New Method for Study of Calci-Phosphatic Pellets
Hydrofluoric acid treatment of opaque calci-phosphatic pellets renders them translucent. Details of internal structures, such as size, composition, configuration of nucleus, and number and thickness of growth bands, can readily be studied in any number of specimens. This facilitates comparison by horizon and locality, of genesis and growth of pellets, bottom conditions, and paleoecology in large pellet-populations.
