The flakes are shaped using the lithic reduction techniques, allowing for creation of various tools such as arrowheads and handaxes. Two stone characteristics will determine whether one is able to chip away large enough flakes to make tools out of: whether the stone is of a cryptocrystalline structure, and how conchoidally the stone fractures ...
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 features (such as noting the presence or absence of cortex, for example).
While many worked stone tools can be technically designated as "modified flakes," for lithic analysis purposes a modified flake is usually defined as a lithic flake with one or more edges that were altered either through opportunistic use or through nonsystematic retouching; it is often difficult to identify the process that produced the observed edge.

Using satellite imaging and sediment core analysis, researchers found the 64 kilometres (40 mi) waterway was crucial for transporting materials and labor for pyramid construction. The branch which was about 0.5 kilometres (0.31 mi) wide with a depth of at least 25 metres (82 ft) disappeared likely due to drought and desertification .
The theoretical return period between occurrences is the inverse of the average frequency of occurrence. For example, a 10-year flood has a 1/10 = 0.1 or 10% chance of being exceeded in any one year and a 50-year flood has a 0.02 or 2% chance of being exceeded in any one year.
Some claim that they can determine the sort of tools used to create the debitage. Others feel it is possible to effectively estimate the work-hours represented, or the skill of the workers based on the nature of the debitage. Debitage analysis of biface reduction can be used to determine what stage of reduction is represented in waste.
Polygonal masonry is a technique of stone wall construction. True polygonal masonry is a technique wherein the visible surfaces of the stones are dressed with straight sides or joints, giving the block the appearance of a polygon.
