Archaeomagnetic studies in the Gorgan Plain in Northern Iran. This paper will report on new directional magnetic data obtained from recent studies of fired archaeological materials and sediments from northern Iran. It will discuss the palaeosecular variation record available in this poorly covered region and will address the archaeological questions that can be answered by such studies. Samples for magnetic directional studies have been obtained from archaeological features in the Gorgan Plain of northern Iran , including ovens, hearths, brick kilns and water-lain sediments. These are shown to retain a stable record of the past magnetic field, with well-defined and precise magnetic directions, and to provide an indication of palaeosecular variation.
