Additional data points from archaeomagnetic samples with corresponding dating techniques such as tree ring dating or carbon dates, help refine the regional curves. These artifacts of occupation can yield the magnetic declination from the last time they were fired or used.

The sixteen original papers in many cases represent the work of individuals who have been intimately involved with the development and refinement of archaeomagnetic dating techniques. In general, many cultures used long-term fire hearths made of clay bricks, or a space lined with clay, that were baked into place by use. The samples are sent to an Archaeomagnetic Laboratory for processing.

Within these weaker areas the local directions and intensities change gradually secular variation. Raw data is provided in an appendix. Inquire Requests The University of Arizona Press is proud to share our books with booksellers, media, librarians, scholars, and instructors.

As the only single volume devoted to the subject, it will serve as the standard reference in the field. Case histories consider both successful and unsuccessful applications of the technique in New World fieldwork. Each of the samples is measured in a spinner magnetometer to determine the thermal remanent magnetism of each sample. The magnetic declination at any given time can be frozen into a clay formation that contains magnetite and is heated above the Curie point.

The Archaeomagnetic Laboratory at the Illinois State Museum has secular variation curves for the southwest, mid-continent and southeast United States. Southwest Archaeomagnetic Reference Curve.

This involves sufficient mass to take samples from, and a suitable material with adequate magnetite to hold the remnant magnetism. Learn more about submitting a proposal, preparing your final manuscript, and publication. These samples are marked for true north at the time of collection.
