简介：ZargatNa'是戒指建筑群外面在埃及的东南的沙漠收割Shalatin城市的90kmNW。戒指建筑群形成在包围mafic-ul-tramafic山上面高站的一条突出的山脉。它被主要打击NNW-SSE和E-W的关节和差错的二个集合切，并且被堤，斑状的碱的正长岩，和霏细岩斑岩注射。它由碱正长岩，碱石英正长岩，和花岗石的忍受peralkalinearfvedsonite和pegmatitic堤和基石组成。建筑群被极端丰富在REE，黑钨矿和稀罕的、高域力量金属(HFSM)局部地描绘，例如ZrandNb。最高的集中(1.5wt%Zr，0.25wt%Nb，0.6wt%ΣREE)发生在钠角闪石伟晶岩附近形成了的inaegirine钠长石细晶岩。招待石英在钠角闪石融化包括花岗石和伟晶岩提供不含糊的证据碱的作文和稀罕金属丰富是的per主要magmatic特征。在石英晶体的玻璃包括也包括Nb有不兼容的痕量元素的高集中(750x10~(-6)),Zr(2500x10~(-6))和REE(1450x10~(-6))。REE，Nb和aegirine钠长石细晶岩的Zr作文主要作为melt包括，和Y/Ho比率阴谋一样的线性丰富趋势displayunfractionated，near-chondritic价值。化学药品并且组织上aegirine-albiteaplites的特征从在从residualperalkaline的不稳定的损失以后的快速的结晶化是显然结果的花岗石融化在到melt包括的作文类似。
