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。
South Qinling Barium large-scale mineralization, rich in barium minerals. Based on the investigation of the electronic probe of the ore and mineralized rocks in the barium mineralization belt of barium metallogenic belt in South Qinling and the previous research results, it is found that the barium in the large barium metallogenic belt in the South Qinling is mainly barite, witherite and barium Stone, rhodochrousite, barite, Hanjiang stone, Ankang ore, barium iced feldspar, vanadium mica and other forms; sulfide mainly pyrite, and contains a small amount of acicular nickel ore, sphalerite, sulfur Vanadium copper, blue chalcopyrite, bornite. In addition, a small amount of vanadium titanium oxide was found. On the basis of studying the chemical composition of barium minerals, the genesis of barium minerals such as witherite, bariaolite, rhodochrosite, barite and barium vernalite are discussed.
