There are three basic types of sedimentary rocks. Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Examples include: breccia, conglomerate, sandstone, siltstone, and shale.Examine the rock specimens provided by the instructor and fill in the table bel Use the three sedimentary environment tables Tables 6.1,6.2, and 6.3) to idemo all possible sedimentary environments for each rock specimen.

Chert occurs mostly in carbonate sedimentary rocks as nodules or layers. Flint is a dark-colored variety of chert.^ Coal is a combustible rock containing more than 50% by weight of carbonaceous material. Coal in most cases is a lithified peat.Microscopic quartz crystals often form chert seams and nodules as silica-rich groundwater moves through a variety of sedimentary and metamorphic rocks. Chert precipitated from silica-rich groundwater can also replace bone and wood present in sediment and sedimentary rocks, often even preserving the materials’ original cellular structure.
