【摘要】 南岭燕山早期复式岩体早阶段花岗岩是独立的一期侵入岩体,而不是一个相带。早阶段花岗岩的岩石酸度较低、岩浆分异程度较低。侵位较深。具来源除L部地壳成因物质外,还不同程度地混合有下部地壳或上地幔成因物质。属(?)(?)型和“S”型的过渡类型成因的花岗岩。更多还原

【Abstract】 The early stage granite in the complex bodies of the early Yanshanian period in Nanling, which may be an independent rock body, while isn’t as a phase-zone of rock body.The early-stage granite is characterized by a low acidity, a low grade magmatic differentiation and a deeper seated emplacement, it s material source came not only from the upper crust but also from the lower crust or the upper mantle.The early stage agranite belong to transitional type" between " I" type and "S" type granite.更多还原
