Figure 2, from Core Section 330-10-1, for in-stance shows how cone structures develop progressively from horizontally laminated shaly limestone upwards through a layer of cones of small amplitude to a layer of essentially fibrous calcite over a distance of less than 5

CORE Core Bits Scientific Application. A core bit (Fig. 1, Fig. 2) is a drilling tool with a hole through the center that removes sediment rock and allows the core pedestal to pass through the bit and into the core barrel.The Ocean Drilling Program (ODP) employs different coring systems and bits to obtain continuous cores in all types of oceanic sediments and igneous basement.

Rock Quality Designation (RQD) (ASTM D6032) is a modified core recovery percentage in which the lengths of all sound rock core pieces over 100 mm in length are summed and divided by the length of the core run. Pieces of core that are not hard and sound should not be included in the EQD evaluation even if they are at least 100 mm in length.
