ARCHAEOMAGNETIC DATING ON THE GREAT-PLAINS

Archaeomagnetic dates are given for 41 samples from numerous archaeolo gical sites on the Central, Southern, and High Plains. The archaeomagn etic samples are dated using the U.S. Southwest curve, because no curv e exists for the Plains area Both visual and statistical archaeomagnet ic dates are provided and ''modified statistical dates '' are derived to address current problems with the statistical dating method. Plains sample quality is discussed, and samples colected from hearths inside structures are found to produce better archaeomagnetic results than s amples from open campsite hearths. The archaeomagnetic dates are compa red to radiocarbon dates and archaeological expectations for the sites from which the samples were collected, and give favorable results for precision and accuracy. Archaeomagnetism is seen as a useful addition to available dating techniques for Plains sites.
