摘要
西天山乌拉斯泰地区的中泥盆世沉积被定名为汗吉尕组,过去认为它属于滨-浅海相,近年笔者在该地层中发现了大量的枕状玄武岩及其相伴的深水槽谷型沉积,改变了过去的认识。
The Middle Devonian sediment in the Wulasitai area in the west Tianshan is named Hanjiga Formation, which was thought to be littoral -neritic facies in the past. In the recent years, the writer discovered a great deal of pillow form basalt with abyssal rift basin deposition in the stratum. It changes the understanding in the past and is of noticeable implication in geology.
