This study investigated potential sources of lithic raw |
|
materials utilized by prehistoric hunter-gathers in the |
|
vicinity of Fort Bragg in the North Carolina Sandhills. |
|
The study was designed to achieve two main objectives: |
|
(1) to evaluate the effectiveness of a range of |
|
mineralogical and chemical techniques for fingerprinting |
|
potential sources of raw materials and (2) to apply these |
|
techniques in determining for sources of ancient stone |
|
tools found at Fort Bragg. Seventy-one rock samples from |
|
12 different quarry zones, along with nine prehistoric |
|
artifacts, were examined using five different techniques: |
|
petrography, neutron activation analysis (NAA), neodymium- |
|
isotope analysis. x-ray fluorescence (XRF), and |
|
inductively coupled plasma mass spectrometry (ICP-MS). |
|
Each technique provided useful information, but there |
|
were significant discrepancies among the assignments of |
|
geological sources using the different lines of evidence. |
|
The two most useful techniques proved to be petrography |
|
and Nd-isotopic analysis. although the elemental data |
|
were also very helpful in certain cases. |
