Sediments consolidated
The consolidated sediments are deposits which were formed by secondary sedimentation of previously weathered rocks and redeposition of their fragments, and/or by chemical and biochemical precipitation from solutions. Later, they have been consolidated during a diagenesis. During diagenesis following processes leading to consolidation are in operation: compaction, cementation, recrystallization, intrastratal solution, metasomatism, and authigenesis. The intensity of diagenesis depends mostly on the depth of burial, hydrostatic and oriented pressure of surrounded rocks, on temperature, solution activity and some additional factors. The transformation of sand into sandstone serves as one of examples of consolidation during diagenetic processes.
