A new contribution to the archaeomagnetic study of a Roman pottery kiln from Calahorra (Spain)

Abstract

Results from archaeomagnetic research on a Roman pottery kiln are presented. In a previous paper (Pares et al. 1992), a collection of samples from the kiln's heating chamber was studied and palaeodirection results were obtained. In the same paper, dating was performed on the basis of the secular variation reference curve of the inclination at Paris. In the present study, the palaeointensity was evaluated on the basis of the same collection of samples. The mean value obtained is 60.9pT. A comparison of this value with other available archaeointensity values, obtained from neighbouring territories, confirms the date estimated by Pares et al. ( 1992kthe middle of the 1st Century AD.

Recent achievements in archaeomagnetic dating in the Iberian Peninsula: application to Roman and Mediaeval Spanish structures

“…The establishment of an intensity reference curve can also help to dating purposes, especially in the case of displaced objects, where only the archaeointensity, and occasionally the inclination can be obtained. Some archaeointensity studies have been performed in Spain (Kovacheva et al, 1995;Nachasova et al, 2002aNachasova et al, ,b, 2007Burakov et al, 2005Burakov et al, , 2006Burakov et al, in press;Gómez-Paccard et al, 2006c). Despite these efforts, the existing archaeointensity data set for Iberia remains poor and only eight archaeointensity values are available for the last two millennia.…”

Continuous geomagnetic field models for the past 7 millennia: 1. A new global data compilation

“…We used a large upgraded compilation of data from Bulgaria [ Kovacheva , 1997, and personal communication]. Data from France [ Thellier and Thellier , 1959; Shaw , 1979; Veitch et al , 1984; Hedley and Wagner , 1991; Chauvin et al , 2000; Genevey and Gallet , 2002] and Spain [ Kovacheva et al , 1995; Nachasova et al , 2002] have been grouped in one file together with few data from Switzerland [ Thellier and Thellier , 1959; Veitch et al , 1984; Hedley and Wagner , 1991] and Germany [ Hedley and Wagner , 1991]. British intensity data have been published by Weaver [1966], Shaw [1974], Walton [1977], Games and Baker [1981], Games and Davey [1985], Boyd [1986], and Aitken et al [1988].…”

Variations in the geomagnetic dipole moment over the last 12 000 years

“…For the European region, the new data (after 1982) come from Bulgaria and Yugoslavia (Kovacheva & Kanarchev 1986; Kovacheva et al (1995, personal communication, 1997), Greece (Odah et al 1995; Hussain 1983, 1987) and other parts of Europe (summarized in Aitken et al 1988, 1989). From the rest of the world the data are from Japan (Sakai & Hirooka 1986), China (Wei et al 1982, 1986, 1987; Tang et al 1991; Yang et al 1993a,b), Peru (Gunn & Murray 1980; Yang et al 1993c; Shaw et al 1996) and North America (Sternberg 1989).…”
