青海省锑矿成矿规律分析

An Analysis of Antimony Mineralization Regularity in Qinghai Province

锑(Sb)为银白色的金属,性脆,无延展性。在自然界中主要存在于硫化物矿物辉锑矿(Sb_2S_3)中。60%的锑用于生产阻燃剂,而20%的锑用于制造电池中的合金材料、滑动轴承和焊接剂。至目前为止我省已发现与锑有关的矿产地38处,中低温热液型为主要成矿类型,锑矿累计查明资源储量10.80万t,保有资源储量10.52万t,约占全国资源储量的3.69%,位于全国第7位。全省热液型锑矿主要在碎屑岩地层中分布,集中分布在秦岭弧盆系,海南—黄南地区,其次在中北祁连地区、扎多—巴颜喀拉山口、两湖—昆仑山口有零星分布。海南—黄南地区为我省主要的锑工业矿床集中分布的地区,是我省重要的锑成矿区。

Antimony （Sb） and the silver-white metal is brittle and not malleable. In natron, it is mainly found in the sulfide mineralstibnite （SbzS3 ）. 60% of the antimony is used to produce fire retardants and 20% of the antimony is used in the manufactre of alloy materials, sliding bearings and solders in batteries. So far, 38 mineral deposits related to antimony have been found in the province. The medium and low temperatm~ hydrothermal ore is the main metallogenic type. It is found out that antimony deposits have accumulated a total of 10.8 million tons and the reserves of resources are 10.52 million tons by taking up about 3.69 percent of the countreg resources. It is the 7th in the country. The hydrothemlal antimony deposits are mainly distributed in clastic rocks. The concentration distribution is in Hainan-Huangnan area of Qinling arc basin system. Secondly, there are sporadic distribution in the Qilian area of north central places, including the Zhaduo-Bayan HarMountan and the Hunan and Hubei-Kunlun Mountain. Hainan-Huangnan area, an important antimony deposit in our province, is the main distribution area of antimony industre deposit in our province.
