| 摘 要： | 白旗碎斑熔岩中斜长石以更长石为主，其有序度低，指示了岩石高温火山成因的特征，从岩体边缘相到中心相至根部相，长石类型，化学成分和有序度具有一定的变化规律，反映了岩体不同岩相带成岩条件的差异性。

| Abstract: | Plagioclase in porphyroclastic lava from Baiql area is chiefly oligoclase. It is low inordering degree. This indicates a high rock--forming temperature. In order of marginal faciestransition factes~central factes~root factes, the ordering degree of the plagioclase tends to increase, implying different rock--forming conditions for different factes. |
