Corrections of Archaeological Magnetic Anomalies of the El Caño Pre-Columbian Site, Panama

Abstract

Normally, the results of a magnetic prospection are presented under the form of an image on a scale of gray colors where the tones of the gray color is proportional to the measured parameter. Such image can be a great help in Archeology because it could reveal the presence and/or absence of cultural features buried at few depth. However, due to diverse factors, the most important anomalies could show certain level of distortion. This work presents the result of the magnetic data corrections obtained at an archaeological pre-columbian site through statistical processes and logarithmic compression. Because of this, it was possible to reduce the zigzag and spike effects.
