By what process do ooids form
WebAbstract. Ooids are subspherical carbonate sand grains, composed of concentric laminae which surround detrital nuclei. This paper is an evaluation of the usefulness of ooids as paleo-sea-level indicators. Although ooids form in a variety of shallow-marine environments they do not form precisely at sea level.
