总结了硼及硼同位素的地球化学特征：（１）硼是易溶元素，主要赋存在地球表层，尤其是海水、海相沉积物及海水交代岩石中。其同位素组成δ１１Ｂ值按顺序变化，封闭盐湖卤水（＞４０‰）＞海水（３９５‰）＞海相硼矿物（１８２‰～３１７３‰）＞海相沉积物（１３９‰～２５２‰）＞海水交代岩石（４５１‰～１０８５‰）。大陆水及陆相沉积物硼含量及硼同位素组成变化极大，并多以负值为主。海陆过渡构造带则具有过渡的硼丰度值和硼同位素组成。（２）１１Ｂ较１０Ｂ具有更活跃的地球化学性质，因此在水岩作用中具有明显的同位素交换。硅化交代作用中，岩石被硅化交代，释放硼，并优先释放重硼，同位素组成变轻；在脱硅反应中，岩石释放硅吸收硼，并优先吸收重硼，同位素组成变重。在封闭体系中，水溶液淋滤岩石中部分的硼，即可大量富集，并富集１１Ｂ；在开放体系中，岩石硼被大量淋滤流失，δ１１Ｂ值明显降低。由于水岩作用的结果，从新鲜海底玄武岩到正常海水，硼同位素值从－２９５‰到３９５‰逐渐升高。（３）变质脱水反应中硼被大量排出，并优先排出重硼同位素，进入流体相，因此随着变质程度由低到高，岩石中硼含量及同位素组成δ１１Ｂ值由高变低。（４）在成矿研究中?
Summarized the geochemical characteristics of boron and boron isotopes: (1) Boron is a soluble element, mainly in the Earth’s surface, especially the seawater, marine sediments and seawater account rock. The δ11B values of the isotopic composition change in sequence, and the salt lake brine (> 40 ‰)> seawater (395 ‰)> marine boron minerals (182 ‰ ~ 3173 ‰)> marine sediments (139) ‰ ~ 252 ‰)> seawater to explain rocks (451 ‰ ~ 1085 ‰). The boron content and boron isotopic composition of the continental water and continental sediments vary greatly, and mostly dominated by negative values. The continental-continental transition zone has a transition boron abundance and boron isotopic composition. (2) 11B has more active geochemical properties than 10B, and therefore has obvious isotopic exchange in water rock. In the silicification metasomatism, the rocks are replaced by silicification, releasing boron, releasing heavy boron preferentially and reducing the isotopic composition. In the desiliconization reaction, the rock releases silicon to absorb boron and preferentially absorbs heavy boron, making the isotopic composition heavier. In the closed system, the aqueous solution leaches some of the boron in the rock to be abundantly enriched and enriched in 11B; in the open system, the rock boron is leached by large amounts of leaching and the δ11B value is significantly reduced. As a result of the water-rock effect, the boron isotope value gradually increases from -2.95% to 39.5% from fresh sea basalt to normal seawater. (3) In the metamorphic dehydration reaction, boron is expelled in a large amount, and heavy boron isotopes are preferentially discharged into the fluid phase. Therefore, as the metamorphic degree changes from low to high, the δ11B value of boron in the rock decreases from high to low. (4) in mineralization research?
