摘　　要：浙江天姆尖盆地存在Ⅰ ,Ⅱ两类流纹岩 ,这两类流纹岩可能是由同一母岩浆经过结晶分异演化而来的 。There are two types of rhyolites with different characteristics,in the Tianmu jian basin,Zhe jinag province.They are both possible formed in the process of crystallization differentiation of the same crust and mantle contaminated magma,however,their characteristic and location are very different.
