Relating to lithification; the process by which loose, unconsolidated material is turned into rock. Lithification can be accomplished by high temperatures, high pressures, or the chemical deposition of "cements" (minerals) within spaces between particles. Back

To change to stone, or to petrify; especially to consolidate from a loose sediment to a solid rock.

The process of converting sediments to solid rock, generally through cementation and/or compaction. obe A rounded, tongue-like projection of glacial drift (i.e. Des Moines Lobe).

(4) to make into rock.

to turn to rock. Several geological processes can operate to consolidate loose sediments into hard rocks. Pressure from thick sequences of overlying sediments can cause lithification; for example, loose sand turned into sandstone. Chemical changes caused by ground water can cement loose sediments into hard rocks; for example, loose sea shells and sand cemented into coquina limestone.
