It is usually organic rock but also occur inorganically as a chemical precipitate or a diagenetic replacement. It occurs as nodules, concretionary masses, and as layered deposits. In the finer-grained rocks, mineralogical composition is often difficult to determine and interpret. Suppose we look at a sandstone with a hand lens (Figure 7.71). Quartz, and perhaps K-feldspar, may be easy to find. However, lithic fragments can be confusing and small grains of chert or magnetite may be impossible to identify.Chert has four diagnostic features: the waxy luster, a conchoidal (shell-shaped) fracture of the silica mineral chalcedony that composes it, a hardness of seven on the Mohs scale, and a smooth (non-clastic) sedimentary texture. Many types of chert fit into this categorization. 01 of 16 Flint Nodule James St. John/Wikimedia Commons/CC BY 2.0Paleozoic Cherts Tuscaloosa Gravels Tallahatta Orthoquartzites Tallahatta Agates Kosciusko Orthoquartzites Cockfield Orthoquartzites Glendon Limestone Catahoula Orthoquartzites Hattiesburg Orthoquartzites High Terrace Gravels Ironstone Petrified Wood Pre-loess Terrace Gravels Mississippi River Alluvium Gravels Piedmont Quartz Clay ResourcesBt1--16 to 22 inches; yellowish red (5YR 5/6) gravelly clay; few fine distinct yellowish brown mottles; moderate fine subangular blocky structure; firm; plastic; about 30 percent angular chert gravel; many distinct clay films on faces of peds; few fine roots; few fine pores; few fine dark brown manganese concretions; very strongly acid; clear ...As a kid, I remember seeing chert roads on and around my grandparents' farm in Tennessee.

(2 to 4 inches thick)Eurycea tynerensis is paedomorphic in streams containing large chert gravel, but metamorphoses in nearby streams containing poorly sorted, clastic material such as sandstone or siltstone. Conclusion: Deposits of large chert gravel create loosely associated streambeds, which provide access to subsurface water during dry summer months.Aeolian, sometimes spelled eolian or œolian, are deposits of windblown sediments. Since wind has a much lower carrying capacity than water, aeolian deposits typically consist of clast sizes from fine dust to sand [ 52 …
