Document Summary

Raw material: all potentially flaked material as it exists in its natural state. Nodules: more or less rounded stones of flint and other fine-grained cherts. Tablets:flattish tablets of flint and other grained cherts. Blocks: other raw material types that are squarish or angular. Pebbles/cobbles : stones that have been heavily rounded due to river, marine, or glacial action. Patina: another term for surface weathering; usually alteration of a surface of the rock after it has been flaked (much lighter in color than unaltered flint). Reduction sequence : the total of the various processes for the preparation of a flint nodule, the production of flakes, and their final retouching into finished tools. Hammer: either a stone or, in later stages of reduction, a piece of antler or wood used to strike the material and remove flakes. Conchoidal fracture : the application of force initiates this fracture that cleaves though the material until it intersects an exterior surface and produces a flake.
