| 摘 要： | 元素在流/熔体间的交换、分配过程是岩浆热液矿床形成的重要环节，作为与岩浆活动有密切成因联系的典型矿种之一，锡在花岗质熔体和流体中的存在形式、分配行为及其影响因素是认识其成矿机理的关键。锡在花岗质熔体和流体中的分配特征不仅受温度、压力、氧逸度等条件的制约，流体组成和熔体的NBO/T（非桥氧键/桥氧键）、碱含量、AlK/Al(总碱与铝含量比)也是制约锡分配行为的重要因素；挥发分F、Cl对锡在流体、熔体中的地球化学行为影响尤为明显。

| Abstract: | The distribution of elements between melts and coexisting aqueous fluids plays an important role in magmatic hydrothermal ore-forming process. Tin ore is one of the representatives related to granitic magma evolvements. Cognition of tin species in granitic silicate melts, fluids and the partition coefficients is a key to recognition of the mechanism of tin ore-forming. The distribution of tin between granitic silicate melts and fluids is not only influenced by temperature, pressure, oxygen fugacity, but hlso controlled by NBO/T,Alkali and Alkali/Aluminium of melts and the content of fluids. Tin geochemical characteristics in melts and fluids are influnced significantly by different contents of volatiles fluorine and chlorine. |
