“…La elección de la función de ajuste es crucial para el cálculo de la dosis equivalente de estas muestras (Duval et al 2009). En el caso del cuarzo, la utilizada normal (o exclusivamente) en la bibliografía es una función SSE (por ejemplo Rink et al 2007;Liu et al 2010;Voinchet et al 2010). Sin embargo, su uso en las muestras de Vallparadís plantea algunas dificultades: (1) apenas se ajusta a los datos experimentales, algo especialmente evidente en las dosis de radiación bajas (véanse ampliaciones en la Fig.…”

Excavated between 2005 and 2007, the site of Vallparadís (Terrassa, Spain) has given an abundant and diversified fauna associated with a rich Mode 1 industry. In order to complete the chronostratigraphic framework, we performed ESR and combined US-ESR dating applied to quartz grains extracted from sediments and fossil teeth, respectively. The results obtained are very significant, giving a weighted mean ESR age of 0.83 ± 0.13 Ma (2σ) for the reference archaeological level of the site (level 10) and another of 0.79 ± 0.23 Ma (2σ) for the archaeological level 12 of the Vallparadís sequence. These ESR results are in total agreement with the ones derived from biochronology and paleomagnetism. This whole dataset allows the elaboration of a reliable and consistent chronostratigraphic framework which chronologically places Vallparadís site in the late Early Pleistocene period, i.e. within a time range comprised between Jaramillo and Brunhes geomagnetic events. Consequently, as well as Gran Dolina-TD6 and Sima del Elefante- TE9 sites, in Atapuerca, Burgos, Vallparadís can be therefore considered as a key site for the study of early hominid settlements in Europe.

Excavado entre 2005 y 2007, el yacimiento de Vallparadís (Terrassa, España) ha aportado una fauna rica y diversa en asociación con un importante conjunto lítico de Modo 1. Con el objetivo de completar el marco cronoestratigráfico, se hicieron dataciones por los métodos de Resonancia Paramagnética Electrónica (Electron Spin Resonance, ESR) y ESR combinada con uranio-torio sobre algunas muestras de granos de cuarzo extraídos de sedimentos y dientes fósiles, respectivamente. Los resultados obtenidos son muy significativos, ofreciendo edades ESR promedias de 0,83 ± 0,13 Ma (2σ) para el nivel arqueológico de referencia del yacimiento (nivel 10) y de 0,79 ± 0,23 Ma (2σ) para el nivel arqueológico 12 de la secuencia de Vallparadís. Dichos resultados por ESR concuerdan con los obtenidos a partir de la biocronología y del paleomagnetismo. El yacimiento de Vallparadís dispone ahora de un marco cronoestratigráfico fiable y coherente, que permite situarlo cronológicamente a finales del Pleistoceno inferior, dentro de un rango temporal comprendido entre los eventos geomagnéticos de Jaramillo y Brunhes. Dicho yacimiento junto a los de Gran Dolina TD-6 y Sima del Elefante TE-9, en Atapuerca, Burgos, se posiciona como un yacimiento clave para el estudio de los primeros poblamientos humanos de Europa

ESR dating of the Donggutuo Palaeolithic site in the Nihewan Basin, northern China

Abstract:The fluvio-lacustrine sequences in the Nihewan Basin, northern China, provide important terrestrial archives about Palaeolithic settlements and, therefore, about early human occupation in high northern latitude in East Asia. Here we present detailed ESR dating of the Donggutuo Palaeolithic site, located in this basin. Four levels A, B, C and E of the Donggutuo archaeological layer yield ESR ages ranging from 1060±129 ka to 1171±132 ka with a mean of 1119±132 ka. The ages are consistent with the paleomagnetic data, which show that the Donggutuo Palaeolithic site lies just below the onset of the Jaramillo normal subchron (0.99-1.07 Ma). Furthermore, our results indicate that the reliable ESR dating range of bleached quartz using Ti-Li centre can be effectively extended to 1100 ka and the Ti-Li centre was zeroed before the last deposition, which requires improvement of the understanding of the bleaching mechanism conditions.

“…The microwave power was 5 mW, modulation amplitude was 0.16 mT, conversion factor was 20.48 ms, time constant was 40.96 ms and spectrum resolution was 2048 bit (resulting in a total sweep time of 41.94 s). The Ti-Li center intensity was measured from the top of the peak at g=1.979 to the bottom at g=1.913 (Rink et al, 2007;Liu et al, 2010a), from P1 to P2 in Fig. 3.…”

“…In recent years, there has been a strong interest to apply ESR dating to quartz (e.g. Yokoyama et al, 1985;Tanaka et al, 1995;Laurent et al, 1998;Beerten et al, 2006;Rink et al, 2007;Liu et al, 2010a;Voinchet et al, 2004Voinchet et al, , 2010Tissoux et al, 2007Tissoux et al, , 2008Moreno et al, 2012). So it is worthwhile to use this method to develop the independent chronology for the river terrace at the east margin of the Tibetan Plateau.…”

“…The quartz Ti-Li center ESR signal (Toyoda et al, 2000;Rink et al, 2007) was used to date the river terrace (T3-T6) samples which could be older than 100 ka assuming an initial zeroing of the signal, because bleaching experiments (Toyoda et al, 2000;Tissoux et al, 2007;Gao et al, 2009) have shown that the quartz Ti-Li center ESR signal can be completely bleached after the equivalent of a few days of direct sunlight exposure, that is very quick for quartz ESR centers. The method promises to provide reliable geochronology for quaternary tectonic uplift and climatic change research.…”

ESR geochronology of the Minjiang River terraces at Wenchuan, eastern margin of Tibetan Plateau, China

et al. 2013

Abstract:The Minjiang River terrace along the Longmen Shan fault zone near Wenchuan, at the eastern margin of the Tibetan Plateau, China, provides archives for tectonic activity and quaternary climate change. However, previous studies were not able to provide ages older than 100 ka due to the limitations of dating material or/and methods applied to date the fluvial sediments. In this study, we used the ESR signal of the Ti-Li center in quartz to obtain the ages of four higher terraces (T3-T6). According to the results, the terraces T3 to T6 were formed at 64±19 ka, 101±15 ka, 153±33 ka, and 423±115 ka, respectively. Combined with previous studies, these results indicate that the formations of all terraces correspond to glacial/interglacial transition periods, such as, T1-T5 being correlated to MIS2/1, MIS4/3, MIS5d/5c, and MIS6/5e respectively, while T6 probably to MIS12/11. According to these data, it is found that the average incision rate was significantly higher over the last 150 ka than that previous 100 ka (250 to 150 ka). As both tectonics and climate have affected the formation of these terraces, in addition to the overall uplifting of Tibetan Plateau, the regional uplift due to isostasy would be an additional tectonic factor in the formation of river terraces in the eastern margin of Tibetan plateau.
