Siliceous rock, any of a group of sedimentary rocks that consist largely or almost entirely of silicon dioxide (SiO2), either as quartz or as amorphous silica and cristobalite; included are rocks that have formed as chemical precipitates and excluded are those of detrital or fragmental origin.
The most common siliceous rock is chert, which is a dense, microcrystalline rock composed of chalcedony and quartz. Chert is the second most abundant chemically precipitated rock after limestone. It occurs in beds and in nodules. Bedded chert consists of siliceous fossils such as diatoms and radiolaria, which form siliceous oozes on the sea floor. As these organisms sink, portions of their shells dissolve near the bottom and reprecipitate in void spaces between shell fragments, resulting in a hard bedded rock. Bedded cherts are common in areas enriched in silica-bearing organisms, as for example near volcanoes where volcanic glass is rapidly altered to produce high-silica concentrations. Similar processes occur in freshwater lakes associated with volcanoes.

Quartzite is a silicious rock.
Silicious rock:
- Silicious rocks are those rocks which are composed of more than 75% silica.
- Quartzite is a silicious rock which is formed from the metamorphism of sandstone.
- It is a hard and durable rock that is resistant to weathering and erosion due to its high silica content.
- Quartzite is used as a construction material, decorative stone, and as a source of silica for the production of glass and ceramics.
