reactions involving the rock and connate fluids in which parts of the matrix are filled by scale or mineral growths or removed and become high permeability flow channels.

n: the chemical and physical changes that sedimentary deposits undergo (compaction, cementation, recrystallisation, and sometimes replacement) during and after lithification.

the process of forming a sedimentary rock from the clastic grains. May also be in conjunction with several geochemical processes such as cementation reactions and chemical dissolution.

n: 1. a cavity in a rock. 2. a small cavern, larger than a pore but too small to contain a person. Typically found in limestone subject to groundwater leaching.

a large open pore feature. May be associated with chemical dissolution of part of the matrix over geologic time.
