Iowa's rock record is noted for its abundance of carbonate rocks. These carbonate rocks, limestones and dolomites, contain interesting textural features and an abundance of fossils. The fossils can often be removed from the rock matrix and studied. The fossils can also be studied in cut and polished slabs of rock or by making thin sections of the rock. Thin sections are prepared by cutting a thin slice from the rock and gluing the slice on a glass slide. The rock slice is then ground-down with abrasives to a thickness of .030 mm., covered with a coverslip, and studied with a microscope.
