What is Constraining the minimum age of Daraki-Chattan rock art in India by OSL dating and petrographic analyses about?
Ongoing work in Daraki-Chattan cave, India, has revealed important Paleolithic rock art (petroglyphs) in the form of cupules. The site is rich in stone tools of Acheulian industry to Oldowan-like industry including several hammerstones. The present investigation concerns a further detailed methodological and complementary approach for dating a quartz-arenite sandstone clast from just above the lowest exfoliated cupule, combining surface luminescence chronology with petrography. The optically stimulated luminescence equivalent dose profiles versus depth from quartz were studied to date this clast. Two different dose-depth profiles were measured spanning to 28 mm depth, one natural depth profile and one for a sample following exposure to daylight for nine months. Equivalent dose versus depth profiles indicate bleaching in several millimeters. Varied spatial luminescence response, its effect on the luminescence-depth profiles and interpretation to circumvent minor anomalies are fully discussed in terms of non-luminescent/dull faint minerals, coating, and inhomogeneous distribution of feldspars. Thin section analysis was performed using both optical and cathodoluminescence microscopy.
