Concept
Lithic core
Summary
In archaeology, a lithic core is a distinctive artifact that results from the practice of lithic reduction. In this sense, a core is the scarred nucleus resulting from the detachment of one or more flakes from a lump of source material or tool stone, usually by using a hard hammer precursor such as a hammerstone. The core is marked with the positive scars of these flakes. The surface area of the core which received the blows necessary for detaching the flakes is referred to as the striking platform. The core may be discarded or shaped further into a core tool, such as can be seen in some types of handaxe.
The purpose of core reduction may be to rough out a blank for later refinement into a projectile point, knife, or other stone tool, or it may be performed in order to obtain sharp flakes, from which a variety of simple tools can be made. Generally, the presence of a core is indicative of the latter process, since the former process usually leaves no core. Because the morphology of cores will influence the shape of flakes, by studying the core surface morphology, we might be able to know more information about the dimensional flake attribute, including their length and thickness. Cores may be subdivided into specific types by a lithic analyst. Type frequencies, as well as the general types of materials at an archaeological site, can give the lithic analyst a better understanding of the lithic reduction processes occurring at that site.
Lithic Cores may be multidirectional, conical, cylindrical, biconical, or bifacial. A multidirectional core is the product of any random rock, from which flakes were taken based on the geometry of the rock in any pattern until no further flakes could be removed. Often, multidirectional cores are used in this way until no obvious platforms are present, and then are reduced through bipolar reduction, until the core itself is too small to produce useful flakes. Conical cores have a definite pattern. One flake was removed from a narrow end of the tool stone, and this was then used as the platform to take flakes off in a unifacial fashion all around the edge of the rock.
