determined: 11 cadastral attributes – in relation to spatial characteristics of mineralization; 18 cadastral attributes – in relation to geochemical peculiarities; 9 cadastral attributes – in relation to mineralogical description of scheelites; 5 cadastral attributes – in relation to chemical and X-ray identification of scheelites. The peculiarities of the scheelite mineralization of the Nikolaevskii area: 1) localization in the rocks of the Zelenorichenska suite of the Ingulo-Inguletsk series (Lower Proterozoic); 2) linear-lenticular form of tungsten anomalies and zonal character of anomalies of small metals; 3) direct correlation of tungsten with CaO and Na2O in rocks; 4) presence of transverse zonality of mineralization – W, (Mo, Bi), Ag, (V, Cu, Sn), Zn; 5) stratiform sulfide-scheelite with molybdenite type of mineralization; 6) practically pure composition of scheelite individuals (no impurities); 7) association with pyrite, pyrrhotite, chalcopyrite, molybdenite, magnetite, apatite, leucoxene; 8) removal of barium from tungsten-bearing zones and surrounding areas.
