The process of chemical and physical change in deposited sediment during its conversion to rock.

di′a·ge·net′ic (-jə-nĕt′ĭk) adj.


1. (Geological Science) the sum of the physical, chemical, and biological changes that take place in sediments as they become consolidated into rocks, including compaction and cementation, but excluding weathering and metamorphic changes
2. (Chemistry) chem recrystallization of a solid to form large crystal grains from smaller ones
diagenetic adj


(ˌdaɪ əˈdʒɛn ə sɪs)

the physical and chemical changes occurring in sediments between the times of deposition and solidification.
di`a•ge•net′ic (-dʒəˈnɛt ɪk) adj.
