Diagenesis - Wikipedia

Diagenesis (/ ˌ d aɪ ə ˈ dʒ ɛ n ɪ s ɪ s /) is the change of sediments or existing sedimentary rocks into a different sedimentary rock during and after rock formation (lithification), at temperatures and pressures less than that required for the formation of metamorphic rocks.

Sedimentary rock - Wikipedia

Sedimentation may also occur as dissolved minerals precipitate from water solution. ... Minerals in a sedimentary rock can have formed by precipitation during sedimentation or by diagenesis. In the second case, the mineral precipitate can have grown over an older generation of cement.
