How to Identify Sandstone

24/04/2017Sandstone is sand turned to rock. It forms when grains of sand from existing rock or crystals become cemented together over time and involves two basic stages. The first stage is marked by the accumulation of sand that usually settles out of suspension. The second stage involves the compaction of the sand from the

Sandstone

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments.. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series.Like uncemented sand, sandstone may be any color due to impurities

Cementation (geology)

Large volumes of pore water must pass through sediment pores for new mineral cements to crystallize and so millions of years are generally required to complete the cementation process. Common mineral cements include calcite, quartz or silica phases like cristobalite, iron oxides, and clay minerals, but other mineral cements also occur.
