| abstract | The palaeomagnetic directions of seven Dutch fireplaces are compared with the archaeological age estimates which
range from the first to the 17th century AD. A comparison with the British master curve of secular variation for
archaeomagnetic dating results in a refinement of the archaeological age estimates in two cases, while four other
archaeological age estimates can be confirmed. For one fireplace only one sample is reliable, resulting in a very
poorly defined archaeomagnetic age of 2 to 3 centuries younger than the expected age (i.e. late Middle Ages).
On the other hand, accepting the archaeological age estimates, the palaeomagnetic directions can contribute to the
database that is used to construct the British secular-variation master curve. We applied the classification grades
proposed by Tarling & Dobson (1995) which range from unreliable (grade 1) to reliable (grade 5). Three fireplaces
have grades 5, one has grade 4, one grade 3, one grade 1 and for one case no grade was assigned. |
