“…3). The OSL ages of sand dunes in this study are fairly consistent with the results reported by Singhvi et al (1982), Chawla et al (1992), Juyal et al (2003), and Saini and Mujtaba (2010). Results show that dunebuilding activity in the Thar Desert had already started at ca.…”

“…During 12-8 ka, aeolian deposition was subdued because of enhanced moisture. Saini and Mujtaba (2010), used optically stimulated luminescence (OSL) dating based on the single aliquot regenerative-dose (SAR) protocol (Murray and Wintle, 2000). They found that the palaeochannel identified between Fatehabad and Hosanga, in the northwestern part of Haryana, received sufficient water supplies between 5.9 ka and 4.3 ka.…”

Quartz OSL dating of sand dunes in Ghaggar Basin, northwestern India

Several studies have used luminescence dating to investigate sand mobilization activity in extreme western areas and the southern margin of the Thar Desert, India. However, room exists for a chronology of sand profiles for the northern margins of the Thar Desert. The Ghaggar River flood plain at Rajasthan, northwestern India, in the northern margin of the Thar Desert, is bordered by sand dunes. Elucidation of the environmental changes of the Ghaggar Basin requires knowledge of many aspects of sand dune formation. We measured optically stimulated luminescence (OSL) using the single aliquot regenerative-dose (SAR) protocol for sand of eight palaeo-dunes and two flood silts of both sides of the present Ghaggar Basin and Chautang Basin flood plains. Their OSL ages were obtained respectively, as 15-10 ka or 5 ka, and 9-8 ka. Results of this study reinforce the hypothesis that sand dune deposition had started or had already been completed by 15-10 ka. Aeolian deposition was subdued by enhanced moisture during 9-8 ka. Our interpretation is that, at least since 5 ka, the scale of the flood plain of the Ghaggar River has remained equivalent to that of the present day.

“…Similar, very fine-grained infill was also documented by Saini et al 45, 46 along a section of the Ghaggar–Hakra palaeochannel. Thus, despite the diversion of the Sutlej, some fluvial flow and deposition of fine sediment continued in the topographic low formed by the relict valley.…”

Counter-intuitive influence of Himalayan river morphodynamics on Indus Civilisation urban settlements

et al. 2017

Urbanism in the Bronze-age Indus Civilisation (~4.6–3.9 thousand years before the present, ka) has been linked to water resources provided by large Himalayan river systems, although the largest concentrations of urban-scale Indus settlements are located far from extant Himalayan rivers. Here we analyse the sedimentary architecture, chronology and provenance of a major palaeochannel associated with many of these settlements. We show that the palaeochannel is a former course of the Sutlej River, the third largest of the present-day Himalayan rivers. Using optically stimulated luminescence dating of sand grains, we demonstrate that flow of the Sutlej in this course terminated considerably earlier than Indus occupation, with diversion to its present course complete shortly after ~8 ka. Indus urban settlements thus developed along an abandoned river valley rather than an active Himalayan river. Confinement of the Sutlej to its present incised course after ~8 ka likely reduced its propensity to re-route frequently thus enabling long-term stability for Indus settlements sited along the relict palaeochannel.

“…The degree of bleaching is evaluable from histograms as shown in Fig. 2 for each measured sample (Olley et al, 1998;Murray and Olley, 2002;Goedicke, 2003;Saini and Mujtaba, 2010). The individual ED values were entered into bins of 0.1 Gy and so the frequency distributions were obtained.…”

“…The thermal transfer effects were studied through the behaviour of ED and recovery test values against preheating temperature (Choi et al, 2003;Thomas et al, 2003;Kiyak and Canel, 2006). In order to investigate the degree of bleaching, the ED frequency distributions (Olley et al, 1998;Murray and Olley, 2002;Goedicke, 2003;Saini and Mujtaba, 2010) and time of bleaching in the easy-to-bleach OSL traps (Agersnap Larsen et al, 2000) were studied. The OSL ages were obtained using the Central Age Model (CAM) (Galbraith et al, 1999) and the results were compared with TL dating from bricks associated with the mortars.…”

Abstract:In the last years the mortar dating through Optically Stimulated Luminescence (OSL) techniques has become a viable support for chronological estimations (date of construction or restoration episodes) of historical buildings. However, the dating of mortar has still open issues mainly regarding the assessment of the bleaching degree of quartz, the analysis of the OSL processes for this type of samples and the need to do appropriate tests for the most correct evaluation of the equivalent dose. This paper discusses the results obtained by OSL dating (blue diode stimulation) on the polymineral fine grain phase, enriched in quartz, extracted from lime mortar samples collected from different sites. Thermal transfer effects, through the behaviour of Equivalent Dose (ED) and recovery tests, degree and time of bleaching were studied. For each mortar sample the adjacent brick was collected; in some cases, sampling of the bricks bracketing a mortar layer was a possibility, thus obtaining a direct comparison with the standard thermoluminescence (TL) dating on the bricks. The results obtained show, for this set of samples, the possibility of dating the mortars through the use of the fine grain fraction provided of a suitable chemical-physical preparation procedure and the verification of the bleaching conditions.
