While sandstone is a sedimentary rock, quartzite is a metamorphic rock that is comprised almost entirely of quartz. Quartzite actually forms from quartz-rich sandstone that is altered under intense pressure and heat deep in the earth. When the sandstone is subjected to these conditions, metamorphism occurs, recrystallizing the quartz grains and ... A siltstone is a lithified, non-cleavable mudrock. In order for a rock to be named a siltstone, it must contain over fifty percent silt-sized material. Silt is any particle smaller than sand, 1/16 of a millimeter, and larger than clay, 1/256 of millimeter. Silt is believed to be the product of physical weathering, which can involve freezing and thawing, thermal …

Siltstones differ significantly from sandstones due to their smaller pores and a higher propensity for containing a significant clay fraction. Although often mistaken for a shale, siltstone lacks the laminations and fissility along horizontal lines which are typical of shale. [2] Siltstones may contain concretions.
