By 2019, a long brick platform with some structures was exposed when the Thamirabarani River, southernmost river in city of Thirunelveli, dried up. The civic society rejoiced at discovery structure as it thought to be palace first capital Pandya dynasty, an ancient Tamil dynasty southern India. Two bricks were removed from determine their ages using luminescence dating method, and geochemical composition analyzed X-ray fluorescence method. composed mud that underwent intermediate silicate...
In this study, naturally occurring jarosite samples from Kachchh India (considered to be Martian analogue) were characterized using Fourier Transform Infrared Spectroscopy (FTIR), Cathodoluminescence- Energy Dispersive X-ray (CL-EDXS) and luminescence (thermoluminescence (TL), blue infrared stimulated (BSL IRSL) methods. FTIR CL-EDXS studies suggested that preserves its characteristics even after annealing the 450°C. This facilitated (TL/BSL/IRSL) assess potential use of luminescence-dating...
Quartz is an omnipresent abundant natural mineral, used for luminescence dating. Lately, quartz optically stimulated (OSL) technique widely to estimate the equivalent doses (De) dating geological events (up 250 Gy, limited by saturation). Some works report thermoluminescence (TL) saturation around ~ (10-40) kGy. Still dose estimates such high radiation (HRD) range are not achieved. Significant research exists about response low ranges (<250 Gy) but studies done HRDs (>1 kGy)....
