摘　　要：目前市场上蓝宝石主要有二种成因 ,即碱性玄武岩中岩浆成因和由侵入体与白云质大理岩接触交代成因。着重从成矿的地球化学特征 ,温度、压力等成矿条件方面 ,探讨两种成因蓝宝石成分中钛、铁含量的不同而影响蓝宝石蓝色色调的差异。There are primarily two genetic type sapphires in current jewelry market,one is of magma genesis and existed in alkali basalt,and the other is of contact metasomatic genesis caused by the intrusion and dolomitic marble.On the basis of the former researchs on Ti and Fe concentration and colouring mechanism,this paper mainly explores the difference of blue tone under the influence of Ti and Fe concentration of different genesis' sapphires in the respects of geochemistry feature and metallogeny factors (temperature,pressure,etc)
