| 摘 要： | 报道了崂山钙碱性岩套和碱性岩套花岗岩中角闪石的矿物成分及其变化特征，在此基础上，追索其物理化学条件的演变与成岩意义。指出，角闪石的成分及其变化特征在两个岩套中的差异，指示两个岩套岩浆可能有其独立的岩浆起源，同时也经历了不同的岩浆演化路径，分别受不同的物理化学条件制约。

| Abstract: | The compositional characteristics and its variation of amphiboles taken respectively from two different granitic groups (Calc alkailine group and Peralkailine group) of Laoshan granitods, are reported in the paper. The rock forming conditions and the significance of compositional variation of hornblendes are also discussed, and summerized as follows. The differences of the compositional variation of the amphiboles bettween the two different granitic groups indicate that the two groups of Laoshan granitoids originated in their own independent magmatic sources, experienced different differencial paths, and were restricted by different physical and chemical conditions. |
