Racine County is underlain by Silurian sedimentary rocks, primarily dolostones. Quarries can yield some well-crystallized specimens, such as the find of smoky calcite, marcasite and other minerals at the Vulcan Materials Corporation (classically the Ives)Quarry near Racine. Exposures of this rock can yield interesting Silurian fossils from reefs and associated environments. Thick glacial sediments obscure the bedrock in most places. At least one "drift diamond" has been found in the county (Burlington). Beach combing along Lake Michigan's shore can provide interesting samples of local and glacially transported rocks.
