地质学家杰拉德·邦德注意到，一些沉积物颗粒被氧化铁染色，这表明它们起源于冰川覆盖红砂岩露头的地方。
Geologist Gerard Bond noticed that some of the sediment grains were stained with iron oxide, evidence that they originated in locales where glaciers had overrun outcrops of red sandstone.

本文用红砂岩试件做了一系列的试验，探讨了在多轴压缩下红砂岩的强度和变形特征。
Systematic tests were conducted on specimens of red sandstone under polyaxial compression, and the strength and the deformation characteristics were carefully investigated.

红砂岩
红砂岩主要呈粒状碎屑结构和泥状胶结结构两种典型结构形式，因胶结物质和风化程度的差异，其强度的变化大。多数红砂岩在挖掘或爆破出来后，受大气环境的作用可崩解破碎，甚至泥化，故其岩块的大小及颗粒级配将随干湿循环的时间过程而变化，其物理力学性质也将产生变化。
