ARCHAEOMAGNETIC DATING AT PUEBLO-GRANDE

One hundred and seventy-four archaeomagnetic samples from burned featu res were collected at Pueblo Grande, a Hohokam site in Phoenix, Arizon a. This large data set yields an excellent opportunity to evaluate the potential contribution of archaeomagnetism to solving chronometric pr oblems. It allows a consideration (1) of different sampling schemes, ( 2) of the archaeomagnetic quality of samples that do and do not produc e archaeomagnetic dates, (3) of samples that do not date according to archaeological expectations, and (4) an analysis of the factors that i nfluence dating precision. Further, comparing 109 and 19 of the archae omagnetic dates with associated ceramic and radiocarbon dates provides measures of the accuracy of archaeomagnetic dates.
