“…Directional and intensity data obtained from these materials have been used to produce reference curves for the past few millennia. Reference curves (also called master curves), which reveal the variations in the intensity of the geomagnetic field are now available for several regions, including North America, Meso-America, Eastern Asia, Eastern and Western Europe (e.g., Kovacheva, 1997;Yu et al, 2000;Morales et al, 2001;Bowles et al, 2002;Genevey et al, 2003;Soler-Arechalde et al, 2006; see also the compilations of Valet, 2003;Perrin and Schnepp, 2004;. Archeointensity data for Western Europe are concentrated on archeological sites from France (e.g., Chauvin et al, 2000;Gallet et al, 2002;Genevey and Gallet, 2002;Gallet et al, 2005) while only few results are available for the Iberian Peninsula (Kovacheva et al, 1995;Gómez-Paccard et al, 2006).…”

Geomagnetic field variations at archeomagnetic timescales can be obtained from well-dated heated structures and archeological potsherds. Here, we present the first archeointensity results obtained on Portuguese ceramics (1550 to 1750 AD) collected at Brazilian archeological sites. The results are compared to those obtained from Western Europe and currently available geomagnetic field models. Continuous thermomagnetic and IRM acquisitions curves indicate that Ti-poor titanomagnetite is responsible for the remanence in these ceramic fragments. Five fragments (24 samples) out of twelve analyzed yielded reliable intensity estimates. The row archeointensity data were corrected for TRM anisotropy and cooling rate effect. The mean dipole moments are obtained for three different age intervals: 1550±30 AD, 1600±30 AD and 1750±50 AD. Mean intensities vary from 37.9±4.2 μT to 54.8±7.6 μT in agreement with the previously reported data for 1550 AD and 1750 AD. Relatively weaker, but still highly dispersed, values were obtained for 1600 AD ceramics.

terra australis 28Terra Australis reports the results of archaeological and related research within the south and east of Asia, though mainly Australia, New Guinea and island Melanesia -lands that remained terra australis incognita to generations of prehistorians. Its subject is the settlement of the diverse environments in this isolated quarter of the globe by peoples who have maintained their discrete and traditional ways of life into the recent recorded or remembered past and at times into the observable present.Since the beginning of the series, the basic colour on the spine and cover has distinguished the regional distribution of topics as follows: ochre for Australia, green for New Guinea, red for South-East Asia and blue for the Pacific Islands. From 2001, issues with a gold spine will include conference proceedings, edited papers and monographs which in topic or desired format do not fit easily within the original arrangements. All volumes are numbered within the same series. List of volumes in Terra AustralisVolume 1: Burrill Lake and Currarong: Coastal Sites in Southern New South Wales. R.J. Lampert (1971) Volume 2: Ol Tumbuna: Archaeological Excavations in the Eastern Central Highlands, Papua New Guinea. J.P. White (1972) Volume 3 Since its inception, the conference has been an important meeting place for the widely dispersed and diverse community of Australasian archaeological scientists, including both those resident in the region, primarily in Australia and New Zealand, as well as Australasians working around the world. The 2005 meeting at ANU was the first to be held there since 1991 and was the venue for the presentation of 79 papers in 10 sessions covering all aspects of archaeological science from analytical chemistry to GIS, fire histories and ancient technology. The linking concept with all of the sessions was the integration of archaeological science research within broader archaeological projects -in other words forwarding interpretations alongside consideration of method. Over 120 delegates from 6 countries attended the lecture sessions which were accompanied by a poster session, plenary lecture and several workshops. Student participation was especially encouraged and, partly as a result of industry and University sponsorship (see below), subsidised places and travel bursaries helped to boost student delegates to almost one third of the overall total attendance. One of the key roles of the AAC has been to promote the work of the region's archaeological scientists by producing refereed publications of conference papers. As academic publication has radically changed in recent years so has the publication format and venues for conference publications. Rather than producing a single conference proceedings, papers from the 2005 AAC can be found in a variety of international journals, including Lithic Technology, Internet Archaeology, Archaeometry and the Journal of Archaeological Science. This volume presents original research papers from three key subject areas covered in the conferenc...
