Archaeomagnetic and paleomagnetic dating techniques rely on the fact that the earth's magnetic field varies over archaeological dating: stratigraphy and seriation. Archaeomagnetic studies have been employed as a dating technique in the british isles for the last 50 years, using the record of the ancient geomagnetic field recorded by fired archaeological materials. Eleven archaeomagnetic samples were collected from several sites near porco, bolivia as part of the proyecto arqueológico porco-potosí these samples were collected in order to 1) explore the availability of appropriate sample materials in the bolivian andes, and 2) assess the feasibility of pursuing reference curve research for this region.
