Striking platform

In lithic reduction, the striking platform is the point on the proximal portion of a lithic flake on which the detachment blow fell; this may be natural or prepared. Types of striking platforms include:

  • Cortex, which consists of an area of cortex used as a platform during initial reduction;
  • Single-faceted, consisting of a flat platform at right angles to the dorsal surface of the flake and most often associated with conchoidal fractures;
  • Double-faceted, a variety of multifaceted, prepared platform, also characteristically flat and associated with conchoidal fractures;
  • Multifaceted, with three or more facets to the platform;
  • Lipped, a platform type resulting from soft hammer biface reduction; and
  • Crushed, which occurs when the platform was crush beyond easy recognition by the detachment blow.
