accumulation layer

Thus we can infer that Nihewan ape-man may either rest under the bare cliff of the Gorge Area or be buried in the marsh country or deep in the lake bed, or in the accumulation layer of the cavern.

由此推测，泥河湾大猿人或沉睡于沟壑区的裸崖下，或葬身于沼泽地带和湖底，或安葬于山洞的堆积层里。

In recent years, by shooting China's cities, I have interpreted the accumulation of city memories layer by layer.

这几年，我通过拍摄中国的都市，一层一层地解读了都市记忆的堆积。

An accumulation of associated parts create gaps both horizontally and vertically, leading the eye through surprising escapes that result in a complex layer of various sequences.

相关部分的堆积在水平和垂直方向创造了间隙，带领视线穿过令人惊讶的出口，结果形成各种秩序的复杂层次。
