一九五九年,我们在小秦岭普查脉金时,在碳酸盐石英脉中发现一种白色粉末状团块物质,经取样分析含锶量高。一九七一年,我们又选择了一条较大的脉进行了检查,经鉴定认为是天青石风化的产物。天青石新鲜面为米黄色,半透明,晶面弯曲,呈壳层状。折射率Ng为1.632-1.634。其中Sr为33.74％,Ba为10.92％。天青石中硫酸锶和硫酸钡呈类质同像存在,硫酸钡组成格架,硫酸锶充填于格架之间。在氧化带中,天青石极易风化成白色粉末,当硫酸
In 1959, we found a white powdery mass in the carbonate quartz vein at the time of the census of the Qinling Mountains. After sampling, it was found that there was a high amount of strontium contained. In 1971, we chose a larger vein for inspection, which was identified as the product of celestite weathering. Celadon fresh surface is beige, translucent, crystal surface curved, shell-like. The refractive index Ng is 1.632-1.634. Sr is 33.74% and Ba is 10.92%. Celestite strontium sulfate and barium sulfate were similar to the existence of homogeneous, barium sulfate composition grid, strontium sulfate filled in the grid between. In the oxidation zone, celestite weathering easily into white powder, when sulfuric acid
