Abstract:

北祁连山西段熬油沟地区奥长花岗岩具有与高硅埃达克岩相似的地球化学特征高SiO2,富Na2O(高Na/K),高Sr/Y,高(La/Yb)N,Sr正异常,相对富集大离子亲石元素(LILE)和轻稀土(LREE),亏损Nb,Ta和Ti.锆石SHRIMP定年结果为438±3Ma,表明其形成与北祁连古洋壳的俯冲有关,但其形成时间明显晚于北祁连山榴辉岩的变质时间(460~490Ma).Sr-Nd同位素结果显示其ISr和εNd(t)值分别为0.7044~0.7047和+3.0~+4.1,暗示其来源于新生的洋壳物质.结合北祁连造山带的构造演化背景,熬油沟奥长花岗岩可能是俯冲板片变质成榴辉岩后,在折返过程中发生近等温或升温减压熔融,在大约60km深度熔融形成.
