| 摘 要： | 新疆阿克陶红蓝宝石矿床含矿岩石具有典型的眼球状、条带状混合岩化构造。浅色脉体中的钾长石有序度很低，属单斜正长石，其中部分发育钠长石出溶条纹。基体中出现富铝矿物矽线石和电气石，黑云母中Ａｌ２Ｏ３含量高；斜长石Ａｎ值低，为钠长石。含矿岩石为富铝贫硅低钙质岩石。脉体中的红蓝宝石晶体中发现大量流体熔融包裹体。红蓝宝石矿床为混合岩化作用成因，形成于高温低压条件下

| Abstract: | The gemmiferous rocks in ruby and sapphire deposit of Aketao (Xinjiang) are characterized by augen and banded structures of migmatization. The potassium feldspar with perthitic albite in the leucosome is much disordered ( δ =0 1265) and belongs to orthoclase. Some Al 2O 3 rich minerals as sillimanite and tourmaline are found in the melanosome. Biotite in the melanosome is with high Al 2O 3 content ( w B=18 37%～20 18%) and plagioclase is with low An value, which is albite. The gemmiferous rocks are Al 2O 3 rich, SiO 2 poor and CaO low. Abundant fluid melt inclusions are found in the crystals of ruby and sapphire. The deposit is formed by migmatization with high temperature and low pressure. |
