Computed Tomography: Application in Studying Biogenic Structures in Sediment Cores

The study of biogenic structures in cores is hampered by the facts that the structures are generally exposed only on vertical surfaces, and that the area available for study is limited by typically small core diameter. Computed tomography (CT) gives a three-dimensional picture by producing a series of bedding-parallel sections. The detailed serial sectioning of cores by CT will allow reconstruction of the tiering relationships of deep-water trace producers.
