砂岩是使用最广泛的石材之一,在许多地质序列中都很常见,而且易于用于建筑目的。在建筑方面,砂岩比许多其他石头有一个优势,那就是它可以很容易地沿着现有的沉积层用基本的手工工具进行切割。砂岩也可以看作是外行人最了解的石头,基本上是沙子粘合在一起形成石头。对地质学家来说,这与事实相去甚远。砂岩的组成颗粒的性质不同,可能在大小、成分、形状、粗糙度和溶解程度上存在差异,而颗粒本身可能分布在不同的带中,水泥的质量和类型可能是可变的,并且可能存在不同数量和形式的基质材料。所有这些因素自然会影响给定砂岩作为尺寸石的表现。
Sandstone is one of the most widely used stone materials, being both common in many geological sequences, and easy to use for construction purposes. In construction, an advantage that sandstone has over many other stones is the ease by which it can be split, using basic hand tools, along existing sedimentary planes. Sandstone might also be regarded as the stone that is most understood by the layperson, basically sand cemented together to form stone. For the geologist this could not be further from the truth. Sandstone varies in the nature of the constituent grains that may have differences in size, composition, shape, roughness and degree of dissolution, whilst the grains themselves may be laid down in variable bands, the quality and type of cement may be changeable, and matrix materials of differing quantity and form may be present. All these factors naturally affect how a given sandstone performs as a dimension stone.
