Abstract：There are various kinds of barium minerals in a large Ba metallogenic belt in the Southern Qinling Mountains. Through electron microprobe analyses of ores and mineralization for Ba-deposits in the large barium metallogenic belt, combining with previous research results, we conclude that barium has a variety of occurrence, such as barite, witherite, barytocalcite, norsethite, celsian, hanjiangite, ankangite, hyalophane, rosceolite and so on. Pyrite is the main sulfide, meanwhile millerite, sphalerite, sulvanite, digenite, bornite can be also seen. Besides, there are some vanadium and titanium oxides. The genesis of the Ba-minerals was also discussed in this paper.
