【摘要】 钠硼解石是一种常见的硼酸盐，主要分布在南美和我国青藏高原盐湖中，以及土耳其西阿纳托里亚（ＷｅｓｔＡｎａｔｏｌｉａ）硼矿和美国西部Ｋｒａｍ ｅｒ硼矿中。它是青海盐湖硼矿的主要矿石类型。由于自然界未发现在水体中析出的钠硼解石，因而，其成因仍是不清楚的。从放置３ 年、８ 年和１４ 年的小柴旦湖矿坑水、湖表卤水和扎仓茶卡湖表卤水获得了钠硼解石，从而查明钠硼解石是在稳定平衡条件下的低浓度、弱碱－ 碱性、富硼的硫酸钠亚型水体中形成的。这对于阐明钠硼解石矿床的成因及其人工控制再生均有重要的意义更多还原

【Abstract】 Ulexide is a common borate.It is mainly distributed in some salt lakes (salars) of South America and Qinghai-Xizang plateau of China, as well as the Tertiary boron deposits of Turkish west Anatolia and American Kramer.It is a mine ore type of boron deposits in salt lakes of Qinghai Province.However,it is not found in nature that ulexide is precipitating from water bodys up to now. So its origin is still not clear .We have obtained ulexide from the mine- pit water and surface brine of Xiao-Qaidam Lake and surface brine of Zhazang Caka Lake, for 3 years,8 years and 14 years reservation respectively.Conclusion was drawn that ulexide formed in low-concentration,weak-basicity,and B-rich water badys of sodium sulphate subtype under stable equilibrium conditions. It is important in illustrating the formation of ulexide and its atificial regeneration control.\;更多还原
