It suffered from the action of the rain and from plants growing in the heated material.

The present study has been conducted in order to increase the archaeomagnetic database and fill the temporal gap around 900 AD.
For this purpose 14 ovens have been sampled for their paleaomagnetic signals.
The dating process follows the descriptions given by , which is based on the combination of temporal probability density functions of the three geomagnetic field elements.
Here, we develop an interactive tool in Matlab code to carry out archaeomagnetic dating by comparing the undated archaeomagnetic (or lava flow) data with a master PSVC.
The Earth's field changes in both strength (intensity) and direction over time.
An alpha-95 value greater than 5° is generally considered to represent a poor precision, while values less than 2.5° are considered to indicate a good precision.
A Matlab tool for archaeomagnetic dating has been developed in this work.
Well-dated palaeosecular variation curves (PSVCs) can be used to date archaeological artefacts with unknown ages.
Abstract : The Early Medieval valley settlement of Thunau am Kamp in Lower Austria has been under archaeological excavation for 10 years.
The site was occupied during the 9th and 10th centuries AD according to potsherds, which seem to indicate two phases of activity: in the older phase ovens were placed in the corners of houses while during the younger phase they are found in the middle of the wall.
