Electron microprobe study of V, Co, Ni and Au admixtures in ore minerals from Fe-Ti-V deposits (NE Poland). A b s t r a c t. The main objective of this study was to quantitatively and qualitatively idenify trace metal admixtures in ore minerals from Fe-Ti-V ore deposits within the Suwa³ki Anorthosite Massif in NE Poland. Chemical composition of ore minerals was determined using the CAMECA SX-100 electron microprobe and scanning electron microscope. The most abundant trace elements were Ti and V hosted in oxides and Co, Ni, Cu, Zn contained in sulphides such as pentlandite, pyrrhotite, chalcopyrite, pyrite, siegenite, millerite. Scarce occurrences of native Bi, hessite and greenockite were identified. Samples, which were depleted in iron oxides were enriched in REE due to the presence of zircon, apatite and monazite. |
