Miscellaneous Studies in Hard-Hammer Percussion Flaking: The Effects of Oblique Impact

Author:

Speth John D.

Abstract

Steel balls were dropped on to massive glass prisms at an impact angle of 45° in order to determine the effects of oblique impact on several attributes of flake size and flake shape. The results indicate that a flake produced by oblique impact is shorter, but not significantly thinner (except in the immediate area of the cone), than a flake of comparable platform thickness produced by vertical impact.
