The Application of Reflectance Spectroscopy to Chert Provenance of Mississippian Symbolic Weaponry (2013)
DOCUMENT Full-Text Ryan Parish.

Dissertation that examines the non-destructive application of visible/near-infrared and Fourier transform infrared spectroscopy to chert sourcing. The study also examines the provenance of material used to manufacture a sample of Middle Mississippian sword-form bifaces.

The Application of Relfectance Spectroscopy to Chert Provenance of Mississippian Symbolic Weaponry
PROJECT Uploaded by: Ryan Parish

Determination of the source of chert artifacts ties past peoples to specific locations on the landscape either through direct or indirect procurement strategies allowing researchers to visualize interactions with both resources and people. However, due to inherent variability accurate provenance data often remains elusive. The reliance upon chert provenance data obtained through macroscopic techniques is problematic and emphasizes the importance of continued research and development of...

Chert Spectral Database (2013)
DATASET Ryan Parish.

The spreadsheet consists of three booklets. The first reports all visible/near-infrared spectra recorded on all 1,050 chert samples analyzed in the project. The second reports all middle-infrared reflectance spectra recorded for the 1,050 chert samples. The third booklet reports both visible/near-infrared and middle-infrared spectra non-destructively recorded upon 30 Mississippian sword-form biface artifacts. Rows represent an individual sample/artifact while columns are the wavelength...

Chert Spectral Database (2013)
DATASET Citation Only Ryan Parish.

Chert spectral database collected from over 1,000 Lower St. Louis "Dover" and Fort Payne chert samples. Database used to evaluate the chert provenance application of both VNIR and FTIR reflectance spectroscopy techniques. The spectral data was also used to characterize the source for 30 Mississippian chert sword-form bifaces.

Evaluating Fourier Transform Infrared Spectroscopy as a Non-Destructive Chert Sourcing Technique
PROJECT Uploaded by: Ryan Parish

The visual and chemical similarity between some chert types and individual outcrops within the same geologic formation often hinders accurate provenance determination. Fourier Transform Infrared (FTIR) reflectance micro-spectroscopy is a non-destructive method demonstrating potential application in chert sourcing. Prior to analysis of archaeological assemblages the accuracy of the technique and analytical methodology must be tested. The current study examines a sample database of two visually...

FTIR reflectance spectral chert database (2012)
DATASET Ryan Parish.

Hyper-spectral data obtained from 121 chert samples: 60 Ft Payne (30 from Elco, IL; 30 from Florence, AL), 60 Dover (30 from the Brigham Quarry site, TN; 30 from the Thompson Hollow Quarry site, TN), and a single Mookaite chert sample from Australia used as a control. Also included in the spreadsheet are spectral averages of each sample set from a single location. I sheet is 10 spectra taken from a single Dover chert sample and 4 spectra from three color zones in the Mookaite sample....

Lithic Procurement Patterning as a Proxy for Identifying Late Paleoindian Group Mobility along the Lower Tennessee River Valley (2015)
DOCUMENT Citation Only Ryan Parish.

The Tennessee and Cumberland River Valleys boast some of the highest concentrations of diagnostic Paleoindian artifact finds in the Americas. However, many of these finds are from secondary contexts void of associated deposits. The study utilizes chert provenance data, obtained using reflectance spectroscopy, on a large sample of Late Paleoindian diagnostic bifaces from sites along the Lower Tennessee River Valley. The objective of the study is to visualize group mobility at the close of the...
