a kind of chemical sedimentary rock

• Obsidian

• Limestone

• Coal

• Compaction

The process in which pressure from the upper layers of sediment pushes down on the lower layers, causing the sediments to stick together and form solid rock.

• Cementation

• Compaction

• Melding

• Welding

The process in which minerals hold sediment together, like glue, making a detrital sedimentary rock.

• Cementation

• Compaction
