Testing Geophysical Anomalies Using In Situ Shallow Subsurface Spectroscopy and Soil Magnetic Susceptibility Analysis

Summary

This is an abstract from the "Quivira Revisited" session, at the 84th annual meeting of the Society for American Archaeology.

In 2015 the National Park Service’s Archaeological Prospection Workshop was held at the Tobias Site (14RC8). Students and instructors evaluated the site using a variety of non-invasive prospection methods ranging from landscape-level LiDAR analysis to high sample density subsurface geophysical survey. The evaluation identified buried features and patterning within the site along with previously unknown components of the site. In 2016 geophysical anomalies identified during the workshop were tested using a Veris Technologies P4000 instrument which obtains soil spectra in the visible/near infrared region (350-2250 nm), electrical conductivity, and insertion pressure. The P4000 is a mobile probe that is pressed down into the soil up to a 1-meter depth. A 3-D array of spectra is obtained on a north-south and east-west grid. Representative soil cores were also collected during the study for chemical and magnetic susceptibility analysis. This poster will present the spectral, magnetic and chemical results by combining the data using chemometric analysis, which will correlate these data sets and use them to build a 3-D model of buried archaeological features.
