中文摘要	华北克拉通北缘西段中元古代花岗岩类仅见于查干础鲁-霍尔森构造带以南的雅布赖-巴音诺尔公构造带中,整体上受NEE向长寿命线性构造控制。据岩性可分为斜长花岗岩和石英闪长岩两类。斜长花岗岩为S型花岗岩,但具有向I型过渡的特征,富含Cr、Ni、SiO2、Al2O3,其均值分别为672μg/g、405μg/g、71.40％和14.93％,δEu值变化大,介于0.34和3.95之间,起源于幔源岩浆与壳源物质的混合。石英闪长岩为典型的I型花岗岩,其Cr、Ni含量的均值分别为220μg/g和162μg/g,类似于华南同熔型花岗岩。斜长花岗岩中的锆石U-Pb等时线上交点年龄为1256Ma,代表了发生于华北克拉通...
