It is formed when layers of minerals, fine sediment along with skeleton fragments and shells of marine organisms go through lithification

in marine stromatolites and hypersaline mats.
This facies probably originated in the upper slope environment where early lithification
allowed intraclasts to be incorporated into flows.
The importance of mechanical compaction in reducing porosity and causing lithification
is stressed by Cyziene et al.
Boring algae micrite envelopes and lithification
of molluscan biosparites.
Thermal analysis of basalt containing ceramic masses showed that with increasing amounts of basalt an increase in mass loss, which, in our opinion, is connected with the content of aqueous minerals in basalt (hlorofeit), which is saturated with water lithification
of residual melt.
Today, chemical scientists are mostly dealing with analysis of the structure and composition of the organic constituent and inorganic minerals present in oil shale, as well as the molecular structure of kerogen and lithification
characteristics of inorganic minerals.
Also included well recrystallized and run down nerideids, turritelid shells, and fragments of a crustacean pincer, which clearly indicate lithification
previous to reelaboration (Fig.
Quartz grains in sandstone beds of the third member--the Carbon Canyon Member--are set in carbonate, silica, hematite, or chlorite cement or clay matrix, which in itself would indicate a long, diverse history of deposition and lithification

in the Red Chalk and Lower Chalk of eastern England: a bacterial control model and its implications.
Hence, the barite roses postdate the deposition and lithification
of the Garber Sandstone, though the ages of the geologic structures with which the barite roses are most closely associated are still unknown.
The existence of such a structure indicates that the calcareous mud was originally deposited in a calm, shallow, and deep area where rock lithification
