南秦岭大型钡成矿带,钡矿物种类丰富。通过对南秦岭钡成矿带钡矿床中矿石和矿化围岩的电子探针研究,结合前人研究成果,发现南秦岭大型钡成矿带中钡主要以重晶石、毒重石、钡解石、菱钡镁石、钡长石、汉江石、安康矿、钡冰长石、钒云母等形式存在;硫化物以黄铁矿为主,并含有少量的针镍矿、闪锌矿、硫钒铜矿、蓝辉铜矿、斑铜矿。此外,还发现少量钒钛氧化物。在研究钡矿物化学组成的基础上,对毒重石、钡解石、菱钡镁石、钡长石、钡冰长石等钡矿物的成因进行了探讨。
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.
