In the United States archaeomagnetism has been used primarily              as an archaeological dating technique and has seldom been used to               study the Earth's magnetic field.  This project will use well-                  dated archaeological sites to acquire archaeomagnetic data                      relating to three problems: 1) the direction and intensity of the               field at spot locations in the Western Hemisphere between 1550 and              1800 A.D., 2) the continuous record of directional changes in the               American Southwest from 200 B.C.. to 1800 A.D., and 3) the record               of intensity changes over the past 10,000 years in North and South              America.  In each case archaeomagnetism can clarify important                   questions about the behavior of the Earth's magnetic field that                 have arisen from recent advances in the study of historical                     records, rapidly-deposited sediments and lava flows.  Although                  standard archaeomagnetic procedures will be followed during the                 course of the investigation, an important additional component                  will be detailed studies of the magnetic mineralogy and rock                    magnetic properties of various samples.  These studies, which have              never been done systematically for archaeomagnetic materials, will              provide a firmer paleomagnetic basis for the measurements which we              make and will provide new insights into the relative merits of                  different archaeological materials and archaeomagnetic techniques.
