A Multistage Geophysical Approach to Detecting and Interpreting Archaeological Features at the LeBus Circle, Bourbon County, Kentucky

摘要: Magnetic gradiometry and in-phase electromagnetic induction (EM) instruments were employed during a geophysical survey to identify archaeological features at an Adena circular ditch embankment earthwork site. Three identified in the selected for further examination because of their shape, spatial arrangement, differences gradiometer EM data. Downhole magnetic susceptibility was used explore subsurface shape these presence variations within them. Excavation exposed buried ground surface below earthwork's embankment, midden-like soil ditch, large pit situated over spring/seep inside earthwork. data collected on open wall profiles excavation units with KT9 kappameter. Pairing results helped separate lightly burned from A horizon map beneath areas where is now destroyed, natural cultural fill episodes feature. Correlations between drawn specific contexts radiocarbon dating. The chronology site indicates constructed Middle ritual development (150 bc ad 1), time marked by increasing diversity appearance structures mortuary ritual. This research also demonstrated that Woodland reused Late Fort Ancient peoples after approximately ad 1450. Copyright © 2011 John Wiley & Sons, Ltd.
