在闽东南平潭和漳州火成杂岩中，广泛发育岩浆混合现象，表现为花岗质岩石中存在辉长－闪长质同深成岩墙和淬冷岩石包体。花岗质和闪长质岩石中普遍存在Ａｎ＞７０％的斜长石捕虏晶。这种成分的斜长石是辉长岩特有的，而不是任一种花岗岩的斑晶。在斜长石捕虏晶四周，都有与花岗岩中的斜长石成分相当的斜长石加生膜。斜长石捕虏晶可分为自形的、熔融状、筛孔状和碎片状等四类，它们各自形成于不同的动力环境 Magma mixing occurs extensively in Pingtan and Zhangzhou volcanic complexes in the southeastern Fujian Province, showing gabbro-dioritic plutonic diagenetic wall and quenched rock inclusions in granitic rocks. An> 70% plagioclase xenolith is widespread in granitic and dioritic rocks. The plagioclase of this composition is unique to gabbro rather than the plaque of any granite. Around plagioclase xenoliths have plagioclase associated granite plagioclase composition. Plagioclase xenocrysts can be divided into four categories: self-shaped, fused, sieve-like and debris-like, each formed in a different dynamic environment
