中文摘要	银硐粱早古生代花岗闪长岩分布在北祁连造山带东段屈吴山地区,侵入于原阴沟群和前寒武纪变质岩系中。它与米家山、扁强沟、清凹山以及南华山花岗岩类共同构成长约220千米的构造—花岗岩带,沿 NW-NWW 向展布。地球化学研究结果表明,银硐粱花岗闪长岩具有典型的高镁埃达克岩的地球化学特征,它们具有富 Na 贫 K,SiO_2>56%,Al_2O_3>15%,Na_2O>4.0%(4.51%～4.92%),K_2O(1.96～2.77%),Na_2O/K_2O=1.63～2.40,属钙碱性侵入岩;高 Sr(599～691×10~(-6)),低 Y(6.3～8.1×10~(-6)),Sr/Y>40(81～9...
