“…The fill material used is consistently limestone with minor contaminants present from the processing of the limestone to form lime. This finding is similar to those from other Maya sites where limestone is the only fill used (Huenda-Tanabe et al, 2004). The combination of analytical techniques in this study has provided a more thorough understanding of sample composition, enabling enhanced differentiation between the samples.…”

“…Lime stucco requires the addition of particulate material to reduce shrinkage and cracking when drying. This material can be crushed limestone, quartz sand, and in some instances volcanic ash has also been used (Huenda-Tanabe et al, 2004). The angular crushed particles present in these samples are not consistent with the use of water-rounded rock or sand as the filler.…”

“…While it has been used to identify pigments on rock art (Edwards et al, 1999;Mortimore et al, 2004), frescos (Bikiaris et al, 1999;Edwards et al, 2002Edwards et al, , 2003b and painted pottery (de Waal, 2004), little work has been focused on Maya stucco and pigments. Some early petrographic and X-ray diffraction analysis determined the composition of the stucco and mortar for different Maya sites (Hansen et al, 1997;Huenda-Tanabe et al, 2004;Littmann, 1958). Early pigment studies focused on the composition of the distinctive pigment Maya Blue, a stable combination of indigo and palygorskite clay (Sanchez del Rio et al, 2004).…”

Micro-Raman spectroscopy has been applied to painted stucco samples from three buildings at the Maya site of Copan, Honduras. The buildings, Clavel (AD 450e550), Ani (AD550e650) and Structure 10L-22 (AD730,) date from three phases of the Classic Period (AD400e820) acropolis construction. The red pigment has been identified as haematite and the stucco as a mixture of calcite particles dispersed throughout a calcite based lime wash stucco. The physical structure of the stucco changed through time, indicating a refining of production techniques over this period. By combining Micro-Raman spectroscopy with other micro-ATR infrared spectroscopy and environmental scanning electron microscopy a detailed investigation of the materials and production techniques used to decorate these buildings has been made. Differences in the mineralogy of the red pigment used on each building indicate a different geological pigment source for each period.

“…AD 650. Manzanilla (2003, p. 96; see also Hueda-Tanabe et al 2004;Solar 2006a) draws on archaeomagnetic dates to conclude that the burning and elite collapse happened a century earlier, ca. AD 550.…”

Teotihuacan in the northeastern Basin of Mexico was an unusually large and influential early city and state. This article reviews recent research trends in Teotihuacan from its founding and explosive growth ca. 100 BC into the largest city in Mesoamerica. Biogenetics provide details of how immigration fueled the city's growth and shaped its multiethnic composition and link Teotihuacan to other parts of the central highlands and more distant regions. Urban theory highlights the importance of neighborhoods and how their composition changed. Collective aspects of irrigation, markets, warfare and the military, and ideology encouraged the development of Teotihuacan's corporate governance. Although Teotihuacan politically dominated central Mexico, its control over the regional economy was not as centralized. Beyond its hinterland, Teotihuacan's foreign relations were a mosaic of trade diasporas, diplomatic exchanges, pilgrimages, emulation, and strategic direct interventions of limited duration. As its foreign influence retracted, Teotihuacan faced challenges from its hinterlands and intermediate elites and factions that culminated in the burning and desecration of the urban center. The Epiclassic saw the change from Teotihuacan's regional state to city-states and confederations. Although much reduced in size, Postclassic Teotihuacan retained an enormous legacy that subsequent states sought for their historical validation.

“…It is worth also noting that the past decade has led to new projects targeting the construction of regional records outside the European region. In particular the use of more novel materials such as lime plasters (e.g., in Mexico, Hueda-Tanabe et al 2004), non-welded pyroclastic deposits (e.g., in West Indies, and slag deposits from copper mining (e.g., in the middle east, BenYosef et al 2008aBenYosef et al , 2008bBenYosef et al , 2009, offer promise of extending the archeomagnetic record in both time and space. Figure 7 demonstrates that large changes in field strength (10-15 µT) commonly occur on time-scales of just a few hundred years.…”

The Magnetic Field of Planet Earth

The magnetic field of the Earth is by far the best documented magnetic field of all known planets. Considerable progress has been made in our understanding of its characteristics and properties, thanks to the convergence of many different approaches and to the remarkable fact that surface rocks have quietly recorded much of its history. The usefulness of magnetic field charts for navigation and the dedication of a few individuals have also led to the patient construction of some of the longest series of quantitative observations in the history of science. More recently even more systematic observations have been made possible from space, leading to the possibility of observing the Earth's magnetic field in much more details than was previously possible. The progressive increase in computer power was also crucial, leading to advanced ways of handling and analyzing this considerable corpus G. Hulot ( ) G. Hulot et al. of data. This possibility, together with the recent development of numerical simulations, has led to the development of a very active field in Earth science. In this paper, we make an attempt to provide an overview of where the scientific community currently stands in terms of observing, interpreting and understanding the past and present behavior of the so-called main magnetic field produced within the Earth's core. The various types of data are introduced and their specific properties explained. The way those data can be used to derive the time evolution of the core field, when this is possible, or statistical information, when no other option is available, is next described. Special care is taken to explain how information derived from each type of data can be patched together into a consistent description of how the core field has been behaving in the past. Interpretations of this behavior, from the shortest (1 yr) to the longest (virtually the age of the Earth) time scales are finally reviewed, underlining the respective roles of the magnetohydodynamics at work in the core, and of the slow dynamic evolution of the planet as a whole.
