文摘 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。
其他语种文摘 The distribution of elem ents between melts and coexisting aqueous fluids plays anim portan trole to magm atic hydrotherm alore forming process. Tinore is one of the representatives related to granitic magma evolve ments. Cognition oftin species in granitic si licate m elts,fluids and the partition coefficients is a key to recongnizing the mechanism of tinore form ing. The distrib ution of tin between granitic silicate melts and fluids is not only influenced by tem perature,pressure,oxygen fugacity ,but also controlled by NBO/T 、Alkali and Alkali/Alum inium of melts and the contentoffluids. Tin geochemic alcharacteristics in melts and fluids are inf lunced significantly by different contents of volatiles fluorine and chlorine.
