You can also find many fossils of sea creatures preserved in the rock, like trilobites, brachiopods, and crinoids. ALEX LEONARD. The layers from top (rim) to bottom (river): Kaibab Limestone; Toroweap Limestone ; Coconino Sandstone; Hermit Shale Chemical sedimentary rocks, like limestone, halite, and flint, form from chemical precipitation. A chemical precipitate is a chemical compound—for instance, calcium carbonate, salt, and silica—that forms when the solution it is dissolved in, usually water, evaporates and leaves the compound behind.Limestone is a sedimentary rock in the class known as chemical sedimentary rocks. It is composed chiefly of calcite, CaCO 3, and constitutes about 10 percent of all sedimentary rocks. Limestone may form inorganically or by biochemical processes.
