Abstract:

Sand samples were collected at different locations from the Huguangyan Maar Lake region in Zhanjiang, Guangdong province in south China. Thermoluminescence(TL) and optical stimulated luminescence(OSL)were measured with coarse grain technique. The TL and OSL dose response were analyzed and their ancient doses were calculated. The result shows that ancient doses measured with TL technique differ from those measured with OSL technique for the same sample, whereas for the samples whose TL ancient dose is close to the veraciousness, there were no evident degree of difference between the ancient doses by OSL and TL.The experiments and analyses can be used for reference in Quaternary period volcano dating.
