Occurrences of Fe mineralization in the vicinity of Trsino аnd Pekljani, Vinica (Eastern Macedonia)

The latest field and laboratory examinations of the Fe mineralization in the vicinity of Trsino and Pekljani offered a new understanding of the mineralization associated with the quartz-chlorite sericite schists and metamorphosed granites. The hosts to iron mineralization are hematite, specularite, magnetite and martite. Latest microscopic studies carried out, in part in electron microprobe, made possible a more complete understanding of the characteristics of the major ore minerals. These studies determined, for the first time, the composition of the major as well as some new minerals. Structural-textural features of ores were also studied in detail for the first time and made it possible to define the successive order of mineralization and the genetic type of ore mineralization. Macroscopic and microscopic studies of samples from Trsino and Pekljani distinguished striped and stockwork-vein-impregnated textures, the most common structures being those of replacement type (corrosive, pseudomorphic and metacrystal-line)
