The estimation of using the fast and medium components in fired quartz from archaeological site Karakorum, Mongolia

OSL and TL characteristics of fine grain quartz from Mongolian prehistoric pottery used for dating

“…Studies of Optically Stimulated Luminescence (OSL) from heated brick (Bøtter-Jensen et al, 2000) for retrospective dosimetry and from archaeological bricks/tiles (Solongo et al, 2006;Bailiff, 2007;Solongo, 2008) for historical studies in the interpretation and reconstruction of building chronologies are focused on the precise dose evaluation in fired quartz. For the determination of the absorbed dose using Single-Aliquot Regenerative (SAR) procedures (Wintle and Murray, 2006) provide accurate estimates of the dose for quartz dominated by fast OSL component.…”

Luminescence Dating of an Ancient Walled Settlement in Orkhon Valley, Mongolia

“…A basic assumption contained within the OSL approach is that the traps are completely empty of all trapped charge by sunlight during the event, which is being dated. This assumption appears to be the case with ceramics and bricks during the firing process; fired clay brick samples were successfully dated by the thermoluminescence (TL), optically stimulated luminescence (OSL) and post-infrared stimulated (pIRIR) techniques [21], [24], [20]; using different brick samples they were able to reconstruct the construction of the palatial complex, the palace and the city walls in Karakorum -the ancient capital of the Mongol Empire. However, for construction of walls and ramparts, sediment embedded within the wall may have been incorporated at various stages of the construction process, and from various sources, and may not necessarily have completely reset the OSL signal.…”

“…A quartz fast component [4] is the signal used for D e evaluation using the single aliquot regenerative-¬dose protocol by [25]. The ratio of fast to medium component leads to the scatter in D e distributions [24,8]. The effect of the medium component on the dose evaluation and the ratio of fast to medium was observed for heated bricks [24].…”

WHAT THE BRICKS TELL US FROM A TEMPLE AT BURKHAN KHALDUN MOUNTAINS: CHRONOLOGICAL INSIGHTS FROM pIRIR LUMINESCENCE

“…Extensive luminescence studies on bricks samples from Karakorum, Mongolia revealed the effect of the strong medium component on the dose evaluation [7] in heated quartz extracted from blue-grey colored bricks. In contrast, the red-colored brick showed a high OSL intensity with dominant fast component.…”

“…In contrast, the red-colored brick showed a high OSL intensity with dominant fast component. In particular, a comparative study of quartz and feldspar doses was carried out [8] in order to get an accurate dose estimate on the chronology of the brick production [7], as well as the construction phases of the Buddhist temple complex at the Karakorum [8].…”
