New techniques for obtaining information from lithic artifacts have burgeoned over the last few decades, but most are still in various stages of development, and are not yet routinely used by archaeologists. This paper argues that such new techniques will develop most rapidly and successfully if there is constant interplay between methodology and application; that is, between studies designed to increase our understanding of the physical, chemical, or biological processes underlying the technique to significant archaeological problems.

As an example, trace element data from the Midwest and Northeast are used both to elucidate specific aspects of prehistoric cultures in those areas, and to study the geochemistry of trace elements in chert.
