| Tartalmi kivonat: | In 1995/96 complex study on ore minerals occurring'in a 7 cm thick vein traversed in the drilling Baksa 2 at 186.4 m depth was made in the Department of Mineralogy, Geochemistry and Petrology of the Attila József University (Szeged, Hungary) to determine their mineralogical and genetic features. In this paper, results of ore microscopic study and those of the inclusion analyses are published. The ore vein is massive sulphide one (almost its 60 % is composed by sulphide ore). Two phases can be distinguished in the vein by both ore microscopy and inclusion analysis. The outer ore phase is quantitatively subordinate. Its mineral paragenesis: chalcopyrite, galena, sphalerite, pyrite (marcasite). The inner ore phase represents the main mass of the vein; its minerals: pyrite (marcasite), sphalerite, chalcopyrite, pyrrhotite. Pyrite (marcasite) and sphalerite are the quantitatively most dominant minerals. The dominant non-ore minerals are quartz and carbonate minerals. Possibly, the vein was formed in closed system at low pressure in a temperature interval ranging from" 250 to 310 C°. A two-phase formation can be supposed. It is most likely that fluids forming the ore vein are differentiates of a real magmatic melt. Identification of the regional connection is quite difficult, however, it can be brought into connection with either the Permian volcanism in the Villány Mountains or an unknown independent volcanic activity. |
