Description/Abstract | This patent describes the method for longitudinally dividing an elongated stratigraphic sample comprising a core enclosed within a tube to expose the interior.^ The improvement comprises the steps of: orienting a cutting means comprising a continuous circulating cutting edge in a substantially horizontal plane; positioning the longitudinal axis of the sample in a plane substantially parallel with the cutting edge; bringing the sample and cutting edge into contact with one another to divide the sample into an upper section and a lower section; receiving the upper section as the sample is divided in a receiving means positioned immediately adjacent to and co-planar with the cutting means; providing continuous and uninterrupted support for the upper section as sample is divided, without deflecting upper section from lower section; and whereby the physical integrity of the interior surface of the sectioned core is preserved. |
