Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.

Red lava rocks look good with hen-and-chicks plants ( Sempervivum tectorum) when they turn red, for example, while white flowers contrast nicely with black lava rocks. Lava rocks are also well-suited to fire pits . Sandstone Basics. Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock.

Figure 7.71: Examining a rock with a hand lens. In the coarser-grained clastic rocks, the compositions of lithic fragments give clues to the origin of the sediment. In the finer-grained rocks, mineralogical composition is often difficult to determine and interpret. Suppose we look at a sandstone with a hand lens (Figure 7.71).

May 10, 2019 · Quartzite is a tough stone composed mostly of quartz. It may be derived from sandstone or from chert by regional metamorphism. This metamorphic rock forms in two different ways. In the first way, sandstone or chert recrystallizes resulting in a metamorphic rock under the pressures and temperatures of deep burial. Several of the rock layers in the canyon are of terrestrial origin, including the Hermit Shale, Supai Group, Coconino Sandstone, and Surprise Canyon Formation. The mudstones and siltstones of the Hermit Shale and Supai Group were laid down by a meandering system of rivers and streams in a semi-arid climate about 280 million years ago.

The grain size, sorting, compaction, and degree of cementation of the rocks all influence primary porosity. For example, poorly sorted and well-cemented sandstone and well-compressed mudstone can have very low porosity. Some examples of sedimentary rocks are shale, limestone, and sandstone.
