Sandstone - Wikipedia
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. [1] Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's ...

2024年10月30日 · Sandstones are first subdivided into two major textural groups, arenites and wackes. Arenites (the front triangular panel of Figure 4) consist of a sand-size framework component surrounded by pore spaces that are either empty (in the case of arenite sands) or filled with crystalline chemical cement (in the case of arenites).

Based on hardness and color, four main types of sandstone can be recognized: (1) gray sandstone, (2) crystallized sandstone, (3) hard sandstone and (4) carbonate cemented sandstone. Gray Sandstones are a mixture of dark and light grains yielding a rock that is gray in color and usually not as hard as other kinds of sandstone.
