Microburin
Encyclopedia
A microburin is a characteristic waste product from manufacture of lithic tools, sometimes confused with an authentic burin
Burin
Burin from the French burin meaning "cold chisel" has two specialised meanings for types of tools in English, one meaning a steel cutting tool which is the essential tool of engraving, and the other, in archaeology, meaning a special type of lithic flake with a chisel-like edge which was probably...

Upper Paleolithic
The Upper Paleolithic is the third and last subdivision of the Paleolithic or Old Stone Age as it is understood in Europe, Africa and Asia. Very broadly it dates to between 40,000 and 10,000 years ago, roughly coinciding with the appearance of behavioral modernity and before the advent of...

 who defined it as «a type of angular, smooth, with a terminal retouch in the form of a small notch». Breuil initially thought that the microburins had a functional use as a type of microlithic burin. However, he later came to realize that the manufacturing technique was different from that of the burin and that they could be waste products from the manufacture of microliths, but the may have occasionally been reused for a useful purpose.

A microburin is a fragment of a lithic flake
Lithic flake
In archaeology, a lithic flake is a "portion of rock removed from an objective piece by percussion or pressure," and may also be referred to as a chip or spall, or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a core. Once the proper...

, or more precisely, of a lithic blade, that shows on its upper face the beginnings of a notch terminating in an oblique flection (whose surface can only be seen from the lower side) that ends in a very acute trihedral apex. As stated earlier, it was thought that microburins were functional microliths, but carving experiments, along with the reassembly of pieces with perfectly aligned edges have demonstrated that they were a characteristic waste of a technique called microburin technique
Microburin technique
The microburin technique is a special procedure for cutting up lithic blades which yields fragments that can be used in the manufacture of utensils. The usable fragments are basically geometric microliths. This technique has been recorded through the Old World, from at least the Mesolithic...

Lithic analysis
In archaeology, lithic analysis is the analysis of stone tools and other chipped stone artifacts using basic scientific techniques. At its most basic level, lithic analyses involve an analysis of the artifact’s morphology, the measurement of various physical attributes, and examining other visible...
