Cumulate plagioclase appears abruptly at the base of the F unit, which rests on an erosional disconformity .

堆积的斜长石在位于侵蚀假整合之上的F单元的基底突然出现。

The sandstones of the Turpan Basin belong mostly to graywacke and their compositional and textural maturity are generally low,indicating a strong erosional and rapid transportational environment.

吐-哈盆地的砂岩主要属杂砂岩类，总的结构成熟度和成分成熟度均较低，形成于强烈剥蚀、快速搬运的沉积环境中。
